An electromagnetic flowmeter (also known as an “EMF”) is a type of flowmeter that measures the flow of conducting liquids and slurries by utilizing the principles of Faraday’s law of induction. The water flow meter determines the flow rate by utilizing a magnetic field to generate a voltage difference across a conductor moving with the fluid, which is directly proportional to the flow... https://www.jxdqjc.com/1489.html
