McMillan”s Model 209 mass flow sensors are capable of measuring gases as low as 0-50 L/minute or as high as 0-500 L/minute. Repeatable results are achieved using a patented thermal mass flow sensor design. The design minimizes zero drift while maintaining fast response and linear outputs. The flow sensors are suitable for a variety of industrial, commercial, laboratory, and OEM applications. Some sample applications include furnace flow control, online gas blending, regulation of sample gas streams, and precise gas injection systems. Aluminum construction with NPT ports is standard. An analog output is provided for remote data monitoring.
