What are the problems encountered when electromagnetic flowmeters are used in paper mills

Electromagnetic flow meters operate based on a fundamental principle of electromagnetic induction, providing an accurate and reliable method for measuring the flow of conductive fluids. The working principle involves Faraday’s law of electromagnetic induction.

According to Faraday’s law, an electromotive force (EMF) is induced in the fluid perpendicular to both the magnetic field and the flow direction. The induced EMF is directly proportional to the flow velocity of the fluid.

The electromagnetic flowmeter is constructed in such a way that it mainly consists of a number of key components that work together to measure the flow of a conductive liquid. The following is the main structure of the electromagnetic flowmeter and its functions:
