SFM3000-200C

SFM3000-200C is a SFM3000 series low pressure drop digital flow meter designed for high-volume applications. It measures the flow rate of air, oxygen and other 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 very demanding applications, such as medical ventilation and respiratory applications. The SFM3000 operates from a 5 Volt supply voltage and features a digital 2-wire I²C interface. The measurement result is internally linearized and temperature compensated. The outstanding performance of this sensor is based on Sensirion’s patented CMOSens® sensor technology, which combines the sensor element, signal processing and digital calibration on a single microchip. Application includes medical, process automation, burner control, fuel cell control, spectroscopy, environment monitoring, laboratory.
