This booklet is one of the outcomes of the APEC Seminars and Training Courses in Legal Metrology titled ‘Training Course on CNG (Compressed Natural Gas) Fuel Dispensers’ that was held on June 27-30, 2006 at the Grand BlueWave Hotel in Shah Alam, Malaysia. This course was organized as a follow-up of the Training Course on Fuel Dispensers conducted in April 2005 in Thailand but intended to pursue specific understanding of CNG fuel dispensers. It was organized by the Asia-Pacific Legal Metrology Forum (APLMF) with a support fund of APEC-TILF (Trade and Investment Liberalization and Facilitation) program, CTI-11/2006T. The training course was also supported by (1) SIRIM Berhad, Malaysia; (2) Ministry of Domestic Trade and Consumer Affairs of Malaysia; (3) Department of Food and Agriculture, State of California, USA; (4) Petronas NGV Sdn. Berhad in Malaysia; (5) Metrology Corporation Malaysia Sdn. Berhad; and (6) National Metrology Institute of Japan (NMIJ). Having this result, I would like to extend my sincere gratitude to Mr. Md Nor Md Chik of SIRIM Berhad; Mr. Mohd Roslan Mahayuddin of the Ministry of Domestic Trade and Consumer Affairs, Malaysia; Mr. Ir. Hasmad B. Ahmad of Petronas NGV Sdn. Bhd.; Mr. Ismail Husin of Metrology Corporation (M) Sdn. Bhd.; Mr. Charles Nelson and Mr. Robert Norman Ingram of the Department of Food and Agriculture, State of California, USA; and the APLMF Working Group on Training Coordination chaired by Mrs. Marian Haire of National Measurement Institute Australia. Also, special thanks should be extended to the APEC Secretariat for their great contributions.

We have conducted the surveys among the APEC member economies concerning seminar and training programs in legal metrology to find their needs as well as possible resources which would be available for the region. The survey shows that there is a strong need for a new training course designed specifically on CNG fuel dispensers that is one of the categories of instruments in legal metrology; this field has becoming a great interest of the member economies due to the increasing demand for alternative source of fuel for automobiles. However, the legal metrological control on CNG fuel dispensers has been just started. International recommendation on such dispensers has not been standardized in the OIML Recommendations; the draft recommendation is under review. Taking account of such current situation, we considered it is essential for the member economies to learn a practical verification procedure from the United States where CNG has been widely used as well as to exchange information with all participants about the current situation of CNG in each economy. We believe such a training course will provide the APEC and APLMF economies an opportunity to have a common technical base of understandings that may lead to the next international step to enable a proper proposal to the International Standard such as ISO or

1

OIML Recommendation.

The main target of this training course was to assist the experts in charge of the legal metrological control on CNG in the APEC / APLMF member economies to develop deeper understanding of the current situation including the verification of CNG fuel dispensers in performing inspection procedures. Thus the training course would also help the experts to learn how CNG system is used and controlled in the major CNG markets.

In view of these situations, this training course concerning CNG fuel dispensers had been planned and completed successfully so as to settle a sure basis of confidence in legal metrology related to the measurement of CNG fuel dispensers within the Asia-Pacific region. I would like to say that this is certainly a valuable first step to fruitful activities in legal metrology related to CNG systems in the Asia-Pacific region.

I am really pleased to have this outcome from the training course and again deeply appreciate APEC Secretariat’s generosity in contributing to the development in legal metrology among the APLMF member economies.

Summary Report on the APLMF Training Course for the Verification Inspection of Compressed Natural Gas

Fuel Dispensers While supplies are being exhausted as the worlds demand for petroleum increases, alternative sources of motor fuel are becoming more widespread. Compressed natural gas (CNG) is one of the alternatives on the rise. Some economies that have no CNG users currently have plans for implementing use within a short period of time. To help promote the continued confidence of an equitable marketplace in international trade, it becomes necessary to address measurement activities in relatively new technical arenas. Therefore, APEC and APLMF presented the training course on CNG Fuel Dispensers. The APEC/APLMF Training Course on CNG Fuel Dispensers was held in Shah Alam, Malaysia from June 27 to June 30, 2006. Training course material was developed and presented by Mr. Charles Nelson and Mr. Robert Norman Ingram from Division of Measurement Standards, Department of Food and Agriculture, State of California, USA. The course was organized by the APLMF and APEC. Supporting organizations were: National Metrology Laboratory (NML) SIRIM Berhad, Malaysia, Ministry of Domestic Trade and Consumer Affairs, Malaysia, Petronas NGV Sdn. Berhad in Malaysia, Metrology Corporation Malaysia Sdn. Berhad, and National Metrology Institute of Japan (NMIJ). The course was attended by 36 trainees representing 14 economies. The training course was designed to provide training on general safety, properties of CNG, dispenser components, requirements on dispensers, and procedures for inspection including necessary equipments and accessories. The course included a power point presentation with lectures in a classroom and field training at a facility with CNG dispensers. In addition, the course helped the member economies become more familiar with the processes involving technical requirements of pattern approval and verification inspection of CNG dispensers, and met the APEC and APLMF objective to harmonise with Organisation Internationale De Metrologie Legale (OIML) recommendations with an overview and comparison of OIML document TC 8 SC 7. Each attending member economy contributed to the course with a presentation regarding the use of CNG and their experience associated with the management of pattern approval and/or verification inspection within their respective economies. These presentations revealed the diversifying use of CNG as a motor fuel, from projected use to a narrow scope of limited government fleet and local municipal transportation to widespread use in private vehicles. First day closure brought an enlightened and impressive tour of National Metrology Laboratory (NML) SIRIM Berhad, Malaysia who is the keeper of Malaysia’s Primary Physical Standards of Measurement. Two days of lecture reinforced with a power point presentation gave the trainees an opportunity to interact and contribute to the training. The course was presented using the gravimetric procedure in verifying the dispenser delivery accuracy. This procedure incorporates the practice of determining the weighing element error in relation to its zero error. Once determined, the

3

weighing element error is applied as a correction to the net load of CNG. Mr. Do Viet Hung, the representative from Viet Nam offered an alternative method for determining the weighing element error, when considering the zero error. Although either method would result with the correct error, the alternative is perhaps more consistent with the OIML procedures laid out in OIML document R 76-2. The field training was very successful due to a highly co-ordinated effort from Dr. Abdul Rahman Mohamed, Senior Metrologist and Head of Flow Measurement, National Metrology Laboratory (NML) SIRIM Berhad, Malaysia, who arranged for transportation, and critical equipment needs. Mr. Mohd Sherman Nabiel Bin Abdul Basit of Petronas NGV Sdn. Bhd. also contributed to the highly co-ordinated effort of supplying critical equipment needs as well as his personal assistance in handling the gas cylinders. The gravimetric method for delivery measurement accuracy presented by the trainers was demonstrated first. As in the lecture, the field training also yielded an opportunity for the trainees to interact and contribute with the demonstration by Dr. Abdul Rahman Mohamed on the use of a master meter as a transfer standard for delivery accuracy verification. In between all the logistical and technical issues, the host in Malaysia provided for a wonderful time of international social interaction encouraging trade and investment liberalization by offering the most delicious cuisine representing a variety of international tastes as well as the best that Malaysia has to offer. Further enchasing opportunities of international social interaction, the host provided transportation for city tours of Kuala Lumpur and the luxurious new central government city Putrajaya, to be completed in 2010. For the farewell dinner, a most wonderful evening of entertainment, festivities, and cuisine were provided by the host & APLMF. The sponsorships by the organizers and the host economies of the APEC/APLMF training courses provide not only an atmosphere of harmonization of the technical regulations that define parameters of measurement activities in commerce, but also perpetuate a true harmonization in togetherness of humanity.

INTRODUCTION TO CNG What is Natural Gas?

Natural gas derives from decayed matter over a long period of time and under tremendous heat and pressure

Natural gas is not pure methane or a homogenousmixture, but varies in composition seasonally and by location.

NATURAL GAS….Is naturally occurring mixture of hydrocarbon and non-hydrocarbon gases found in porous geological formations beneath the earth’s surface. Natural gas basically comes from organic material that was decomposed under pressure.

CNG Properties Properties and Characteristics of CNG

Specific gravity of gas components (air = 1.0)

Methane 0.5

Ethane 1.0Propane 1.5

Butanes 2.0

Pentanes 2.4

Hexanes 2.9 CO2 1.5

Nitrogen 0.9

Others consist of…

As you can see the natural gas contains various compositions that vary from locations and sources. This pie is showing the approximation of what natural gas consist of.

CNG SAFETY

Importance of Safety

* Safety is EXTREMELY IMPORTANT ** Re-stress in field training ** Cannot be over-stressed *

* If you don’t learn anything else…learn that safety comes first ** Unsafe practices can harm not only yourself, but also others *

We all have been preached about Safety time and time again when working in dangerous elements. I can’t emphasize enough your safety is important as well the individuals around you. If you see something that looks unsafe let the personnel at the site who are responsible for your safety to know what your concerns are.

If we recall CHARLES’S LAW…The volume of a gas at constant pressure is directly proportional to the temperature. As temperature changes so will pressure.

CNG SAFETY

PRESSURE

What is the pressure rating of your Test Cylinder?

200 Bar?

Or

250 Bar?

Let’s talk about pressure rating of a cylinder that will be used in the testing …when you get a cylinder you will need to make a determination if that cylinder will be suitable for the application. What is the cylinder rated for? Cryogenic, propane or CNG? You can’t have one for all. Every tank or pressure vessel are design for a specific application…there are good reasons why. What is the maximum pressure range of that vessel? 200 bar? Or is 250 bar?

13

CNG SAFETY

PRESSURE

What is the pressure rating of your Test Cylinder?

Markings are required…

To Identify pressure limits

Identification markings are required, if there are no markings to identify what the cylinder is rated for and its limit… I would not bother to use it if it does not have the qualifying statement required on pressure vessels. As I mentioned earlier Safety comes first.

CNG SAFETY

PRESSURE

Additional Safety feature…

NGV Nozzles and Connectors

Nozzles… Let’s look at the fittings, notice the design of the connectors, they are not exactly identical with each other…there is a reason for this…The storage tanks varied in their pressure ratings, for example if you have a tank that is rated for 200 bar and you go to a CNG dispenser that dispenses at the rate of 250 bar you will obviously would over fill your tank and create a liability situation. Because the connectors are different, in this case, it is design to have the ability to only connect to matching nozzles that are dispensing at 200 bar. Now if this was the other way around…the tank rated at 250 bar you would still be able to connect to a 200 bar dispenser, the concept of the connector is so you could not connect to a higher pressure rating than your connector allowed.

CNG SAFETY

PRESSURE

Fuel storage cylinder types:

1: All metal (steel or aluminum)…………..130kg2: Hoop-wrapped steel or aluminum…….120kg3: Fully-wrapped steel or aluminum…….115kg4: All composite (non-metallic)……………..85kg

Example: Cylinder holds 30kg of CNG

There are four types of CNG cylinders, Type 1 is the heaviest of all CNG cylinder types. Type 2 is metal liner wrapped reinforced by composite wrap in the mid section of the tank, so basically the pressure stress factor is supported by 50% on the metal liner and 50% on the composite wrap. Type 3 is the same as type 2, the only difference is the tank is fully wrapped. Type 4 is all non-metallic, normally the tank is a plastic liner with all composite wrapping.

CNG SAFETY

PRESSURE

Preventive maintenance…

Make a visual inspection of cylinder before use

Notice the lining around the tank? When you see damage from abrasion or other form of mishandling of pressure tanks it is best to have it repaired or replace. We basically leave the responsibility of the operator or maintenance personnel to provide the cylinder to accommodate the test.

Hazards from overfill or damaged linings

This particular tanks is made of composite type of material. Notice the white portion of the ruptured tank, That is the plastic liner. The second layer the graphite wrapping material and last and outer portion is the glass or carbon fiber material which is a protection layer of the tank. This rupture was due to defect or cuts in the composite lining, all it takes is a small cut in the lining to compremise the integrity of the pressure vessel.

AKA AKA Blowing and levelingBlowing and levelingeverything everything very effectivelyvery effectively

The term “BLEVE” Is an abbreviation of Boiling liquid expanding vapor exploding.Another word that fire departments say is Blowing and leveling everything very effectively. A BLEVE can occur in a vessel that stores a substance that is usually a gas at atmospheric pressure but is a liquid when pressurized (for example, liquefied petroleum gas). The substance will be stored partly in liquid form, with a gaseous vapour above the liquid filling the remainder of the container.If the vessel is ruptured — for example, due to corrosion, or failure under pressure — the vapour portion may rapidly leak, dropping the pressure inside the container and releasing a wave of overpressure from the point of rupture. This sudden drop in pressure inside the container causes violent boiling of the liquid, which rapidly liberates large amounts of vapour in the process. The pressure of this vapour can be extremely high, causing a second, much more significant wave of overpressure (i.e., an explosion) which may completely destroy the storage vessel and project it as shrapnel over the surrounding area.A BLEVE does not require a flammable substance to occur, and therefore is not usually considered a type of chemical explosion. However, if the substance involved is flammable, it is likely that the resulting cloud of the substance will ignite after the BLEVE proper has occurred, forming a fireball and possibly a fuel-air explosion. BLEVEs can also be caused by an external fire nearby the storage vessel causing heating of the contents and pressure build-up.

Types of CNG Types of CNG ““FillingFilling”” StationsStations

CNG Dispensing StationsCNG Dispensing Stations

Time Filled

Time-fill stations fill Multiple number of vehicles at one time over a six- to eight-hour period. Compressors compress natural gas from pipeline pressure (0.5-7 bar) to the required vehicle pressure (170-250 bar). These stations are generally for vehicles such as school buses and utility trucks that return to a centrallocation and can fuel while parked for an extended period. But extended fueling time is needed because time-fill stations have relatively small compressors and no CNG storage.


Buffered Fill

Buffered fast-fill stations provide fast, continuous, high-volume fueling. Relatively large compressors run continuously during fueling, filling vehicles and, in the interval between vehicles, a CNG storage buffer. The storage buffer provides CNG to vehicles at the beginning of the fueling cycle and allows the compressor to run for long periods. Unlike CNG storage in cascade fast-fill systems, buffer storage is not separated into separate banks. Buffered fast-fill stations are suitable for quickly fueling large numbers of heavy-duty, high-fuel-capacity vehicles, such as transit buses.


Vehicle refueling appliances

Vehicle refueling appliances (VRAs) are like small time-fill stations, containing a small compressor and other equipment within a single unit. VRAs use natural gas from low-pressure pipelines found in many homes and businesses and require 220-volt, single-phase electricity.

18

CNG Dispensing StationsCNG Dispensing StationsCascade Filled

Cascade fast-fill stations provide fast and convenient fueling similar to that provided by conventional liquid fuel stations. CNG storage vessels arranged in cascades, or banks, are used to quickly fillvehicles during peak fueling times, when the compressors alone cannot meet demand. During off-peak times, the compressors refill the CNG storage cascades. These stations are suitable for fueling light-duty vehicles at public access stations where use patterns are random. They are also suitable for fueling fleets of light-duty vehicles, such as taxis and police cars, that require a fast fill and have peak fueling periods. Cascade fast-fill stations are not appropriate for continuous, high-volume fueling because the compressors are not large enough to provide a fast fill once theCNG storage has been depleted. Most of the several hundred public access CNG stations in North America use a cascade fast-fill system.

Vaporized Gas Utility Meter

To give you a visual view of what the system generally looks like…here are some of the photos. This is Utility meter own by the Gas Company.

19

Dryer/Cleaner

The gas dryer is used to remove water vapors from the gas and to dry it to a pressure dew point. Failure to dry the gas can result in vehicle engine problems.

Filters

Gas Filters are required and is recommended to be installed at various locations within the CNG compressor station otherwise there will be some serious maintenance issues as well as vehicles having plugged up fuel injector lines. They Filter out foreign particulates and solid matter.

Compressor

Gas compressor basically sucks in natural gas from pipeline and then compresses it out into a storage tank.

CNG Storage Tanks/Cylinders

The Storage tank here are the most common system we see at public fueling stations. Although they can be a single tank or multiples stacked like a triangle but they are generally much slower to fill. Notice there are 3 tanks? This is used to store gas at pressure higher than the vehicle tank pressure. This differential pressure is used to transfer the gas from the cascade into the vehicle. This system is typically divided into three banks: high, medium, and low. Any number of cascades can be connected together to increase storage capacity.

20

Priority Sequence Panel

The Priority system is used to divert gas from the compressor to the storage tank and is also integrated in the Emergency shutdown system which is used to isolate the storage cascade from the quick fill dispenser in the event of emergency shutdown.

System Controller

This component controls all of the operational features of the compressor and dispenser characteristics. This unit can also carry some of the metrological functions. Such as calibration of pulsecounts,

One major component is the “Card Reader” it may be internal within the dispenser or it may be external.

Equipment and Parts CNG DispensersBreak away coupling

Breakaway couplings are generally located at the base of the hose where it is connected to the dispenser. They are designed as safety feature to prevent someone from taking the dispenser home. There is a check valve that will snap closed when the downstream portion of the hose isdislocated from the downstream side of the coupling.

22

Equipment and Parts CNG DispensersIdentification Plate

Identification plate is another major part of the Identity of the dispenser. This plate contains the critical marking requirements Weights & Measures required.


Mass Flow Meter

Coriolis Mass FlowmetersCoriolis meters are the most widely used gas flow measuring device in CNG dispensers today. The measurement is based on the Coriolis force. The vibrating tubes are deformed by gas flowing through the tubes. The phase shift caused by the deformation of the vibrating measurement tubes is proportional to the mass flow rate of the gas and hence the meter provides true mass measurement.


Transmitter

Transmitters… They are the pulse or signal generator that sends gas flow measurement information via transmitter to the system controllor or primary customer display.


Metrological sealing and Calibration

The next major component is the sealing provisions of the meter. The sealing can be in many forms…1) lock and wire seal, 2) tamper proof seals, or audit trails.

General RequirementsGeneral Requirements

Application of general Application of general requirementsrequirements

This refers to what types of devices are subject to the general and specific codes. There is further explanation in the specific code that defines what that code is applicable to. Basically, the codes apply to: (a) commercial weighing and measuring equipment; that is, to weights and measures and weighing and measuring devices commercially used or employed in establishing the size, quantity, extent, area, or measurement of quantities, things, produce, or articles for distribution or consumption, purchased, offered, or submitted for sale, hire, or award, or in computing any basic charge or payment for services rendered on the basis of weight or measure.

(b)To any accessory attached to or used in connection with a commercial weighing or measuring device when such accessory is so designed that its operation affects the accuracy of the device.

(c)To weighing and measuring equipment in official use for the enforcement of law or for the collection of statistical information by government agencies.


Application of Application of maintenance and maintenance and acceptance tolerancesacceptance tolerances

In the U. S. There are two types of tolerances, acceptance and maintenance and there are different application to each. Typically, acceptance tolerances apply to devices undergoing pattern or type approval. Maintenance tolerances apply to devices that have been in service that have pattern approval, but not always. The requirements are that acceptance tolerances shall apply to:

(a) equipment to be put into commercial use for the first time;(b) equipment that has been placed in commercial service within the preceding 30

days and is being officially tested for the first time;(c) equipment that has been returned to commercial service following official

rejection for failure to conform to per-formance requirements and is being officially tested for the first time within 30 days after corrective service;

(d) equipment that is being officially tested for the first time within 30 days after major reconditioning or overhaul; and

(e) equipment undergoing type evaluation.(f) Maintenance tolerances shall apply to equipment in actual use, except as

provided above.


Accessibility for Accessibility for inspectioninspection

This is one of my favorites. Accessibility for inspection, testing, and sealing. The requirement is that a device shall be located, or such facilities for normal access thereto shall be provided, to permit:

(a) inspecting and testing the device;(b) inspecting and applying security seals to the device; and(c) readily bringing the testing equipment of the weights and measures

official to the device by customary means and in the amount and size deemed necessary by such official for the proper conduct of the test.

Otherwise, it shall be the responsibility of the device owner or operator to supply such special facilities, including such labor as may be needed to inspect, test, and seal the device, and to transport the testing equipment to and from the device, as required by the weights and measures official.There is a sister code for this section entitled assistance in testing operations and the requirement is that if the design, construction, or location of any device is such as to require a testing procedure involving special equipment or acces-sories or an abnormal amount of labor, such equipment, accessories, and labor shall be supplied by the owner or operator of the device as required by the weights and measures official.


Unattended money Unattended money operated devicesoperated devices

This is a requirement for devices that accept cash or coin and are unattended. The requirement for money operated devices, other than parking meters, shall have clearly and conspicuously displayed thereon, or immediately adjacent thereto, adequate information detailing the method for the return of monies paid when the product or service cannot be obtained. This information shall include the name, address, and phone number of the local responsible party for the device. This requirement does not apply to devices at locations where employees are present and responsible for resolving any monetary discrepancies for the customer.


Maintenance of Maintenance of equipmentequipmentUse of adjustmentsUse of adjustments

Lastly, my most favorite, the maintenance of equipment. It states that all equipment in service and all mechanisms and devices attached thereto or used in connection therewith shall be continuously maintained in proper operating condition throughout the period of such service. Equipment in service at a single place of business found to be in error predominantly in a direction favorable to the device user shall not be considered “maintained in a proper operating condition.”Another complement to this code is the use of adjustments:Weighing elements and measuring elements that are adjustable shall be adjusted only to correct those conditions that such elements are designed to control, and shall not be adjusted to compensate for defective or abnormal installation or accessories or for badly worn or otherwise defective parts of the assembly. Any faulty installation conditions shall be corrected, and any defective parts shall be renewed or suitably repaired, before adjustments are undertaken. Whenever equipment is adjusted, the adjustments shall be so made as to bring performance errors as close as practicable to zero value

As mentioned previously, the markings on the cylinder should state the pressure rating of the cylinder and a visual inspection should always be performed prior to use. Verify the presence of a pressure gauge fitted on the cylinder to prevent overfilling. In addition, it is good to check the fittings to see that they are compatible with the fittings from the nozzle at the end of the hose. Typically, a representative of the gas supplier, dispenser manufacturer, owner/user, or station maintenance will supply the cylinder and handle the gas. But sometimes they become involved in routine and overlook the simple and obvious, so it doesn’t hurt to double check.

Cylinder RequirementsCylinder Requirements

Size suitable to hold Size suitable to hold product flowing for 1 product flowing for 1 minute at the highest minute at the highest flow rate. flow rate.

In the U.S. the requirement for a cylinder size suitable to hold enough product flowing for one minute at the highest flow rate is a must for pattern or type approval but may not always be practical for routine tests, so our minimum requirement is a cylinder that will hold a 3 kg draft.

Weighing Element Selection Weighing Element Selection CriteriaCriteria

Inherently safe Inherently safe ––Suitable for explosive Suitable for explosive environments environments

OROR

Located outside of Located outside of classified area (1.5 classified area (1.5 metresmetres from hose from hose connection) connection)

If an intrinsically safe weighing element can not be obtained, then the weighing element must be located at least 1.5 meters outside of the classified area. The classified area is considered to be the hose connection to the dispenser. Another option is to have a battery powered weighing element.

Weighing Element Selection Weighing Element Selection CriteriaCriteria

Increment is dictated Increment is dictated by:by:Applicable Applicable tolerance tolerance on net load on net load of draftof draft

The size of the weighing element increment relative to the net load has a significant effect on the accuracy to which a device can be tested. The increment size will also affect the size of the test draft required. Therefore, part of the weighing element selection criteria is to have an increment value that is small enough to resolve this issue.

29

Applicable Tolerance Relationship to Applicable Tolerance Relationship to Weighing Element Increment Weighing Element Increment

Assume 2% tolerance on estimated draft of Assume 2% tolerance on estimated draft of 10 kg = 0.20 kg allowed on 10 kg draft10 kg = 0.20 kg allowed on 10 kg draft0.2 kg, x 0.1 =0.2 kg, x 0.1 =Maximum weighing element increment of Maximum weighing element increment of 0.02 kg0.02 kg

We must keep the error, which is caused by reading the weighing element, to an acceptably level for a single weighing. Therefore the value of the increment should not exceed 1/10 of the tolerance applied to the dispenser. Due to the fact that the errors occur at both the gross and tare weights, errors could represent as much as 20% of the tolerance.

Weighing Element Selection CriteriaWeighing Element Selection Criteria

Capacity is dictated by:Capacity is dictated by:Gross load Gross load of cylinderof cylinder

A combination of three approaches may be used to satisfy the selection criteria. Either a high resolution weighing element, the use of fractional weights, or a larger test draft is required. If the size of the test draft must be small due to the available cylinder, then the weighing element must have the appropriate division size.

Mass StandardsMass Standards

NIST 105NIST 105--1, class F1, class FOIML R111, class M1OIML R111, class M1

The required amount of test weights should be of sufficient amount to verify the weighing element to the capacity of the gross load of the cylinder when it is full. The fractional weights should be small enough to resolve 1/10 of the weighing element increment.

Mass StandardsMass Standards

Accreditations begin with the International Laboratory Accreditation Cooperation (ILAC) and the U. S. equivalent is the National Cooperation for Laboratory Accreditation (NACLA). In the U. S. if a laboratory has NACLA, they get ILAC. These bodies empower other agencies the right to give accreditations to metrology laboratories. When accreditation is achieved, it signifies that the laboratory has demonstrated that they have measurement proficiency through training and interlaboratory comparisons, as well as traceable standards. Our own state laboratory meets these requirement.

Explain the zone of uncertainty, and it’s role in determining the error as well as the role of the zero load error.Number 2, Self explanatory, how to apply number 1 in determining the weighing element error (uee of the formula). Number 3, understand specifically the methodology (what you do, how you do it and at what points you do it, at as well as why).

Weighing Element VerificationWeighing Element Verification

Level the weighing element

Before we begin this part I would like to add a footnote that this is going to be the most time consuming part of the procedure. The scale verification may even take as long as all the dispenser tests combined. It is the whole basis of the dispenser tolerance test. Therefore, be extremely careful and precise and do not hesitate to suspend testing if you have any doubts about the weighing elements performance or the environmental conditions under which you are testing. Choose a suitable location such as a flat smooth surface to place the weighing element. Check to see that when the cylinder is placed on the weighing element, both will be stable and not roll, tilt, or move. Chocks or wooden blocks may be used to help stabilize the cylinder. Every effort should be made to protect the weighing element fromenvironmental factors such as wind and rain.


The indication is 80.0 kgThe indication is 80.0 kg

As you use the fractional mass, you may experience the display “flickering” between increments. This is normal and indicates that you are in the “zone of uncertainty”. The zone of uncertainty is the display electronics interpretation of being between two different values (based on the load, the display cannot discern on what value to display). Ideally, in digital electronics, this occurs at the exact midpoint between two values. However, there are limits to this as well. When you first enter the zone, if you experience that the zone of uncertainty continues with the addition of fractional mass equal to more than 3/10 of the value of the increment, the weighing element is unsuitable for use. You may remedy this situation by changing the filtering of the weighing element. However, again this requires knowledge of changing configurationparameters or having sufficient technical data relating to the weighing element.


A fractional mass value of 0.250 kg is added to the weighing element

For the purpose of this demonstration we will leave the zero tracking on to assure a zero error at zero and to assure a good return to zero. To verify that the zero tracking is on, place a mass in the amount equal to 0.3 weighing element increment on the weighing element. You may see this value displayed for an instant and then a zero value or you may see the zero value continuously displayed. If the mass value remainsdisplayed, the zero tracking is turned off and will have to be addressed. It may be addressed by changing the configuration parameter of the zero tracking to have it activated. Of course this requires that one have the technical data to have the ability to change this parameter. If not, then the zero error will have to be addressed in the same manner as determining the weighing element error at load condition. Example: it is determined that the weighing element indicates 0.050 kg high at zero. Then at load, the weighing element indicates 0.100 kg high. Effectively, the error at load is 0.050 kg high. Another way to say this is the effective error at load is equal to the error at load minus the error at zero. 0.1 –0.05 = 0.05


The indication remains 80.0 kg

What we are looking for here is what amount of fractional mass is required to bring the indication into the zone of uncertainty? If the zone is very narrow, you may see the indication increment upwardwithout any flickering. Under ideal laboratory conditions a fractional mass value of 1/10 of the weighing element increment may be used, as environmental conditions are precisely controlled to allow for this. However, in the field where environmental conditions are as they are and uncontrollable, ¼ of the weighing element increment will be sufficient. Although as mentioned previously, efforts should be made to protect the weighing element from environmental conditions anyway, so that stable readings may be obtained when performing the verification on the weighing element as well as when performing the tolerance tests on the dispenser.


Fractional mass increased to 0.300 kg and the indication increases to 80.5 kg

The fractional mass value required to achieve entry into the zone of uncertainty is the fractional mass value we use to determine the weighing element error. As a point of note, most digital weight indicators of recent times will have a very narrow zone of uncertainty so that you may not see it at all. In this case the fractional mass value required to cause the display to increment upward to the next indication will be the value used to determine the error.

For the purpose of tolerance testing the dispenser, we should calculate the weighing element error in kg so that we may apply this error directly to the values of gross and tare (as opposed to calculating the error in fractions of the increment, which would require the additional step of converting the error back into kg).

Weighing Element Error Weighing Element Error

The weighing element is 500 kg x 0.5 kgThe weighing element is 500 kg x 0.5 kgThe standard mass on weighing element is The standard mass on weighing element is 80 kg, the display is 80.0 kg80 kg, the display is 80.0 kgThe fractional mass required to enter the The fractional mass required to enter the zone of uncertainty or increment the display zone of uncertainty or increment the display to 80.5 kg is 0.300 kgto 80.5 kg is 0.300 kg

To keep our errors in kg we use kg values in the formula. As opposed to calculating the error in fractions of the increment.

Error = Indication + (0.5 x increment value) Error = Indication + (0.5 x increment value) ––Fractional Mass Value Fractional Mass Value –– Standard LoadStandard Load

Error = 80.0 kg + (0.5 x 0.5 kg) Error = 80.0 kg + (0.5 x 0.5 kg) ––0.3 kg 0.3 kg –– 80.0 kg80.0 kg

Applying the formula, the error is determined Applying the formula, the error is determined to be to be --0.05 kg0.05 kg

Weighing Element ErrorWeighing Element Error

Therefore, 80 kg + 0.25 kg – 0.3 kg -80 kg = -0.05 kg. Remember, these examples assumed a zero error at zero load.

Therefore, the correction would be to add Therefore, the correction would be to add 0.05 kg to the indicated value of the test draft 0.05 kg to the indicated value of the test draft (at 80 kg)(at 80 kg)

Weighing Element Correction Weighing Element Correction

Remember, the correction is always in the opposite direction as the error. In this case, the weighing element is under registering so we must add this value back into the numbers we will see during the actual test because this is the actual value of the mass on the weighing element. It is like the weighing element is telling us “I am under registering, so add my error to the display to achieve the true value of what is sitting on me”.

Weighing Element Correction Weighing Element Correction

Values of over Values of over registrationregistration

I am over registering, subtract my error from the display to achieve the true value of what is sitting on me!!!

Of course the opposite is true in the case of an over registration. The weighing element would say “ I am over registering, so subtract my error from the display to achieve the true value of what is sitting on me”.


Determine error at tare loadDetermine error at tare load

Determine error at gross loadDetermine error at gross load

The purpose of determining error at both tare and gross is due to the fact that during the actual tolerance testing of the dispenser, we will do a corrected net calculation to obtain the weight of the draft.

33


Repeat this procedure to include loads above Repeat this procedure to include loads above and below the target tare and gross loads and below the target tare and gross loads

Typically, this procedure is the same as conducting increasing and decreasing load tests at load values of 1500 to 2000 divisions in increments of 500 divisions above and below the target tare and gross values (three to four test points above and three or four test points below target). This may require a trial run of weighing the cylinder empty to obtain the tare weight, then filling the cylinder to see what your target gross values will be. The reason for choosing 4 points above and below the target tare and gross is because the cylinder will not always be emptied to the exact same tare value every time. Therefore, your gross values for a full cylinder will not be exactly the same on subsequent drafts.


Repeat complete procedure to verify Repeat complete procedure to verify repeatability of weighing elementrepeatability of weighing element

Whatever your target values or tests points for the weighing element verification are, they should be performed two to three times. Conducting the procedure in this way tells you if the weighing element repeats or gives the same results for the same target weight values. In reality you may not repeat errors of the weighing element exactly for each of the three increasing/decreasing load tests and this is normal due to environmental conditions. However, the errors should repeat within a couple tenths of each other. It is acceptable to average the errors for each load. If you see excellent repeatability (exactly the same errors), it is acceptable to conduct only two increasing/decreasing load tests.

Weighing Element CorrectionWeighing Element Correctionas Applied to Tolerance Testingas Applied to Tolerance Testing

Corrected calculated net value of CNG = Corrected calculated net value of CNG = Corrected gross Corrected gross –– Corrected tare Corrected tare

Let’s say we have a gross values of 92.00 kg and a weighing element error of minus 0.70 kg. The corrected gross value is 92.70 kg. The tare value is 72.00 kg and a weighing element error of plus 0.30 kg. The corrected tare value is 71.70 kg. Therefore the corrected net value is 21.00 kg. I am sure that some of you may have already noticed that there is another method to derive the corrected calculated net value. You may use the actual gross and net values you see on the weighing element and calculate the net value. Then apply the same method discussed earlier in regards to applying the zero error at load. Again, the error at the gross load is minus 0.70 kg and the indication is 92.00 kg. The error at tare load is plus 0.30 kg and the indication is 72 kg. Therefore 92 kg minus 72 kg equals 20 kg net load. Now, the error at gross load (-0.70 kg) minus the error at tare load (+ 0.30 kg) equals minus 1.00 kg. So you would add 1.00 kg to the net value of 20 kg to derive a corrected net value of 21.00 kg. Either one of these methodologies may be applied to derive the net load of the draft, AS LONG AS YOU KEEP THE SAME METHOD THROUGHT YOUR PROCEDURE!!!

Preliminary Preliminary –– data from weighing element data from weighing element verificationverification

We have established the weighing element corrections for all the tare and gross values that may be applied. Now, we apply the corrections to the actual weight values we see during the delivery of product into the cylinder for the performance part of the test. Remember, corrected gross minus corrected tare equals the calculated corrected net delivery.


Record tare weight of Record tare weight of cylindercylinder

Start with an empty cylinder. This will be indicated on the pressure gauge and anything below 1379 kPa (13.5 bar) will be considered empty. At this time make necessary correction to the tare weight and record the corrected tare value.

40


Start dispenser and Start dispenser and proceed to fill the proceed to fill the cylinder. cylinder.

At this time, you perform several tests at once. When you start the dispenser, verify the zero starting position of the display and that the zero is displayed correctly. That is all zeros to the left of the decimal and at least one zero to the right of the decimal. Verify the zero starting position for both mass and total sale. You may also verify the increment of the mass value to 0.001 kg and verify the unit price display. Record the totalizerreading to be compared with the final draft for correct cumulative recordings. The flow rate may be viewed by manipulating the transmitter display or other controls on the dispenser for verification that the dispenser is operating within the parameters of the measuring element.


Record gross weight of Record gross weight of draft when fill is draft when fill is completedcompleted

At the completion of the fill, disconnect the hose from the cylinder and record the gross weight. Make the necessary corrections to the gross weight and record corrections.


Record end Record end totalizertotalizerreadingreading

Record end totalizer reading to check the cumulative value of the totalizerin succession at the end of each tests draft.

times 100times 100

Error = Error = indication indication –– mmcc

mmcc X 100X 100

The delivery error is calculated by subtracting the corrected gross weight from the corrected tare weight to result in the corrected calculated net weight. Subtract the corrected calculated net weight (standard) from the dispensers indicated delivery. Divide the results by the corrected calculated net weight (standard) and multiply by 100 to obtain the results in percentage. Meter minus the standard divided by the standard times 100 equals percent error of indicated delivery.

41


Check the zeroCheck the zero--setset--back interlockback interlock

Check the function of the zero-set-back interlock. A device shall be constructed so that:after a delivery cycle has been completed by moving the starting lever to any position that shuts off the device, an automatic interlock prevents a subsequent delivery until the indicating elements, and recording elements if the device is equipped and activated to record, have been returned to their zero positions;the discharge nozzle cannot be returned to its designed hanging position (that is, any position where the tip of the nozzle is placed in its designed receptacle and the lock can be inserted) until the starting lever is in its designed shut-off position and the zero-set-back interlock has been engaged; andin a system with more than one dispenser supplied by a single pump, an effective automatic control valve in each dispenser prevents product from being delivered until the indicating elements on that dispenser are in a correct zero position.


Check receiptCheck receipt

At this time you may also compare the printed receipt to the dispenser indications (total delivered amount, unit price, total sales price, and the product identity (by name, symbol, abbreviation, or code number). Additional receipt requirements such as a receipt identification number, time, date, and the name of the seller shall also be printed. The printed values must be identical to the indicated values.


Return Return product product to storageto storage

Our requirements are that the site have provisions to return the product to storage. CNG is non toxic and poses no health risks unless you are in a confined space (confined spaces causes asphyxiation), it dissipates in the atmosphere. However flammability limits are a concern, so venting to the atmosphere has been prohibited. In the past we have allowed representatives of the gas supplier to use vent stacks (at least 4 meters in height) to vent to atmosphere, but this practice is being discontinued. In any case (product venting or returning to storage) we as weights and measures inspectors do not handle the gas. We have a representative of the gas supplier, owner/user, or station maintenance personnel handle the gas. You must check with your local jurisdictions regarding these requirements. Provisions to return the product storage is a user requirement, not a device requirement. When enforcement action is necessary, typically the device owner will have the gas supplier or the dispenser manufacturer add plumbing to either the main gas supply or the compressor phase.


Prepare for next Prepare for next deliverydelivery

While the product is being returned to storage, this is a good opportunity to verify the functional requirements of retaining the last transaction. The total price and quantity delivered shall be displayed on the face of the dispenser for at least 5 minutes or until the next transaction is initiated.

42


Repeat the previous delivery performanceRepeat the previous delivery performance

Tests for repeatability should include a minimum of three consecutive test drafts of approximately the same size and be conducted under controlled conditions where variations in factors, such as, temperature pressure and flow rate are reduced to the extent that they will not affect the results obtained. When multiple tests are conducted at approximately the same flow rate and draft size, the range of the test results for the flow rate shall not exceed 40 % of the absolute value of the maintenance tolerance and the results of each test shall be within the applicable tolerance. U.S. requirements for maintenance tolerance is 2% therefore our results for repeatability should be 0.8% or less. This means that all drafts should be within 0.8% of each other such that if one test is minus 1.5% and the next test is minus 0.7%, the device is at the tolerance limit for repeatability.

Sealing RequirementsSealing Requirements

Sealing provides for Sealing provides for securitysecurity

U.S. requirements allow U.S. requirements allow for three categoriesfor three categories

In the U.S., there are three categories for sealing. They are: Category 1: No remote configuration capability sealed by physical seal or 2 event counters: 1 for calibration parameters and 1 for configuration parameters. Also refer to handout NCWM Publication 14 Appendix A.


Category 1 exampleCategory 1 example

In this example, the manufacturer hard coded all the configuration parameters into an E-PROM (erasable programmable read only memory) that had to be removed and sent back to the manufacturer for reprogramming, so there is no remote configuration. Due to the fact it is located inside the dispenser under a control panel, in proximity of other electronics, a self-destruct tamper evident paper seal is used.


Category 2, Category 2, remote remote configuration configuration exampleexample

In this example the transmitter has remote access but controlled through the position of a switch that is under a physical seal.

Category 3: Remote configuration capability access may be unlimited or controlled through a software switch (e.g., password). [Nonretroactive as of January 1, 1995]The device shall clearly indicate that it is in the remote configuration mode and record such message if capable of printing in this mode or shall not operate while in this mode.[Nonretroactive as of January 1, 2001]Nonretroactive as of January 1, 2005, all devices with remote configuration capability must comply with the sealing requirements of Category 3. For sealing Category 3 an event logger is required in the device; it must include an event counter (000 to 999), the parameter ID, the date and time of the change, and the new value of the parameter. A printed copy of the information must be available through the device or through another on-site device. The event logger shall have a capacity to retain records equal to 10 times the number of sealable parameters in the device, but not more than 1000 records are required. (Note: Does not require 1000 changes to be stored for each parameter.)

1- History

-1964 Establishment of the National service of Weights and Measures, under the Ministry of Industry. -1975-79 No activities. -1995 Re-Establishment of Weights and Measures Unit, under the Ministry of Industry, Mines and Energy (MIME). -1999 The Weights and Measures Unit upgraded to the Department of Metrology. -2000 Corresponding member of the International Organization of Legal Metrology (OIML). -2002 Member of Asia Pacific Legal Metrology Forum (APLMF).

2- Structure of Metrology Recently, the Metrology of Cambodia is split between the Department of Metrology

(DOM) and Industrial Laboratory Center of Cambodia (ILCC). DOM has the responsibility for all Legal Metrology Activities and keeps the Secondary

and Working Standards. ILCC keeps the Primary Standard and also implements the Industrial and Scientific

Metrology requested by DOM. Our structure is as below. 3- Organization Chart

Note: -DoM acts as the Legal Metrology Body. -DoM maintains and keeps secondary and working standards. -ILCC keeps primary standards and implements scientific, industrial metrology requested by DoM.

4- Presentation the Non-LPG Fuel Dispensers situation 1-1- My name is SEA Kimhoun. I work as an Inspector of Department of Metrology

(DOM), Ministry of Industry, Mines and Energy (MIME). Presently, my position is Chief of Control and Verification Office in charge of verification and inspection of all kinds of weighing and measuring instruments.

1-2- I need train the others. Some time, I have to train also for provincial verification officers.

1-3- Yes. I have some experience verifying fuel dispensers for petrol (every types of dispensers: for example gasoline and D.O...). The most dispenses are automatically and mechanical.

The procedure is as below: A- Visual Inspection A-1- Required Data:

To record the date of test, registered trading name, the mark, model, pump number. A-2- Assessment of Fuel Dispensers: A-2-1- External inspect the Fuel Dispensers:

To check the fuel dispenser is firmly fixed on its foundation, all indications are visible under conditions day and night, nozzle must terminate the delivery …. A-2-2- Internal inspect the Fuel Dispenser:

To check the apparent leaks at the pump, hose, meter, gas elimination device, the components are located and fitted in accordance with the certificate and verification mark and seals are in place …. B- Performance Tests:

- Volume for testing is 05 litre. - Display of indicator of Fuel Dispenser is compared with Working Standard Vessel - The MPE is +/- 0.5%.

46

5- Current situation about Verification of CNG Fuel Dispensers

Why not the CNG Fuel Dispensers are verified? While there are more than 200 Non-LPG stations and more than 200,000 vehicles in the

country, there are less than 7 LPG stations recently installed and about 100 vehicles mostly taxis vehicles are powered by LPG. They sold LPG to the public without limitation by volume. We don’t know the method and the equipment requirements for the implementation of the measuring system.

DOM will regulate and verify of Non-LPG and LPG. We performed the verification by gravimetrically (by weighing).

The subject of the CNG Fuel Dispenser has not implemented yet. It is new subject for my economy, but we hope to carry out in the future. 6- Conclusion

Cambodia has opportunity as a member of APLMF and always received support technical and financial assistance from the APLMF executive secretary and all friends’ members made Cambodia upgrade herself to participate in the regional and international metrology activities.

On behalf of DOM, Cambodia I would like to express my gratitude to APLMF and APEC secretariat and the host country for their sponsorship and organizing this training course.

Thank you for your kind attention.

“ Training courses on CNG Fuel Dispensers in Shah Alam ,Malaysia on June 27 – 30 , 2006 ”

Country Report on CNG Fuel Dispensers Activities in Lao PDR

Presented: By Mr. Kadingthong Singdala Metrology Division

Department of Intellectual Property, Standardization and Metrology(DISM),

Science, Technology and Environment Agency(STEA).

61

Chairman. Distinguished Ladies and Gentlemen,

On be half of Lao PDR I’m very Pleased to be here with you to present some information on the activities for the Metrology Management in Lao PDR

I would like to express my sincere thank to the all of organizers for assisting and providing us the opportunity to participate to the Training Course on CNG Fuel Dispenser in Shah Alam, Malaysia. I. Basic Country Data.

The Lao People’s Democratic Republic ( Lao. PDR ) is a land-locked and mountainous country which borders China to the north, Cambodia to the south, Vietnam to the east, Thailand to the west and Myanmar to the northwest. Lao PDR has a total area of 236,800 square kilometers with a population of 5 million ( 1998 ),it’s capital is Vientiane. The Lao PDR was established on December 2,1975. The climate is tropical and dominated by the southwest monsoon which brings high rainfall, high humidity and high temperatures between mid-April and mid October. While over 70% of the rain falls during wet season, the climate is characterized by high inter-annual variability with relatively frequent occurrence of flooding and drought. Average temperatures ranges around 20•c in the mountainous areas and on the highland plateaus to 25•c - 27•c in the plain. Gross Domestic product ( GDP ) per capita: 380 US$ ( 1997 ). Trade and Current Account Balance Deficits:

While imports have been increasing with growth, exports have been subject to fluctuations caused by variations in world prices ( fuel or coffee for example ).Export policy is generally given more attention than import policy , although the value of import is two or three times the value of exports. Export are mainly of garments, electricity, timber, wood products, coffee, cardamom, mining output, and forestry and agriculture products. Import of food have generally declined, but imports of factory raw materials, and vehicles, agricultural equipment and machinery have increased. Raw materials make up 63% of all imports. The biggest import drain on hard currency in 1999 was fuel, costing US$ 70 million. Vehicles, machinery, raw materials, garments, construction materials, pharmaceutical products and food followed this. Up to now, the imported goods except drug and food are not controlled and inspected by any concerned bodies yet. II. The Present Status And Problems on the activities of Fuel Dispenser in Lao. PDR.

Organizational Chart of DISM ( see annex1 ). Organizational Chart of Metrology Division (MD) ( see annex2 ).

62

Department of Intellectual Property, Standardization and Metrology ( DISM ) under Science Technology and Environment Agency ( STEA ) are a National Standards Body ( NSB ) and a Government Body . The DISM was established in 1993 under STEA, which advises and manage the issues of intellectual property, standardization and metrology management for the whole republic. The main priority task of DISM is to improve standards and quality awareness in all economic sectors as to:

♦ Prepare plans, law, rules and regulation on QSTM and submit them to the higher authorities for approval;

♦ Organize the supervision and central on the implementation of the approved law, rules and regulations;

♦ Establish organization system on QSTM and provide methodological guidance for all activities of the above system;

♦ Organize formulation of national standards and maintain national metrology standards; ♦ Provide and implement quality system and product certifications, testing and calibration,

verification of metrology equipment and laboratory accreditation. Implement the supervision and inspection on quality of goods and products and measuring instrument;

♦ Conduct studies on QSTM; ♦ Improve the technical level of employees, training and cooperate with regional and

international organizations in the field of QSTM management.

The local management agency ( Provincial and Municipal level ) has the role in activities regarding QSTM matters as well as central activities but according to the recommendation of the central management agency. Legislation : In order to ensure and strengthen administration of QSTM matters, Lao PDR has promulgated some necessary legislation relating to the standardization, quality and testing metrology management are the following : ♦ Decree on Metrology Management issued by the Prime Minister in October 26,1993. ♦ Regulation on Registration of Measurement Instruments ( No 233/STEA. March 10,1994 ). ♦ Guidelines on Registration and Testing of fuel Dispenser(February 07,2001). ♦ Regulation on Prepackages goods (Drafted) ♦ Regulation on Fuel Truck Tank registration (Drafted)

However, all legislation mentioned above are relating with some activities of the management only, but still absence of the right inspection and testing system with Legal Metrology conformance .

63

CNG Fuel Dispensers Activities in Lao .PDR:

Regarding the fourteen questions asked me about the activities on CNG Fuel dispensers, they are only the part I which we have the activities on it. Others parts such as part II and III we haven’t yet.

As you know Lao PDR is a land lock country and no sea and no oil sources at all. Therefore CNG Fuel is a new matter for Lao and I frankly said that we have no any experience on it. And I am pleased here and be happy that APLMF and NIMJ who have gave me the opportunity to be here and get experiences and lessons on CNG Fuel on how do they perform or control on both theory and pratice in this field .many countries in the world now they are seeking for the alternative source like CNG to replace petrol as currently the price is increase days by days . we also are seeking to find the way out and it is under our responsible on how to control ,perform and used in reality .

As I have mentioned Metrology division is under the department of Intellectual Property Standardization and Metrology and we had experience only on Petrol and LPG Fuel dispensers and not CNG Fuel dispensers yet . Also some experience on the accuracy testing of weighing for a year and the class range from class I to IV. And in general to perform the activities on metrology we have based only the Decree on Metrology Management issued by the Prime Minister in October 26,1993 and the Regulation on Registration of Measurement Instruments ( No 233/STEA. March 10,1994 ).

Finally on behalf of myself, I would like to express my sincere thank the government of Japan particularly National Institute Metrology of Japan who has supported me even it is not fully due to lao current situation condition I still have felt happy to be part of this meaningful training course and also many thanks to all of organizers who had a good relationships in contacting and facilitating me before and during the training course. And I thank a lot to all of my colleagues participants in this training courses who have always assisted and gave me their experiences without limitation during the course.

Thank you for your patience attention.

National Metrology Laboratory of the Philippines -Industrial Technology Development Institute (NML-ITDI) I. The NML-ITDI

The mission of the National Metrology Laboratory is the establishment, maintenance and dissemination of standards of units of measurements.

The NML-ITDI is the organization responsible for establishing and

maintaining national physical standards for basic and derived quantities such as mass, length, temperature, volume, force, time interval, voltage and resistance. Dissemination of standard values to users at the best uncertainty levels attainable is performed through the calibration and measurement services offered by the laboratory.

I.I. Metrology Services Offered by the NML-ITDI

The NML-ITDI is equipped with high precision standards and measuring instruments for use in its calibration and measurement activities. National standards are regularly calibrated abroad to ensure international traceability.

NML-ITDI has five major labs, which keep and maintain the national standards in the different fields of metrology. Each of these laboratories disseminates the standard units of measurement through our calibration services. 1. Volume/Density/Viscosity/Moisture Standards 2. Mass Standards (Force and Pressure Standards) 3. Length and Engineering Metrology Standards 3. Electrical/Time/frequency Standards 4. Thermometry and Hygrometry Standards

Each of these laboratories disseminates the standard units of measurement through our calibration and testing services. Our clientele include hospitals, schools, manufacturing companies and calibration laboratories. I.II. Metrology Training Center

The NML-ITDI has three on-going programs to help us develop and strengthen a pyramidal metrology infrastructure appropriate for the country.

One of these programs is the Metrology Training Program. Through the Metrology Training Center, we conduct on-site trainings and

in-house trainings on metrology. On-site trainings are trainings conducted at the premises of the requesting company while in-house are trainings conducted at the ITDI.

Trainings offered usually last for 3 days with lectures and laboratory work.

The MTC Project has served 170 participants from various sectors such as the

80

academe, private calibration laboratories, food manufacturers, traders of agricultural products, manufacturing industries, industrial equipments, etc.

As part of our service obligation when sent to trainings abroad, metrology

staffs are also given a directive to conduct technical forums on the trainings we have attended.

NATURAL GAS INFRASTRUCTURE IN THE COUNTRY I. USE OF CNG IN THE PHILIPPINES: I.I. Natural Gas Vehicles (NGV’s)

There are about 12 NGV’s here in the Philippines with another 200 privately-owned units expected to be delivered from China by August 2006. ♦ The Philippine government currently owns about 12 units of CNG Vehicles. 2 demo units of these are owned by the Department of Energy (DOE) and acquired form Korea and India. The other 4 are NGV’s converted by DOE and are undergoing further testing. The Philippine National Oil Company (PNOC) owns 6 Original Equipment Manufactured taxis from Petronas, Malaysia These NGV’s have undergone on-road testing to asses the technical viability to local conditions. They are also used to inform and educate the people of the benefits of NGV’s . ♦ The 200 NGV’s are owned by several accredited transport groups with

provincial routes plying near the Malampaya onshore gas plant . The 200 public utility buses (PUBs) are low-emission buses powered by Cummins Westport engines.

Use of CNG in the public transport will increase with the arrival of the 200 PUBs. The national government, with its policy to promote the Clean Air act through use of environmentally friendly fuels, has launched the Natural Gas Vehicle Program for Public Transport (NGVPPT) aiming to convert public transport vehicles such buses, taxis and jeepneys to run on CNG.By offering incentives, income tax holidays and providing preferential franchise, the government in encouraging more public transport operators to use natural gas as fuel alternative. I.II. GAS SUPPLY-CNG REFUELING STATIONS

There are currently 3 refueling stations constructed in the country. ♦ Gas supply from the San Antonio, Isabela Gas field

The first and only operational refueling station is the PNOC-Exploration Corporation’s CNG Refueling Station in Echague, Isabela. The gas supply is from the San Antonio, Isabela Gas field. This station was constructed initially to supply the 12 demo units owned by Doe and PNOC. ♦ Gas supply from the Malampaya Gas field

A mother-daughter refueling system is constructed to transport natural gas from the Malampaya Gas field . The CNG mother station is located within the Malampaya on-shore gas plant in Batangas with the daughter in Batangas City. The mother station serves the CNG requirements of the daughter stations, which in turn will supply the gas needs of the above mentioned 200 CNG-fed public utility buses.

82

The Natural gas supplied by the Malampaya gas field is to be utilized by the public transport sector and gas powered plants I.III. (POTENTIAL) GAS DEMAND AND MARKET Power Generation

Gas demand comes mainly from the power sector. Gas from Malampaya is used to fuel three power plants in Batangas with a

combined capacity of 2700 MW. These power plants are the 1200 MW CCGT Ilijan Power Plant, the 500 MW San Lorenzo Power Plant, and the 1000 MW Sta. Rita Power Plant. Industrial Sector (Potential)

Industries along the proposed pipeline routes linking Batangas province and the Bataan peninsula to Metro Manila are expected to be a natural gas market. Natural gas will be used for their process heat, air conditioning and power requirements. Commercial and Residential Sector (Potential)

Gas can be an alternative to electricity for their air-conditioning and lighting use. Principal opportunity for gas use in the residential sector is as a replacement for LPG as a cooking fuel. II. LEGAL METROLOGICAL CONTROL ON CNG DISPENSERS IN
