About this Manual

All aspects of the Magnum flowmeter are controlled by software, so it made

sense to also "digitize" the operating manual for this instrument as well. Since the

operation of this flowmeter is actually quite simple and straight forward we evenconsidered that the Magio software itself serve as a kind of interactive manual. In

some respects it clearly does this, but there are some issues concerning the

hardware and installation that are not discussed in the software and for which this

"visual" manual is intended and far better suited..

The hypertext format was chosen because of the familiarity of most Computer

users with the Internet browser interface, readily available software in the form

of Netscape and Explorer and other browsers, and the possibility of incorporating

multimedia in this manual.

For those more comfortable with a printed manual it is of course also possible

to produce hard copies of the information contained herein.

Components

The Magnum Flowmeter is made up of a sensor, transmitter,

mounting mechanism and cables.

The Sensor is usually mounted inside the universal mounting

mechanism (Universal for short) ready for installation. The

sensor consists of a 1.5" 316 stainless steel tube, which

houses the magnetic coil. The KYNAR or PEEK end-piece

closes this tube at the end which is inserted into the liquid.

The Hastelloy or 316 SS electrodes protrude from the end-

http://www.magmeter.com/manual/trouble.html



http://www.magmeter.com/manual/repairs.html








piece and pick up the voltage, i.e. signal produced by the movement of the

conductive liquid through the magnetic field generated by the magnetic coil. The

cable which leads to the transmitter portion of the Magnum is sealed into the

other end of the sensor.

The Universal allows the attachement to and insertion into any pipe through a 2" NPT tap and ball-valve. The Universal consists of several parts. The threaded

body (anodized aluminum), the nipple (316 stainless steel), which connects to the

ball-valve of the 2" tap, and fitted with a ball bearing mechanism permitts free

rotation of the sensor and upper part of the mounting mechanism. The nipple also

contains 2 o-rings of different materials depending on the application, which seal

the sensor and the outside world from the line pressure inside the pipe. Two nuts

(anodized aluminum) are used to insert the sensor, hold it in place against line

pressure, and lock it into position.

The Transmitter consists of

an anodized aluminum

NEMA 4 enclosure. It

houses the digital electronic

boards which drive the

magnetic coil of the sensor

and process the information

it receives. A 128 x 128

pixel graphic display is

mounted on the front of the

transmitter. Two 5-pin

connectors on the left side

of the transmitter provide access for the sensor cable and the PC/Magio interface

cable. The 10 pin connector on the right-hand side of the transmitter receives

power-in (12-24V DC) and provides signal outputs (4-20mA, RS232, pulse,

alarm). A standard of 10 metres of 2 pair separate shielded cable connect the

sensor and transmitter. The maximum length of this cable may not exceed 50

metres.

The PC interface cable allows connection of the Magnum transmitter to any IBM

based PC via an available serial port. The Magio 3.0 interface software is

required.



IMPORTANT NOTE : The sensor, cable and transmitter of the Magnum are

integral and matched. The sensor will not function without the transmitter. It will

also not function accurately without the exact transmitter and cable with which it

was originally calibrated. The sensor-transmitter cable is part of the flowmeter

calibration. It may not be cut or modified or the Warranty will become void! To

change cable length for a particular application the instrument (Sensor, cable andtransmitter must be returned to the factory.

Basic Operating Principles

The Magnum Magnetic Flowmeter determines the flow of conductive liquids in

pipes. It does so by determining liquid velocity using the the principle of

magnetic induction. A conductor (water, for example) moving through a

magnetic field generated by the Magnum flowmeter (see illustation) will generatea current that is proportional to the velocity of the conductor. The higher the

generated current, the higher the velocity signal.

The Magnum's digital electronics combines the velocity information with

existing information about the pipe size, and processes it based on user

preferences in regards to filtering and range information into a reliable

information about flow. It is important to keep in mind that Magnum is first and

foremost a device to measure velocity. It's ability to provide accurate information

about flow depends on a number of important outside factors that need always betaken into account:

- area of flow as determined by inside diameter of a given pipe needs to be

provided precisely.

- the pipe needs to be completely filled.

- flow in a given application should be fully developed turbulent flow with a

symetrical flow profile.



- the range (scale) chosen should be based on actual current flow and not future

capacity.

- if the electrodes are not fully submerged in conductive liquid measurement is

not possible.

Some allowance can be made for less then ideal application circumstances owingto the ability of the Magnum operating system to compensate if set up

accordingly and properly, and thanks to the fortunate fact that magmeters by

nature are linear in their measurement even if in error. If the above conditions are

met, the Magnum will provide the most accurate and reliable measurement of

any flowmeter technology.

Suitable Applications

Any conductive liquid flowing in a filled/pressurized pipe.

This includes:

Water

Effluent/Sewage

Pulp

Liquors (pulp and paper industry)

Slurries (mining)

Brine

SludgeAny liquid food product

Various chemical mixtures

Unsuitable liquids (due to low conductivity or insulating properties):

Petroleum products

Crude Oil

Vegetable or animal fats (grease)

Demineralized Water

Magnum is a velocity measurement system that relies on correct input data

regarding pipe dimension and a suitable application based on physical laws and

limitations. We cannot guarantee accurate measurement in all possible

applications or suitability for any particular medium (see also Warranty).

Choosing a Location

Magnum can be installed at any angle on

any pipe. On steel pipes a 2" tap is used,

while platic or concrete pipes require a

saddle arrangement. A vertical installation

(see photo) is most common, butdepending on available space and wether

or not air or foam could be trapped at the

top of the pipe an installation at an angle

or even horizontal may be advantageous.

In order to insure the best possible

measurement some locations are better

suited then others. First and foremost

make certain the pipe is actually full.

Pipes which lead from open bodies ofwater also often promote the building of vortices which interrupt the flow profile

and pull air into the system for some considerable distance. Significant amounts

of Air or air bubbles may interrupt the functioning of the flowmeter. The sensor

needs to be fully submerged in conductive liquid in order to function.

For up and downstream distance from obstacles the general rule of thumb for

most flowmeters is 10 pipe diameters upstram and 5 pipe diameters downstream.

These distances can be reduced the larger the pipe or the faster the flow in it. The

goal is to find a location in which the flow is fully developed and turbulent -

resulting in a very flat and symetrical flow profile. This is the most commoncondition in larger pipes, so they require less straight run on average.

Since there is no scientifically reliable way to positively identify the ideal

location some educated guess-work may be required. Try to choose an

installation location with as much straight run as possible. Avoid close proximity

to valves (especially butterfly-valves), ellbows, junctions with other pipes, and



water intakes from open bodies of water. Due to its configuration and size

Magnum is not much affected by what happens after the measurement location.

If you are certain that the flow profile is asymetrical consider using two or more

Magnum sensors mounted opposite from each other.

The 2" NPT Tap

The Magnum

Flowmeter is installed

on any given pipe

through a 2" tap. The

tap consists of a welded

2" nipple, a short

threadolet and a 2" NPT

full bore gate or preferably ball-valve.

The overall length of

this tap assembly from

the outside of the pipe

to the end of the valve

should not exceed 8

inches on pipes up to

50" diameter. If it is

less then 6 inches a

standard Magnum can be used on pipe sizes up

to 70" diameter.

The tap can be installed on a pipe while in operation using the hot-tapping

method (for hot-tapping equipment suggestion click here). The tap is welded to

the pipe first, and the hole drilled afterwards with a special sealed drill through

the open valve. The valve is closed, the drill removed and Magnum inserted

instead without having to shut down the pipe during any part of this process.

On concrete or plastic pipes a so-called saddle is used to seal and fit a regularsteel/bronze tap for the insertion of Magnum.

Wiring

All wiring of the standard Magnum flowmeter is done

through the 10 pin connector on the right hand side of

the transmitter. By removing the cover from the

detacheable portion of the connector the user has access

to heavy duty screw-type terminals to connect power

input, signal output and a variety of external equipment.

The MAGIO 3.0 software at one point uses a wiring

diagram as seen below on the left. This is intended for the new Magnum IC

model flowmeter which is not yet in production. Instead use the wiring diagram

on the right, intended for the standard Magnum which also corresponds to the

connector seen above.



The sensor cable is lead to the transmitter through an 8 pin round connector on

the left side of the transmitter casing. Also on the left side is the 5 pin round

connector for the serial port/PC interface cable.

Your flowmeter is now operational.

MAGIO 3.0

Interface software for the Magnum digital flowmeter

Magio 3.0 is a Win95/98 native interface for the new Magnum flowmeter. It is

based on the original DOS based Magio interface software for the Magnum

universal flowmeter. Currently Magio 3.0 is modeled to provide the user access

to the site specific setup of the Magnum flowmeter and some test functions. In



the future, as further hardware expansions are added to the basic instrument, the

software may be expanded to control additional functions.

R equirements: IBM PC based Computer

486 or higher CPU (Pentium 100 or above recommended)

16 Mb of RAM (32 Mb or more recommended)25 Mb of free disk space

800 x 600 display resolution at 256 colors

Free serial port (communication with flowmeter)

Port Selection

Magio 3.0 requires a free serial port on your PC/laptop. Laptop computers today

usually have Com 1 available because they are equipped with a touch-pad or a

PS/2 mouse. Desktop systems also have Com 1 available if a PS/2 mouse is

being used. Com 2 is usually reserved for the modem. Unfortunately computers

differ greatly in their configuration and neither port may be available. In this case

it may be necessary to temporarily unplug the mouse from your computer and

start up Win 95/98 without a mouse. Magio 3.0, like the Windows operating

system itself can be operated by Alt-F, Tab, arrow and Enter keys alone. It may

take a little practise, but it is quite possible as a last resort.

Magio 3.0 Login

When you run Magio 3.0 you will be presented

with the above login window. There are 3

levels of access. As standard user no login is

required and you can proceed by clicking

"OK". The second level allows access to

additional features such as data-logging, if the

hardware is present in the Magnum you have purchased (see also under Data-

logging). A login ID and password will be provided at that time.

Datalogging

If your Magnum is equipped with datalogging you will receive a password that

will enable an additional tab in the MAGIO 3.0 software. Currently the capacity

of the chip is about 20,000 recordings (about 14 days at 1 minute log frequency).

http://www.magmeter.com/manual/ports.html











The data remains stored even when the power is turned off. The interface below

permitts the setting of date and time at which the log starts and the download of

the stored data to a text file that can then be further processed by programs such

as MS Excell or others.

1) Starting date: The date at which your recording will start in this format(DD:MM:YY)

Y2K note: Although the program displays only the last two digits of the

year, it actually stores all four digits and is fully

Y2K compliant.

2) Starting time: Time at which your recording will start (H:MM:SS)

Note: The datalogger should be initialized at the measurement location. You

should be aware that if

the datalogger is setup elsewhere and then later restarted at the measurement

location the time index will be off.

3) Log frequency: 0-999 minutes interval between recordings. 0 = datalogger

disabled

4) Transmit: Send datalogger settings to flowmeter.

Note: Whenever any settings are changed (flowmeter or datalogger) the

instrument assumes it is being set up for a new

application. In each case you will be prompted to download all recent data

and clear the datalogger. New settings

cannot be transmitted until the logger has been cleared.



The remaining functions are quite self explanatory. The download file will have

the extension *.msr, but will be a simple text file which also includes setup

information about the flowmeter with wich the recording was made. Depending

in the amount of stored data some operations including the download itself may

take a few minutes. You will have options to change the name of the file and

where it will be stored.

Your data download will look something like this:



The "Live Feed" screen is the default start-up screen of the Magio 3.0. It is only

active when a connection with a Magnum flowmeter has been established. If the

software is being used for training and demonstration purposes, or for pre-

recording flowmeter settings the following is what you will see. If a Magnum isattached to a serial port of your computer click on the "Connect" menu and click

on "Open Channel". You may see a message stating that the configured serial

port is invalid. This can be caused if the Magio software is unable to recognize

the ports on your PC, but is usually no cause for concern. Simply click "OK" and

the default Com. (usually com. 1) will be selected regardless (see more important



info on port selection HERE). The software will automatically download all

existing settings from the flowmeter and the display will become syncronized.

Once the flowmeter has been configured for volume an additional totalizer

window will become visible left of the velocity window; as well as an "eraser"

button, allowing clearing of the totalizer.

The units displayed on this screen depend on the settings the Magnum has once it

is connected to Magio 3.0 or which ever you subsequently decide on using. The

above is the original default screen.

In order to change any of the settings with which the flowmeter was shipped, or

to change existing settings a previous user chose originally, click on the "Flow







Config. I" tab and you will get the following screen. Proceed to choose the

desired settings by clicking on pull-down menus and entering numbers. This

should be fairly self-explanatory. The software will automatically calculate and

display the insertion dimension and present the user with a proposed range for

the meter, based on an average flow velocity of 2 m/s (~6ft/s). This represents

most common applications, but can be overridden by the user to chose a specificrange. If you require further information click and hold any of the "help" buttons.

Once you are done click "Continue".







Flow Config. II deals with the output signals supplied by the Magnum

flowmeter. The user has a choice between standard 4-20mA or 0-20mA analog

output. 20mA will automatically correspond to 100% of your chosen range and 4

(0) to zero flow. Magnum can also supply this output for reverse, i.e. "Two Way"

flow, in which case the output must be switched between two external gauges

using the alarm as the switchover relay. The wiring diagram to the lower right ofthe window shows exactly how this needs to be set up. When there is no

flowmeter connected the "Test Devices" buttons will be inactive. If a Magnum is

attached you can test the 4-20mA and pulse outputs. You can also determine the

exact length of pulse Magnum supplies based on the requirements of your

externel hardware. The alarm setting allows you to program one of the pulse

outputs to act as an alarm switch if the flow hits a certain minimum or maximum

flow. When done hit "Continue" to move to the next tab.



The "Signal Dampening" tab deals with the way in which the flowmeter reading

responds to changes in flow. Unfiltered fully developed turbulent flow, as it

exists in most pipes over 3", would produce a seemingly erratic flow reading. In

order to produce a reasonably stable flow reading it is desirable to introduce

some signal filtering. Magio 3.0 offers 7 settings from "none" to "High". The

way in which the flowmeter will react is illustrated by the red line graph below.The higher the filter, the longer it will take Magnum to react to a change in flow

and settle at the new level of flow. It is important to keep in mind that a high

setting will make the flowmeter react very slowly, and in applications where

flows change frequently this may not be a desirable setting. Generally a setting

somewhere in the middle will suit most applications.



If the application is particularly turbulent or noisy it is possible to add another

kind of filter called the "window". Once a steady reading has been established it

dampens the signal for a few percent above and below this reading in order to

achieve as straight a line as possible. If the flow changes above or below this

"window" the flowmeter reacts faster again. It is important to keep this window

as small as possible in order to eliminate undesirable noise, but to keep the meter

able to react to real changes in flow.

Zero Suppression allows the user to force the reading to zero if it falls below a

certain percentage of flow.

When done hit "Continue".



The final tab recaps all settings the user has just chosen for the flowmeter. Once

familiar with the operation of the flowmeter any advanced user can proceed right

to this screen and input data here. When done hit "Accept Settings" to

communicate the new information to the flowmeter. Unless this button is hitnone of the input or changes just made will be communicated to the flowmeter.

After a few seconds the flowmeter will reply with a small window: "Settings

Accepted".

This is also a convenient place to pre-record settings for a specific instrument or

to load an implement settings recorded earlier. For the former, input the desired

settings and under the "File" menu chose "Save Settings". A window will appear

which will allow the user to save a particular setting in under any name and in

any desired directory as a *.MSR file. To load pre-recorded settings choose

"Load Settings" from the "File" menu and find the desired file with a *.MSRlabel. Hit "Apply Settings" to communicate the new data with the Magnum.

If you have a Magnum equipped with datalogger the "Apply Settings" button will

bring up a window that gives you a chance to download the information currently

stored on the datalogger. Once new settings are applied the datalogger will be

cleared. This is meant to insure that the records kept by the logger are consistent

for one specific application.

The "Default Settings" will return both software and flowmeter (if connected) to

the factory settings with which they were shipped.

The "Revert Back" button will revert to the settings last stored in the Magnum

flowmeter.



Datalogging

If your Magnum is equipped with datalogging you will receive a password that

will enable an additional tab in the MAGIO 3.0 software. Currently the capacity

of the chip is about 20,000 recordings (about 14 days at 1 minute log frequency).

The data remains stored even when the power is turned off. The interface below permitts the setting of date and time at which the log starts and the download of

the stored data to a text file that can then be further processed by programs such

Maintenance

Ordinarily the Magnum flowmeter should be ready to operate right out of the box

and should not require any maintenance or service. The Magnum has no

measurement drift and consequently no re-calibration should ever be required.

Still there is a few matters of common sense that you may take into amount:

1) If the flowmeter is intended to be moved frequently it may be a good idea to

grease the thread of the Universal mounting mechanism. If it is intended to stay

in place this may not be necessary.



2) If the liquid being measured contains matter that could collect on the sensor or

electrodes (fiber, grease or mineral build-up) it may be advisable to remove and

clean the sensor periodically as part of your regular maintenance procedures.

This very much depends on your specific application and we can give no

recommendation as to how often this should be done. Here is a demonstration of

how to dis-assemble Magnum.

3) If something is not working as you believe it is supposed to contact the

manufacturer first and if the problem cannot be solved over the phone arrange to

return the instrument to our factory for a free check-up (freight not included). Do

not attempt to modify or repair any part of the instrument yourself or the

warranty will become void.

Troubleshooting

Symptom:

The reading seems erratic

Possible Cause: Remedy:

Incorrect grounding of the flowmeter can

affect reading

Flowmeter should only be grounded to liquid

(see also here) Air is interrupting the measurement ensure the sensor is fully submerged

Air is trapped on top of pipe install the sensor at an angle

Air is being pulled in through vortex move sensor to different location

Sensor or cable may be damaged return for repair

measurement accurately reflects reality none

pipe is empty none (turn off flowmeter)

sensor cable has been detached re-attach cable (turn power off first !)




http://www.magmeter.com/ground.htm







The meter reads low or high compared to another source of information (other

instrument, pump curve, etc.)

The comparison meter is When comparing two instruments make sure they are both



not set to the same range using the same measurement range (scale).

The other instrument is not

properly calibrated

The tendency is to believe the old measurement rather then the

new. If all is set up correctly you should assume that the

Magnum gives you correct information.

Pumps do not always

deliver the specifiedcapacity

Magnum is correct

Doubling the number of pumps does not double the

flow

Magnum is correct

The pipe is not completelyfilled

Magnum is showing more flow then really present because itassumes a filled pipe. Move the meter to a different location.

The meter shows zero when there is flow

Sensor orientation is off point arrow on top end of sensor in flow dirction.

Sensor, cable, or transmitter damaged return for repair

The display stays blank or shows only partial caracters

Display has been damaged return for repair

4-20mA output seems incorrect

Using external power source to drive 4-

20mA circuit

Magnum has a self powered 4-20mA output.

Do not use an

Magnum is slow to react to flow

Filter and/or window has been set too high Reduce filter and/or window size

DO NOT:

- attach the sensor cable to the transmitter while it is powered up. - cut or modify the sensor cable. It is part of the calibration.

- submerge the transmitter.

- expose the connector end of the sensor cable to moisture.

- remove the snap-ring from the universal mounting mechanism unless thetap valve is securely closed.

- expose the cable or sensor to temperatures above 100 C unless they are

part of the High Temperture model.

Magnum is supplied with a power pack (110VAC - 12VDC Plug-in class 2 transformer. UL and CSA listed,81J1 E81356). The electrical supply to the transmitter should NOT be grounded under any circumstances.

Ideally the only ground the probe should be connected to is the grounding through contact of the sensor body

with the liquid.

Since there are potential differences between the different grounds provided by earth, electrical and pipe

ground, that could interfere with Magnum, all other grounding of the probe and transmitter should be

avoided.
