The split type electromagnetic flowmeter is designed based on Faraday's electromagnetic induction principle, which is used to directly measure the instantaneous flow of conductive liquid in the closed pipeline, and has the flow accumulation function. In the field monitoring display at the same time, can output standard current signal, pulse signal and RS485 digital signal, for recording, adjustment, control use, to achieve automatic control of detection. It can be widely used in tap water, chemical industry, coal, environmental protection, textile, metallurgy, paper and other industries.
