FMI100 electromagnetic flowmeter is designed based on Faraday's law of electromagnetic induction: When the conductive liquid cuts the magnetic force in the magnetic field, the conductive potential is generated in the conductor. When the flow rate is measured, the conductive liquid flows through the magnetic field perpendicular to the flow direction at the speed of V. The conductive liquid flow induces a voltage that is proportional to the average flow rate. And through the cable to the converter through intelligent processing, to achieve the instantaneous fluid flow, accumulated flow display and flow data and communication between the control system.
