STAINLESS STEEL GAS MASS FLOWMETERS
AND CONTROLLERS
For Clean Gases
FMA2800 Series
U Economical
U Compact and Lightweight
U Power Supply Included
The FMA2700/FMA2800 Series
electronic mass flowmeters
and FMA3700/FMA3800 mass
flow controllers provide high
performance and versatility.
Omega’s new in-line series features
a “flow-through” zero dead space
design for quicker processing and
lower contamination.
Available with onboard display and
wall-mounted power supply, the
in-line series is ideal for laboratory
and test applications. Compact,
lightweight, and economical,
the FMA2700/FMA2800 Series
electronic mass flowmeters
and FMA3700/FMA3800 mass
flow controllers are perfect for
applications that require an all
stainless steel construction.
