Magnetic flowmeters (magnetic meters or mag meters) monitor and measure the flow of chemically compatible conductive liquids (such as water) in water treatment, irrigation, and food processing applications. Flowing liquid passes through a magnetic field created by the meter's electromagnetic coils, generating a voltage proportional to the fluid's velocity. The meter uses fluid velocity to calculate and display a flow rate measurement. Magnetic flowmeters have no moving parts. As a result, they don't impact line pressure or impede flow rates, providing highly accurate flow rate readings.
