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