Electromagnetic Flowmeters – SEMF Series

Highly Precise and Reliable

An electromagnetic flowmeter (Mag meter) works based on Faraday’s Law of Electromagnetic Induction. When a conductive fluid flows through a magnetic field, a voltage is induced that is proportional to the flow velocity. Since the pipe diameter is fixed, this velocity directly provides the volumetric flow rate. Unaffected by fluid viscosity, density, pressure, or temperature, it provides highly precise measurements for conductive liquids, wastewater, and corrosive chemicals.
