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
