          New low-pressure-drop
          digital flow meter

          
Swiss sensor
          manufacturer Sensirion is launching the new digital SFM3000 mass
          flow meter for high-volume applications in medical devices, process
          automation and burner control. The flow channel is designed to
          achieve a very low pressure drop of less than 3mbar through the
          sensor element.



          The flow meter bi-directionally measures the flow of air and
          other non-aggressive gases at rates up to 200slm with high accuracy
          and very high speed. It outputs a 14-bit digital signal at a
          2kHz update rate. The signal is internally linearized and temperature
          compensated. Furthermore, the new mass flow meter operates from
          a 5Vdc supply voltage and features a digital 2-wire interface,
          making it easy to connect directly to a microcontroller.

          
The outstanding
          performance of the SFM3000 gas flow sensor is based on Sensirion's
          patented CMOSens® Technology, which combines the sensor element,
          signal processing and digital calibration on a tiny microchip.
          Gas flow 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 the proven CMOSens®
          technology, the flow meter is suited for high-quality mass production
          and is the ideal choice for demanding and cost-sensitive OEM
          applications in medical ventilation and anesthesia, as well as
          process automation and burner control.
