An electromagnetic flow meter (also known as a mag meter) is a type of flow meter used to measure the flow rate of electrically conductive fluids such as water, sewage, and slurries. It operates on the principle of Faraday’s Law of Electromagnetic Induction, which states that a voltage will be induced in a conductor moving through a magnetic field Electromagnetic flow meters are commonly used in Water and wastewater treatment, Chemical Processing, Food and beverage production, Mining and mineral processing, Agriculture and irrigation
