The FMG70 series has been discontinued. Please see the FMG70B Series as a possible alternative or contact our Flow Engineering department.

The FMG70 series from OMEGA is a trio of extremely compact, low cost, inductive magnetic flow sensors. This new product line allows a unique and highly reliable measuring technique to be introduced into areas of process control previously considered not possible.

Changes of temperature, density, viscosity, concentration or electrical conductivity (minimum conductivity of 50 ..µs/cm) of the fluid do not affect the output signal.

FMG70 series can be used in areas where flow sensors with moving parts e. g. paddle wheel sensors, cannot be applied due to contamination / particulate in the media. The sensor is intended for continuously measuring of flow rates or for dosing / batching of electrically conductive liquids (minimum conductivity 50 µs/cm). The output signal frequency (or current) is proportional to the flow. Two options are available for output signals, frequency or analog (-A Models).
