New Mass Flow Meter SFM3119


Compact flow sensor for respiratory devices


The SFM3119 is a compact digital flow sensor. Compared to its predecessor SFM3100, the SFM3119 flow sensor comes with a digital I²C output, and improved specifications and manufacturing throughput. It is a highly stable and precise measurement solution and can be easily integrated into existing devices. The flow sensor is particularly suitable for inspiratory flow sensing in ventilators or anesthesia devices as it by default supports mixing of oxygen and air.
