2. Working principle of HGD electromagnetic flowmeter
The working principle of HGD electromagnetic flowmeter is to use the principle of electromagnetic induction for measurement. When the liquid passes through the measuring tube of the electromagnetic flowmeter, an electromotive force will be generated in the liquid. The magnitude of the electromotive force is proportional to the flow rate of the liquid. The flow rate of the liquid can be determined by measuring the magnitude of the electromotive force. Specifically, the HGD electromagnetic flowmeter is composed of electrodes, electromagnetic field generators, inductance coils, signal processors, etc. The electromagnetic field generator generates a magnetic field, and the electrodes induce an electromotive force under the action of the magnetic field. The inductance coil converts the electromotive force into an electrical signal, and the signal processor processes and outputs the signal.
