The FMA-A2100/2200/2300/2400 Series Electronic Mass Flow meters & 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 flow rate 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 non-corrosive 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.

At this time the FMA-A2104, FMA-A2114, and FMA-A2115 do not come standard with a NIST certificate. For a 5-point NIST certificate for these mass flow meters only, add suffix "-NIST" to the model number, no additional cost.

For a 10-point NIST certificate, add suffix "-NIST10" to the part number; contact sales for additional pricing.

Calibrations are performed at at an ambient temperature of 20°C only.

All controller flow ranges specified are for Nitrogen or air at 1.38 bar (20; psig). When used for other gases, a correlation factor is needed to determine the flow rate.

For non-standard calibrations, specify the desired gas and pressure in order comments.

Meter flow rates are specified for Nitrogen at 1 bar absolute (14.7 psia).

** For optional 316 SS body meters, add "-SS" to model number; Consult sales for additional pricing
