What Is Plug-in Electromagnetic Flowmeter?

The working principle of Plug-in Electromagnetic Flowmeter is based on Faraday's law of electromagnetic induction.

In the electromagnetic flowmeter, the conductive medium in the measuring tube is equivalent to the conductive metal rod in the Faraday test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field.

When a conductive medium flows, an induced voltage is generated. The two electrodes inside the pipe measure the induced voltage generated. The measuring tube is electromagnetically isolated from the fluid and the measuring electrode by a non-conductive inner liner (rubber, Teflon, etc.).

At the same time, we have Digital Water Meter and Oil Flow Meter to export all around the world. Welcome to contact us.
