Electromagnetic Flow Meters
Electromagnetic flowmeters, also known as magnetic flow meters or simply mag 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.

High Precision Mag Meter Technology
Specific advantages that our magnetic flow meter technology provides include:
- High accuracy
- Low cost
- Little to no pressure loss
- Readings that are unaffected by changes in density or viscosity
- No susceptibility to bearing wear or other mechanical wear-and-tear issues
Because the only wetted components in a SmartMeasurement electromagnetic flow meter are the electrodes and the liner, these components can be fabricated from a variety of materials to make the mag meter compatible with virtually any electrically conductive fluid, including aggressive acids.
The only real limitation of the electromagnetic flow meter is that the measured fluid media must be electrically conductive (> 5μS/cm). Non-conductive fluids, such as oil and other petroleum-based fluids, cannot be measured with mag meter technology.
