SUP-LDG Carbon steel body electromagnetic flow meter

Magnetic flowmeters operate under the principle of Faraday's Law of Electromagnetic Induction to measure liquid velocity. Following Faraday's Law, magnetic flowmeters measure the velocity of conductive liquids in pipes, such as water, acids, caustic, and slurries. In order of usage, magnetic flowmeter use in water/wastewater industry, chemical, food and beverage, power, pulp and paper, metals and mining, and pharmaceutical application.

  • 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-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
