Bi-directional low-pressure-drop digital gas flow meter takes rates up to 200 standard liters per minute

June 14, 2012 // By Julien Happich
The digital SFM3000 mass flow meter from Sensirion is designed 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 (standard liters per minute) 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. What's more, the sensor operates from a 5Vdc supply voltage and features a digital 2-wire interface, mak-ing it easy to connect directly to a microcontroller.
