GENERAL INFORMATION

This manual will assist you in installing, using and maintaining Electromagnetic Flow meter. It is your responsibility to make sure that all operators have access to adequate instructions about safe operating and maintenance procedure.
Warning
For your safety. review the major warnings and cautions below before operating your equipment.

Use only fluids that are compatible with the housing material and wetted components of your Electromagnetic Flow Meter.

When handling hazardous liquids. always exercise appropriate safety precautions.
When measuring flammable liquids, observe precautions against fire or explosion.

When working in hazardous environments. always exercise appropriate safety precautions
Handle the sensor carefully. Even small scratches or nicks can affect accuracy.

For best results, calibrate the meter at least 1 time per year.
Do not purge the flow meter with compressed air.

During Electromagnetic Flow Meter removal, liquid may spill.Follow the manufacturer’s safety precautions for clean up of minor spills

1.2 Unpacking and inspection
Upon receipt. examine your meter for visible damage. The meter is a precision measuring instrument and handled carefully. Remove the protective plugs and caps for a thorough inspection. If any items are damaged or missing. contact us.
Make sure the flow meter model meets your specific needs. For your future reference, it might be useful to record this information on nameplate in the manual in case it becomes unreadable on the meter.
Transportation and Handling
Do not lift the detector from the Converter housing. the junction box or the connecting cable. Use lifting lugs for larger sizes is recommended. Very large meter sizes are packed and crated with the meter laying on its side for shipping safety and stability reasons. In order to lift the meter in vertical position. its recommended to use a sling rigged method as shown below. Warning: NEVER introduce the forklift, chains, wire slings or any other sharp object inside the flow tube for lifting or handling purpose. This could permanently damage the isolating liner and could render the meter inoperable. If using a forklift, do not lift the detector from its body between the flanges. The housing could be accidentally dented and permanent damage could be caused to the internal coil assemblies.

3.2 Installation consideration

The pipe is cleared before installation.We recommend to install magnet filter up the instrument.
You should take out stuffing for fixing pointer.

The central line of instrument must be straight line with pipe line.The angle between pipe line and central line of instrument is not exceading 20.
The instrument diameter is the same with pipe diameter and straight pipe H instrument & L instrument should be 5 times meter’s diameter and 250mm.

There are not any stealmagnet materials around the meter.
We recommend install a valve at output flow for gas measurement.

When there is stress. you should add supporter at front and behind instrument.
When installing instrument lining PTFE, the press force should not overlight.

LCD display should avoid straight light.
When low temperature.need steam jacket.

FAILURE ANALYSIS AND SOLUTION

8.1 Vibration
8.1.1 Gentle vibration: caused by media fluctuation. can be prevented by damping.
8.1.2 Middle vibration: caused by media flow status, regarding to the gas, normally caused by the unstable operation pressure, which can be prevented by stable pressure or flow control device, or increase the meter damping.
8.1.3 Strong vibration: caused by media pulsation, unstable air pressure, or the client supplied gas operation pressure, temperature, and flow cannot comply with real situation on the meter, which is over the measuring scope under big differential.
8.2 Pointer stop at some position without movement
Main reason is the float blocked. During the normal operation. the valve open too fast. which caused the float quickly move up and strike the movement controller, and the movement controller will be out of shape and then block the float. The float oriented lever may also be not concentric with the movement control ring. and block the float. To solve this. first shall take apart the meter, and take away the movement controller to make the shape back to original, then check the if it is concentric with the oriental lever, assembly the float and to make it move up and down. smoothly, meanwhile the meter shall be assembly vertically or horizontally, otherwise meter will be blocked and has measurement error.
8.3 Large measuring error
8.3.1 Assembly procedure cannot comply with the requirement
A: Regarding the vertical installed meter. it shall be vertical assembly and the incline shall not be more than 2.
B: Regarding the horizontal installed meter, it shall be horizontally assembly and the incline angel shall not be more than 2.
C: No magnetic subject is allowed within area of 100mm from the meter.
D: The assembly position shall be away from the valve diameter changing port. pump outlet. non- direct pipe line port, to meet the requirement of 5d ahead and 250mm behind of the direct pipe line.
8.3.2 Big media density change is also on reason of the bigger measurement error. Before calibration, all the media density will be converted according to client supplied media density, it will be calibrated based on water flow under standard status, if the media density has big media density in the formula. convert to the error revised factor, then the real flow rate will be the measured flow rate times with the factor.
8.3.3 Gas media will be effected by the temperature and pressure. suggest to use the pressure and temperature compensation method to get the real flow rate.
8.3.4 With long time usage and pipe vibration, the meter sensor magnetic steel. pointer. weight. and rotating magnetic steel parts will be less crowded, which will make bigger measure-ment error. The solution: to test it by move the pointer manually. to make the pointer in the position of RP. check it the output is 4mA and flow rate is 0%. and then test by the degree. if not comply with the requirement, then to calibrate the parts on the position. It is requirement that the professional technician to make the calibration. otherwise it will make the position lose and shall be back to the manufacture for calibration.
8.4 No current output
8.4.1 Check if the wire connection is correct.
8.4.2 No liquid crystal display, if there are display but no output. may the output tube damaged the circuit board need to be replaced.
8.4.3 Lose the calibration value.The meter calibration value lose due to the E2PROM failure, it can caused no current output. but the current value is not changed. Solution to recover the operation by data recovery. if not succeed, first set the data of code 2000. then set the data of code 2008. the method is calibrating the data from RP- 100% by push the pointer manually.
8.5 No site display
8.5.1 Check if the wire connection is correct.
8.5.2 Check if the power supply is correct.
8.5.3 Reinstall the liquid crystal module, and check if the connection point is solid.
8.6 The site liquid is 0 of full scope
8.6.1 Set the scope and zero data by checking the 2000 code. it is required that the ZERO value is lower than Span value, the two values are not equal.
8.6.2 Check the sample data, push the pointer manually to check the change of the sample value, if there are no changes, then it will be sample circuit failure, it is necessary to replace with the circuit board.
8.7 No correct alarm
8.7.1 Check the error set value D cannot be too higher.
8.7.2 In the function of FUN, check if the logic function is correct. HA-A means up limit of positive logic. LA-A means low limit of positive logic.
8.7.3 Check alarm set value of SU.
8.7.4 Check if the liquid crystal tap display is correct, there are output but no movement, check the outside power supply and if the negative pole of the outside power supply is correct connected.
8.7.5 Circuit board failure. replace with new.
8.8 Accumulated pulse output is not correct
8.8.1 Check the alarm of the accumulated pulse output is set on ZERO.
8.8.2 Circuit board failure. replace with new.
