An electromagnetic flowmeter is a device used to measure the flow of electrically conducting liquids. Electromagnetic flowmeters are widely used in the water supply and sewage industry to measure water and wastewater flow. They are also used in measuring the flow of technological water (e.g. in mines) or in the food industry (e.g. juice production, dairies). The device works on the principle of Faraday's law of electromagnetic induction and uses the phenomenon of electromagnetic induction.
