The FMA5400A/5500A Series electronic gas mass flow controllers provide for controlling the flow of a wide variety of gases from 0-10 SCCM up to 100 SLM. Utilizing heat transfer through a heated tube to measure molecular gas flow rate, the FMA5400A/5500A provides measurement of direct gas mass flow rate, without the need to compensate for variations in gas temperature or pressure (within stated limits). They are available in an economical aluminum/brass construction for typical gas flows and a 316 SS construction for applications requiring more corrosion resistance. The FMA5400A series without integral display is supplied with both an analog 0-5 Vdc and 4 to 20 mA output for remote monitoring; the FMA5500A series has both an integral 3-1/2 digit display and analog output. The display is tiltable over 90 degrees for viewing convenience. The display is calibrated standard to read out directly in SCCM or SLM for nitrogen (other gas calibrations available on special order).
The FMA5400A/5500A mass flow controllers feature a built-in normally-closed electromagnetic valve for maintaining a constant flow rate regardless of variations in inlet or outlet pressures. The setpoint is controlled either locally via a potentiometer accessible through an access window in the case or remotely via an analog 0-5 Vdc or 4-20 mA signal (field selectable). The FMA5400A/5500A series require 12 to 26 Vdc power @ 800 mA maximum, which can be supplied by the FMA545PW wall plug-in socket power supply. 12 to 15 Vdc power @ 800 mA maximum (Sizes 43,44, and 45 ONLY). Model number FMA545C (supplied separately) provides a mating 15-pin “D” connector with 8 feet of shielded cable for accessing the analog output signals and power input connections. The LCD supplied with the FMA5500A series is connected to the lower electronics via a modular plug. The LCD can be remotely located by purchasing an FMA18RC remote cable assembly–you must then build your own assembly for panel mounting the LCD.

Good MFC but poor customer support
Beware!! they don't sell it with power cable so make sure you buy it! The technical support person is not thorough and will try not to understand your needs. The return policy is also not good. However, it is a good MFC with precise control.

You get what you pay for
Works exactly as expected, like all Omega products.

Love them
Great MFCs at a quick turn around, we use them in many applications. Some times in multiple flows.

Difficult to work with and incomplete manual
Mass flow controller is not functional with shop air.
