SFM3119-240-CL

SFM3119-240-CL is a low pressure drop digital flow meter. This flow meter is designed for the 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 the 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. Typical applications include ventilation, anesthesia, inspiratory flow sensing and gas mixing.
