Compact Analog Mass Flow Meter

Sensirion introduces the SFM3100 analog mass flow meter for applications in medical respiration and anesthesia. The mass flow meter has a compact design and can be easily integrated into existing devices. There is a temperature sensor in the gas channel of the flow meter. This enables precise temperature compensation and obviates the need to integrate a dedicated temperature sensor. The product returns ananalog output signal and measures the flow rates of air and other non-aggressive gases between -24 and +240 slm. It can also detect negative flow ranges, thereby recognizing errors or impeded flows. At the same time, multiple gases are compensated with great precision. The flow rates and signal characteristics of the sensor can be customized to meet customer-specific requirements. The fully calibrated and temperature-compensated mass flow meter also boats a low pressure drop and is free of zero-point drift.
