Background
Since the principle of electromagnetic flow meters is based on faraday's law of electromagnetic induction. Electromagnetic flow meters generally consist of a measuring tube with a non-conductive inner surface, coils connected in series and arranged radially along the pipe, and at least two electrodes. When the conductor cuts magnetic lines of force in the magnetic field generated by the coil, an induced potential is generated in the conductor, the magnitude of the induced potential is in direct proportion to the effective length of the conductor in the magnetic field and the speed of the conductor moving in the magnetic field in the direction perpendicular to the direction of the magnetic field, and the current induced potential is measured through the measuring electrode. The traditional electromagnetic flowmeter is influenced by the change of a magnetic field caused by the displacement of a coil after being subjected to external interference, so that the accuracy and the stability of the flowmeter are influenced, a measured value is inaccurate and unstable, and the measurement is influenced.
