Electromagnetic flow meters are devices used to measure the flow rate of conductive liquids. They operate based on the principle of electromagnetic induction, where a magnetic field is applied to the liquid, generating a voltage proportional to the flow velocity. This voltage is then converted into a flow rate reading. These flow meters are commonly used in various industries, including water treatment and chemical processing. They are particularly effective for measuring fluids with low viscosity and can handle a wide range of temperatures and pressures. Their non-intrusive design ensures minimal maintenance and long-term reliability.
