The intelligent integrated electromagnetic flowmeter is an induction instrument that measures the volume flow rate of conductive medium inside a tube based on Faraday’s law of electromagnetic induction. It uses embedded technology with a microcontroller to achieve digital excitation. Electromagnetic flow meters can not only meet on-site display requirements, but also output 4-20mA current signals for recording, regulation, and control. They have been widely used in industrial technology and management departments such as chemical, environmental protection, metallurgy, medicine, papermaking, and water supply and drainage.

Measurement principle of integrated intelligent electromagnetic flowmeter:
The measurement principle is based on Faraday’s law of electromagnetic induction. That is, when a conductive liquid cuts magnetic field lines in a magnetic field, an induced electromotive force is generated in the conductor, and e is the magnetic field perpendicular to the flow direction through which the fluid flows when measuring the flow rate. The flow of conductive liquid induces a voltage signal proportional to the average flow velocity (i.e. volume flow rate). The induced voltage signal is detected through two electrodes in direct contact with the liquid and transmitted to the amplifier through a cable, which is then converted into a unified current output signal.
