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.
