As an indispensable instrument in industrial control process, flowmeter plays a vital role in production. Electromagnetic flowmeter is a classic flowmeter. Its schematic diagram is as follows:

[Schematic diagram of electromagnetic flowmeter]

The composition of electromagnetic flowmeter mainly includes measuring tube, sensor, circuit board and display panel. Among them, the measuring tube is the main component of the electromagnetic flowmeter, the sensor is responsible for converting the flow signal into an electrical signal, and the circuit board processes and converts the electrical signal, and finally displays the flow value on the display panel.

In terms of working principle, electromagnetic flowmeter uses Faraday's law of electromagnetic induction and the principle of magnetic field interaction. When the conductive liquid passes through the measuring tube, the charge in the fluid will be affected by the force of the magnetic field in the conductive liquid, thereby generating an induced potential of the liquid. The sensor converts the potential signal into an electrical signal, which is then processed and converted by the circuit board, and finally displays the flow value.

electromagnetic flowmeter has the advantages of high precision, good stability and high reliability, so it is widely used in chemical industry, petroleum, metallurgy, water conservancy, municipal and other fields, and has become an important part of production automation control. And the in-depth understanding of the schematic diagram, more help us in the use and maintenance of electromagnetic flow meter more handy.

Nowadays, with the continuous progress of science and technology and the expansion of the scope of application, electromagnetic flowmeter has also been further improved and developed. With the development trend of digitalization and intelligence, it is constantly applied to new fields and has a very high development prospect. Therefore, mastering the basic principle of electromagnetic flowmeter is particularly important for industrial control personnel.
