Measuring principle

Mag meter works based on Faraday's law, when the liquid goes through the pipe at the flow rate of v with a diameter D, within which a magnetic flux density of B is created by an exciting coil, the following electromotive E is generated in proportion to flow speed v:

E=K×B×V×D

Where:
E－Induced electromotive force
K－Meter constant
B－Magnetic induction density
V－Average flow speed in cross-section of measuring tube
D－Inner diameter of measuring tube
