The FMA-A2000 Series electronic mass ﬂowmeters/ controllers provide high performance, versatility, and state-of-the-art design in one compact package. The FMA-A2000 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 have linear 0 to 5 Vdc and 4 to 20 mA output.

The FMA-A2000 measures the mass ﬂow rate of gases in 24 ranges from 0 to 100 SLM. For the complete listing, refer to the range table on page D-20. The FMA-A2000 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 ﬂow rate. A command signal can be supplied either by the internal setpoint pot or by a 0 to 5 Vdc external source.

Note: 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.

Specify gas, inlet/outlet pressure, temperature.

For 5-point NIST calibration certificate, add suffix “-NIST5” to model number, no additional charge. For 10-point NIST calibration certificate, add suffix “-NIST10” to model number for additional cost. Ordering Examples: FMA-A2316, mass flowmeter with display, calibrated for nitrogen at

20 psig inlet, room temperature for 0 to 45 SLM. ∆P: 5 to 20 psi. FMA-A2102-SS, 316 stainless steel body mass flowmeter without display, 0 to 50 SCCM.
