Mag meter works based on Faraday`s law, and measure conductive medium with conductivity more than 5 μs/cm and flow range from 0.2 to 15 m/s. An Electromagnetic Flowmeter is a volumetric Flowmeter that measures the flow velocity of a liquid through a pipe.
The measurement principle of magnetic flow meters can be described as follows: 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:
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
