TEST CERTIFICATION NO GB-1285 Revision 4

Descriptive Annex 1 Introduction The EMR³ meter register is an electronic calculating / indicating device for interruptible systems for measuring liquids other than water with an accuracy class 0.5. The EMR³ system is suitable for use with any compatible approved meters.

(Note: the last digit x on the part number represents the front panel overlays in other languages, e.g. 3 English, 2 French, 4 Spanish) 2 Description The EMR³ system comprises of the Register Head (display), the Interconnect Box and an optional printer. The system works in conjunction with a flowmeter in order to provide accurate measure of liquid deliveries and also to control the liquid flow process and to print priced receipts. It is designed to operate with either a 12V or 24V dc electrical supply system. 2.1 EMR³ Register Head (Display) Electronic pulses from the meter may be passed to the EMR³ register head, or it may be fitted with an optional internal pulser unit mechanically linked to the meter. The register head processes the pulses, converting them into volume using stored calibration values. The unit may also calculate the cost and tax of the delivery. An external keypad may be fitted as shown in figure 1. Up to the last 20 transaction records may be stored in non-volatile memory located in the display head. The results of the delivery are displayed on the register head display and may also be printed on a remote printer. The Head may be fitted with an optional alphanumeric keypad for ease of data entry. A mode switch toggles the register head display between the volume, rate of flow and price (where specified) information.

Temperature compensation may also be implemented using an optional temperature probe. An approved temperature correction algorithm is stored in the EMR³ for automatic correction when in the temperature correction mode. 2.2 EMR³ Interconnect Box (IB) The Interconnect box provides intrinsically safe power to the register and also controls the interface between the register and the rest of the measuring system (figure 2). One IB can operate two display heads and up to 16 IB’s can be connected together to form the EMR³ IB network. The IB has memory storage for the last 200 transactions in non-volatile RAM, 20 of which are duplicated in each Register Head. Internal relays may be employed to interface the system electronics to external pneumatic or electromagnetic valves, for example controlling the fluid flow or pre-set devices. 2.3 Pulser The internal pulser is an optical pulser manufactured by Oak Grigsby (USA), part number 94Q100-B3-00350, Bourns type ENS1J-489-L00100 part number 331884-001, Digital HEDS-9100-C000 type E2-100-375. Other internal or externally mounted pulse encoders or direct pulse inputs may be used that have been issued with a test certificate by a Notified Body responsible for Annex B (MI-006) under Directive 2004/22/EC. An externally mounted pulser is shown in Figure 7. 2.4 Electronic Temperature Probe (figure 3) This is a two-wire thermistor which is used as an associated measuring instrument. It is manufactured by US Sensor Corporation and has part number USP2119. Other temperature probes may be used in place of the above thermistor provided they meet the accuracy requirements of OIML R117 paragraph 2.7.2. NOTE: PT100 type temperature probes will not operate with the EMR³ system. 2.5 Printer A printer may be fitted as an option. The printer is typically an Epson TM-U295 slip printer (figure 4). It is used for printing delivery tickets showing the date and time of a delivery, the ticket number, the quantity delivered, the price and other operator entered details. The nature and format of the ticket record is set up using the Register menu system. Any simple recipient printer may be used in place of the Epson TM-U295 printer provided:

i. it bears the CE mark for conformity to the EMC Directive 89/336/EEC;

ii. it is not capable of transmitting any data or instructions into the EMR³ other than for releasing the printout, checking for correct data transmission;

iii. it prints delivery results and other data as received from the EMR³ without any modification or further processing.

2.6 Pre-set Device (Figure 5) The EMR³ can be configured with an optional pre-set device for dispensing a specific amount of fuel either by volume or price. The pre-set mode is selected by the “PRESET” button on the front panel, and the pre-set amount is chosen by using the “NEXT” & “+/-“ keys. When the fuelling starts the pre-set amount shown on the display counts down. During a dispensation the pre-set can be altered, overridden or cancelled thus allowing the tank to be ‘topped off’. The whole operation is controlled by two trigger relays in the IB unit to enable a two-stage valve cut off procedure. i.e. normal fast dispensation – both relays open; first stage cut-off (slow fuelling) – one open and one closed; flow stopped, both relays closed. These first and second stage cut off relays may be pre-programmed to deactivate depending upon the characteristics of the particular valves used and their delay time. 3 Operation Pricing and set-up information are entered into the Register Head using the Head keyboard or the optional alphanumeric keypad. When START is pressed, the Interconnect Box outputs signals to various components of the system to control their integrated operation. The rotary motion of the flowmeter is transformed into electrical pulses by the pulser mounted inside the Head (or externally). The Head converts these pulses into volume using the stored calibration data. At the same time, it corrects the volume to standard temperature if the temperature correction mode is enabled. When the desired quantity of liquid has been measured and if the preset mode is enabled, the Head signals the Interconnect Box to stop the liquid flow by operation of internal relays which in turn operate electromagnetic or pneumatic valves. Alternatively, pushing the FINISH button causes the relays to de-energise, thus stopping the flow. On completion of a delivery the transaction is stored. If the ‘enable printer’ function is enabled, a printout is produced when the FINISH button is pressed. On pressing the FINISH button a second time the register is reset to zero and the unit awaits the start of the next fuelling.

7/13

4.2.3 Software security

Recalibration and the amendment of calibration constants, labels, etc, may only be done when in the EMR³ Register Head is in the C&C mode. Entry to the C&C mode for amendment is accomplished by opening a microswitch housed inside the sealed Register Head. Alternatively, the microswitch may be replaced by inserting a wire link in the terminal block also inside the Head.

4.2.4 Checksum Identification

For Register head version F09 the checksum 0000F8d0 is also displayed at start up.

5 Adjustment and Securing (Sealing)

5.1 Calibration Factor

Calibration is effected in the C&C mode and may be performed manually or automatically. Additionally, calibration may be carried out at each of 8 different flow rates. The number entered scales the pulses for the volume metered. After calibration, this number cannot be altered without breaking the seal on the Register Head.

5.2 Error threshold

The error threshold MODE M2 is adjusted whilst in the C&C mode. This must be set to a maximum value of 250.

5.3 Temperature correction

The temperature correction algorithm is stored in the Register Head and is not accessible by normal means. The temperature probe is calibrated at 0°C via the C&C mode with the probe immersed in a water/ice mixture. After calibration, this setting cannot be altered without breaking the seal on the Register Head.

5.4 Sealing (Securing)

5.4.1 The securing mark may be either:

- A mark of the manufacturer and/or the manufacturer’s authorised agent, or

- An official mark of a verification officer.

5.4.2 The retaining screws securing the Register Head to the flowmeter are drilled through. Wire may be passed through these holes, brought together and an approved seal applied.

5.4.3 Where a remote pulser and remote display are used, the pulser itself or the pulser interfacing plate screws are drilled to take the sealing wire, which will depend upon the flowmeter configuration. The screw lid of the remote pulser unit requires sealing as shown. The Interconnect Box is secured with a seal through the lid.

8/13

5.4.4 An optional variant is permitted whereby the calibration control (C&C set-up) mode is accessible on the front panel of the display unit. To prevent unauthorised adjustment, a metal knurled threaded cover is screwed over the adjustment control. This cover is secured in position by passing a sealing wire through a pre-drilled hole in the cover and running it via pre-drilled holes in the heads of two adjacent panel securing screws. The wire ends are drawn taught and sealed with an approved seal (figure 6).
