Top 10 Manufacturer Agriculture Modbus Water Electromagnetic Flow Meter

The working principle of Sanitary Flow Meter is based on Faraday's law of electromagnetic induction. In the electromagnetic flowmeter, the conductive medium in the measuring tube corresponds 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, it will produce the induced voltage (working principle as shown below). The two electrodes inside the pipe measure the induced voltage generated. The measuring pipe is electrically isolated from the fluid and the measuring electrode by non-conductive linings (rubber, Teflon, etc.). The function of the electromagnetic flowmeter on the market is quite different, simply measuring the one-way flow, only outputting the analog signal to drive the post instrument; the multi-function instrument has measured the bidirectional flow, the range switch, the upper and lower limit flow alarm, the empty tube and the power cut off Alarm, small signal removal, flow display and total calculation, automatic check and fault self-diagnosis, communication with the host computer and motion configuration.
