Electromagnetic Flow Meter
Magnetic flow meters work based on Faraday’s Law of Electromagnetic Induction. According to this principle, when а conductive medium passes through a magnetic field B, a voltage E is generated which is proportional to the velocity v of the medium, the density of the magnetic field, and the length of the conductor. In a magnetic flow meter, a current is applied to wire coils mounted within or outside the meter body to generate magnetic field. The liquid flowing through the pipe acts as the conductor and this induces a voltage that is proportional to the average flow velocity. This voltage is detected by sensing electrodes mounted in the Magflow meter body and sent to transmitter which calculates the volumetric flow rate based on the pipe dimensions.
