MGG/KL remote electromagnetic flow meter

remote electromagnetic flow meterDescription of remote electromagnetic flow meter

Electromagnetic flow meter depends on Fraday’s law of electromagnetic induction. It is used for measuring thevolume flow of conductive liquid in the pipe. Not only general process measurement, but alsothe total measurement and trade settlement.
It is widely used in petroleum, chemical industry,steel, food, electricity, papermaking, water conservancy, water supply&drainage, water resource, management and etc.

Selection of Installation Position

(a) The fluid direction and direction on the sensor should keep same.

(b) Ensure the fluid is full in the pipe.

(c) Choose small pulse flow location far away from pump and local resistance parts(valves and


(d) Choose the position that not easy to cause the phase separation when measure the two-

phase fluids.

(e) Avoid the the position with negative pressure in the pipe.

Requirements Of Upstream Straight Pipe

Please refer to following table about the requirements to upstream straight pipe. There is no

requirements for downstream straight pipe, which will not influence the measuring accuracy. If

the diameter of upstream and downstream straight pipes is different with the nominal diameter

of sensor, it should install diffusion tube or reducing tube, and the cone angle should be less than

15 degree(best is 7-8 degree), then connect with pipe.

Note: L is the multiple of nominal diameter of sensor,

D is nominal diameter of sensor.
