The flow of air and oxygen at rates from -10slm to 240slm is measured with excellent accuracy and extremely high speed. It outputs a 16-bit digital signal at a 2kHz update rate. The signal is internally linearized and temperature compensated. Furthermore, the SFM3019 flow meter operates from a 3.3V to 5 Vdc supply voltage and features a digital two-wire interface, making it easy to connect directly to a microcontroller.

As part of the SFM3xxx platform, the SFM3019 is the suitable choice for inspiratory flow measurements for high-volume applications in which cost efficiency is the priority.The outstanding performance of the SFM3019 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.
