FMA3100 Series mass flow sensors represent a breakthrough in mass flow sensor technology. State-of-the-art electronics, a compact mechanical design, and mass production tooling concepts are combined into one high- performance, cost effective product. The gas flow sensor is suitable for many OEM applications. A 0 to 5 Vdc linear output is standard.

Using the basic FMA3100 thermal mass flow sensor, the FMA3200 mass flow controllers offer accurate, stable control of gas flows in a compact package. In power-off mode, the flow control valve is closed with a minimal leak rate. This cost-effective controller is ideal for many OEM applications, with a 0 to 5 Vdc linear output and a 0 to 5 Vdc control input.

The FMA3300s combine the features of the FMA3100 with an adjustable 3½ digit LCD digital display meter for viewing flow rate in engineering units (i.e., mL/min or L/min). These compact flowmeters have proved effective in many laboratory applications.

Do the FMA3200 series mass flow controllers (with both input and output) on sale anymore? I cannot find it on your website. I need a controller without LCD display. Thank you.

Asked by: Chufan
Thank you for your inquiry. The FMA3200 series controller have been discontinued. An alternative controller you could look at is the FMA5400 series. It does not have a display.

Looking at FMA3104ST in the range of 20-200 sccm, will trace amounts of ammonia gas harm this?

Asked by: TK28
Thank you for your inquiry! These units are not intended for use wit ammonia and we do not have tested data for the threshold at which damage will occur. If ammonia will be present we suggest using the FMA-1600A-LSS series intended for corrosive gases

Can the FMA3102 control the flowrate of a gas? Or does it just measure the flowrate?

Asked by: EvieH
Thank you for your inquiry. The FMA3102 is mass flow meter, meaning it only measures the flow rate of gas.
