High-precision, configurable, fast, multi-gas flow sensor
The SFM5400 mass flow meter measures mass flows with outstanding accuracy (errors < 1%), long-term stability and repeatability and covers an impressively wide dynamic measurement range. The SFM5400 is made of metal and highly configurable. The sensor signal is directly converted into a digital, completely calibrated and temperature-compensated signal on the chip. Multiple gas calibrations can be stored on a single device. Additionally, the flow meter can check whether the activated gas calibration matches the actual gas present. The SFM5400's versatility makes it the ideal solution for industrial and medical applications. The outstanding performance of the SFM5400 mass flow meter is based on the innovative CMOSens® Technology, which integrates the high-precision sensor element and the analog and digital processing electronics on a single CMOS silicon chip. Combined with high-quality materials, the result is a durably stable, extremely fast and highly precise mass flow meter. The SFM5400 mass flow meter is the valve-free version of the SFC5400 mass flow controller. The SFC5400 mass flow controller has the same performance characteristics as the mass flow meter and is used in similar applications, and the two products can be ideally combined. You can find further information and detailed specifications about the mass flow controller on the SFC5400 website.
