Working Principle

Based on Faraday’s Law of Electromagnetic Induction, the Electromagnetic Flowmeter’s operation produces an induced electromotive force in the liquid conductor as the conductive liquid flows through it.

This electromotive force is directly proportional to the liquid’s velocity, the magnetic flux density, and the conductor’s width (interior diameter of the flowmeter). A pair of electrodes on the flowmeter’s tube wall detect this generated electromotive force, which has the following equation for its magnitude:

U = K×B×V×D

U: Induced electromotive force

K: Instrument Constant

B: Magnetic flux density

V: Velocity

D: Interior diameter of measuring pipe
