The FMA-A2100/2200/2300/2400 Series Electronic Mass Flowmeters/ Controllers provide high performance,
versatility and state-of-the-art design in one compact package. The FMA-A2100/ 2200/2300/2400 uses
capillary-type thermal technology to directly measure mass flow of gases. No temperature, pressure,
or square root corrections are required. The FMA-A2300/2400 Series comes with an LCD display, and all
models come with linear 0-5 and 4-20 mA output.
The FMA-A2100/2200/2300/2400 measures the mass flowrate of gases in 24 ranges from 0-10 SCCM to 0-100
SLM. For the complete listing, refer to the range table below. The FMA-A2100/2200/ 2300/2400 Series
is compatible with most noncorrosive gases. The user is advised to check the wetted materials against
gas compatibility.
OMEGA’s Mass Flow Controllers use an internal electromagnetic proportional valve to control the mass
flowrate. A command signal can be supplied either by the internal setpoint pot or by a 0-5 Vdc external
source.

FMA-A2200-SS-(**) and FMA-A2400-SS-(**) controllers have a stainless steel body (with 1/4" compression fittings)standard.
† All dollar amounts on this site are shown in Singapore currency.
Note: Comes complete with 9-pin sub-D connector, power supply, 5-point NIST certificate, and operator's manual.
For a 10-point NIST certificate, add suffix "-NIST10" to the part number; add $125 to price.
***PRODUCT PURCHASED PRIOR TO JANUARY 1, 2012 WILL NOT INCLUDE A NIST CALIBRATION WITH POINTS UNLESS SPECIFIED AT THE TIME OF THE ORIGINAL ORDER. CALIBRATIONS WITH POINTS PRIOR TO JANUARY 1, 2012 WERE AN ADDITIONAL COST.
Calibrations done at ambient (20°C or 70°F) temperature only.
CONTROLLERS: All controller flow ranges specified are for Nitrogen or air at 20; psig when used for other gases, a correlation factor is needed to determine the flow rate.
For non-standard calibrations, replace controller suffix "-(**)" with the desired gas and pressure.
METERS: Meter flow rates are specified at Nitrogen 14.7 psia. (OPTIONS SHOWN IN THIS "NOTE" ABOVE ARE PRICED IN US$)
