The electromagnetic flowmeter is a kind of inductional instrument designed by Faraday’s law of electromagnetic induction to measure the flow of conductive media in the tube. It adopts the technology of insertion of a single chip to realise digital excitation and employs a CAN local fieldbus. It was first invented in China and its technology amounts to the leading level at home. The electromagnetic flow meter can realize local indication and output electrical current at a single of 4-20mA which can be used to record, adjust and control. Now electromagnetic flow meters are widely used in industrial sectors such as chemical industry, environmental protection, metallurgy, pharmaceutical, paper making, water supply and removal etc.
Besides measuring the flow of general conductive liquid the electromatic flowmeter can measure the flow of liquid-solid mixed fluid, high-viscosity fluid and salt, strong acid and strong alkali.
