Mass Flow Meter SFM3119
Compact digital flow sensor for respiratory devices
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.
Test and evaluate the SFM3119 mass flow meter with the SEK evaluation kit.
First samples of the new SFM3119 mass flow meter will be available in Q1 2021. It will be available in Q2 2021 worldwide via distribution.
