SFM3119
Compact digital flow sensor, 240 slm
The SFM3119 is a compact digital flow meter. It is the successor of the SFM3100 mass flow meter. Compared to its predecessor, the SFM3119 comes with a digital I²C output as well as improved specifications. The SFM3119 mass flow meter is highly accurate and fast at flows of air, oxygen and mixtures thereof between -10 and 240 slm. It has a compact design and can be easily integrated into existing devices. The signal is internally linearized and temperature compensated. Furthermore, the SFM3119 flow meter has a low pressure drop. Like all Sensirion flow sensors, the SFM3119 mass flow sensor is based on the patented CMOSens® Technology, which combines the sensor and analysis electronics on a single microchip. The result is a highly stable and precise system for demanding and cost-sensitive applications. The SFM3119 is particularly suitable for inspiratory flow sensing in applications like ventilation or anesthesia as well as for mixing oxygen and air to a very precise degree.
