working principle:

Electromagnetic flowmeter is an inductive instrument that measures the volume flow of conductive medium in the pipe according to Faraday's electromagnetic induction law. It adopts the embedded technology of single chip computer to realize digital excitation. At the same time, the electromagnetic flowmeter adopts CAN field bus. In addition to measuring the flow of general conductive liquid, it can also measure the volume flow of liquid-solid two-phase flow, high-viscosity liquid flow and salt, strong acid and strong alkali liquid. It is widely used in chemical industry, environmental protection, metallurgy, medicine, paper making, water supply and drainage and other industries.

Product features:

High definition backlight LCD display, full Chinese menu operation, easy to use, easy to operate, easy to learn and understand.
