Working Principle of Electromagnetic Flowmeter
The working principle is based on Faraday's Law of Electromagnetic Induction, that is, when the conductive liquid
flows through the electromagnetic flow meter, the induced electromotive force will be produced in the conductor,
and the induced electromotive force is directly proportional to the velocity of conductive liquid magnetic flux
density and width of conductor (inside diameter of flow meter).
Such induced electromotive force is detected by a pair of electrodes on the tube wall of the flow meter, and the
rate of flow can be acquired by mathematical operation. The equation of induced electromotive force is as flollows:
E: induced electromotive force.
D: inside diameter of measuring pipe
B: magnetic flux density.
The following conditions should be satisfied in order to abtain sabsfactary measuring accuracy:
For example: 100-1 03-1, 6E00-0010
Note: Intelllgent electromagnetic flowmeter DN100 has a fixed stalnless steel electrode and chloroprene rubber lining. with a rated pressure of
1 .6 Mpa a temperature less than or equal to 60 degrees centigrade and protection gread of IP65 . It is of integral type. Case material and fange
are made from carbon steel . with mounting companion flanges (including bolt and nut). It ìs powered by 220V AC power supply.
