- Measuring principle
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 flowmeters 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:
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 |

- Application
Electromagnetic flowmeters have been used throughout industries for more than 60 years. These meters are applicable for all conductive liquids, such as: Domestic water, industrial water, raw water, ground water, urban sewage, industrial wastewater, the processed neutral pulp, pulp slurry, etc.
