The FMG70B Series from OMEGA is a trio of extremely compact, low cost, inductive magnetic flow sensors. This 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.

FMG70B 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 S/cm). The output signal frequency (or current) is proportional to the flow. Two options are available for output signals, frequency or analog (-A models).

Is there a 4-20mA version of the FMG71B available? The datasheet says there is but the website shows no such thing.

Asked by: TMRW
Yes. The part number with the 4-20 mA output is FMG71B-A.
Answered by: ASE HPO
Date published: 2019-10-09

Is the 4-20mA version (FMG71B-A) a 2-wire or 3-wire? The data sheet, the manual and the pinout diagram on the part do not make this distinction clear.
