How do electromagnetic flowmeters measure the flow of water?

Electromagnetic flowmeters operate based on Faraday's law of electromagnetic induction, which states that a voltage is induced when a conductive liquid flows through a magnetic field. In the case of water flow measurement, the flowmeter generates a magnetic field across the flow tube. As the water, which is a conductive fluid, moves through this magnetic field, it generates a voltage proportional to the velocity of the flow. This voltage is then measured and processed to provide an accurate flow rate.

This method is particularly effective for measuring various conductive fluids, including wastewater and treated water, making it a reliable choice for environmental compliance and other applications where precise flow measurement is necessary.
