Product Specs

  • Repeatability ±1.5% FS

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.

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.
