SFM3119 Low-Pressure Drop Flow Meter

Sensirion’s SFM3119 flow meter sensor is designed for mass flow measurement in ventilators. It measures the flow rate of air, oxygen, and non-aggressive gases with superb accuracy. A special design of the flow channel results in very low pressure drop through the flow body of the sensor making it extremely suitable for medical ventilation and respiratory applications.

The outstanding performance of these sensors is based on Sensirion’s patented CMOSens® sensor technology, which combines a thermal sensor element, signal processing, and digital calibration on a single microchip. This assures very fast signal processing. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.
