SFM3000 is a digital flow meter especially suitable for high-volume applications. The design of the flow channel results in very low pressure drop through the sensor element, making it highly suitable for medical ventilation and respiration applications.

The SFM3000 bidirectionally measures the flow of air and other non-aggressive gases at rates up to 200slm with excellent accuracy and extremely high speed. It outputs a 14-bit digital signal at a 2kHz update rate. The signal is internally linearized and temperature compensated. Furthermore, the SFM3000 flow meter operates from a 5 Vdc supply voltage and features a digital 2-wire interface, making it easy to connect directly to a microcontroller.

Sensor chip
The SFM3000 flow meter features a fifth-generation silicon sensor chip SF05. In addition to a thermal mass flow sensor element, the chip contains an amplifier, A/D converter, EEPROM memory, digital signal processing circuitry, and interface. Due to seamless integration of
signal acquisition and processing on the single silicon die significant performance and cost benefits are achieved.

Key Features
  • Very low pressure drop < 6mbar @ 200sml
  • Flow range: +/-200slm (bidirectional)
  • Accuracy 1.5% m.v.
  • Ultra fast response time
  • Digitally calibrated & temperature compensated
  • Digital Output (I2C)
