Electromagnetic Flow Meters

SMART MEASUREMENT – Electromagnetic Flow Meters

Electromagnetic flowmeters, also known as magnetic flow meters, mag meters, or magflow meters, offer a number of practical advantages over traditional flow metering technologies which employ mechanical measuring techniques.

The simple construction of our electromagnetic flow meters is the key to these advantages. A SmartMeasurement magnetic flow meter does not contain any moving parts, rotating gears or turbines, or bearings. Instead, it relies on two electrodes to measure the density of the induced magnetic field that results from an electrically conductive fluid, such as water, flowing through a pipe. The density of the magnetic field is directly proportional to the fluid velocity of the flowing liquid.
