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.

Rated 5 out of 5 by from Great for QC or R&D This is our 2nd flow meter of this style. The readings from old one match the new one. Good gage repeatability. Works great for checking air pumps. The display is good when you don't want hook up the analog output. Just keep the water drops away and make sure that you warm it up for 5 minutes.

Hi I have been using the FMA-A2310 for awhile and i would like to know what type of sealant is the best for the plastic threads.

We have a mass flow meter that displays up to 500 sccm, on a regulated 250 psi line. we wonder about damaging the instrument during cylinder changes, (filling the line and venting), should we install a bypass valve, a restrictor or will it take the hit?

Asked by: Nicolas
Thank you for your inquiry about the mass flow meter. That is a good suggestion to have a bypass the pressure away from the flow meter.

We have an FMA-A2307 that after it turns on and eventually zeros, drifts between 0.01 to -0.02. We had it calibrated one year ago. When we put a flow on it which ranges from 0 to 0.30 LPM, it takes a while to get to a constant number.

Asked by: bobbygct
Thank you for your inquiry! Yearly calibrations are recommended for these units and if this is a recent development another calibration may be needed. More details may be needed to diagnose this issue. Please contact us at flow@omega.com so that we can troubleshoot this issue.
