Sensirion (Westlake Village, CA) has launched the 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 bidirectionally measures the flow of air and other non-aggressive gases at rates up to 200slm with high accuracy and very low speed. It outputs a 14-bit digital signal at a 2kHz update rate. The signal is internally linearized and temperature compensated. It operates from a 5 VDC supply voltage and features a digital 2-wire interface, making it easy to connect directly to a microcontroller.
