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.
