The SFM3003 mass flow meter is Sensirion’s next-generation flow meter. Technically it is based on the SFM3019 meter that was brought onto the market during the Covid-19 pandemic to provide high volumes of flow meters for inspiratory flow measurements in medical ventilators. Compared to the SFM3019, the SFM3003 comes with a wider flow range as well as improved specifications.

The flow of air, oxygen and mixtures thereof at rates between -30 and 300 slm is measured with excellent accuracy, reliability and long-term stability, and no recalibration is needed. The SFM3003 outputs an easily integrable digital I2C interface. The signal is internally linearized and temperature compensated. Furthermore, the SFM3003 flow meter has a very low pressure drop, ultra-fast response time and optimal signal-to-noise ratio.

As part of the SFM3xxx platform, the SFM3003 is a versatile sensor solution for many different high-volume applications in which cost efficiency is the priority. The outstanding performance of the SFM3003 sensor is based on Sensirion’s patented CMOSens® Technology, which combines the sensor element, signal processing and digital calibration on a tiny microchip. The gas is measured by a thermal sensor element to provide an extended dynamic range and enhanced long-term stability compared to other flow-measuring technologies. Thanks to this proven CMOSens® Technology, the flow meter is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.
