The FMG-550 Series magmeter flow sensors are heavy-duty, high-performance sensors in an adjustable, insertion configuration that can be used with a ball valve for hot-tap installations. This insertion-style flow sensor has no moving parts and is constructed of corrosion-resistant materials to provide long-term reliability with minimal maintenance costs.

The FMG-550 Series is versatile and simple-to-install, delivering reliable flow measurement over a wide dynamic range. Pipe sizes range from 2 to 48". Omega’s FMG-550 magmeters offer frequency or current outputs. The blind transmitter (4 to 20 mA output) is available for long distance signal transmission. The empty pipe detection features a zero flow output when the electrodes are not completely wetted. The frequency output is bi-directional while the 4 to 20 mA output can be set for uni- or bi-directional flow. The 4 to 20 mA output is factory spanned and can be changed using the PC compatible accessory set-up tool.
