The principle of electromagnetic measurement is based on Faraday's law of electromagnetic induction, in which an electromotive force is generated in proportion to the flow velocity when a conductive fluid crosses a magnetic field. Our electromagnetic flowmeter has no pressure drop and can measure a wide variety of liquids. Various lining materials (PFA, PTFE, ceramics, polyurethane rubber, natural soft rubber, natural hard rubber) and our unique dual frequency excitation method ensure stable flow measurement even with corrosive or slurry fluids. The bore size ranges from 2.5 mm to 1800 mm. The capacitive electromagnetic flowmeter is suitable for measuring low conductivity and high concentration slurry fluids.
