MICRO Electromagnetic Flow Meter, simply known as mag flow meter is a volumetric flow meter which is ideally used for any conductive liquid and other applications that experiences low pressure drop and with appropriate liquid conductivity required.
This flow meter works on Faraday's Law of electromagnetic induction. In a magnetic flow meter, a current is applied to wire coils mounted within or outside the meter body to generate a magnetic field. The liquid flowing through the pipe acts as a conductor and this induces a voltage which is proportional to the average flow velocity. This voltage is detected by sening electrode mounted in the mag flow meter body and sent to a transmitter which calculates the volumetric flow rate based on the pipe dimensions
