Plug-in electromagnetic flowmeter is a kind of flowmeter applying Faraday's law of electromagnetic induction. The flowmeter is innovative on the basis of electromagnetic flowmeter, and the sensor is innovatively designed according to the principle of Top Transform. The traditional double-electrode structure is transformed into a single-electrode structure, and the other electrode is treated as a virtual electrode. The sensor structure adopts a single electrode, and the coil is placed on both sides of the electrode to control the distribution trend of the magnetic force line, so as to achieve high stability, reliability and precision measurement, and expand the sealing space of the sensor.
Features of plug-in electromagnetic flowmeter products:
_Programmable low frequency rectangular wave excitation improves the stability of flow measurement and reduces power loss.
