Electromagnetic Flowmeter for a Wide Range of Fluids

The working principle of the electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The details are as follows:Basis of the law: When a conductor cuts magnetic flux lines in a magnetic field, an induced electromotive force is generated, and its magnitude is proportional to the conductor's movement speed, magnetic field strength, and the effective length of the conductor in the magnetic field. Flow induction: In an electromagnetic flowmeter, the measured conductive liquid is equivalent to the conductor in Faraday's law of electromagnetic induction. The sensor part of the flowmeter consists of a pair of magnetic poles and a pair of electrodes. The magnetic poles generate a magnetic field, and the electrodes are used to detect the induced electromotive force. When the conductive liquid flows in the measuring tube, it is equivalent to the conductor cutting the magnetic flux lines in the magnetic field, thereby generating an induced electromotive force in the liqu…
