Electromagnetic Flow Meter

FMG900-Series Electromagnetic Flow Meter

The complete lack of moving parts of this insertion Electromagnetic Flow Meter is the source of its reliability. There is no rotor to stop turning in dirty water and there are no bearings to wear out. Brass and stainless steel models withstand a variety of temperature, pressure, and chemical conditions. Reverse flow output and immersibility are optional. A rapidly reversing magnetic field is produced in the lower housing. As the fluid moves through this field, a voltage is generated that is measured and translated into a frequency signal proportional to flow rate.
