OMEGA FMG3000-FMG3100-Series Fixed Depth, Polypropylene, Insertion Electromagnetic Flow Meter

Description of OMEGA FMG3000-FMG3100

The FMG3000 Series magmeters are insertion-style magnetic flow sensors with no moving parts. All models are constructed of corrosion-resistant materials to provide long-term reliability with minimal maintenance costs. When these magmeters are used with OMEGA’s comprehensive line of installation fittings, sensor alignment and insertion depth are automatic. Fittings are required for installation. Please refer to accessories below.

These versatile, simple-to-install flowmeters deliver accurate flow measurement over a wide dynamic range in pipe sizes ranging from 0.5 to 8″, satisfying the requirements of many diverse applications. FMG3000 Series magmeters offer a variety of output options for use with OMEGA flow instrumentation that has a frequency or 4 to 20 mA output. Flow velocity measurement is compensated for temperature via an integrated temperature sensor.
