AFM3020 Gas Mass Flow Sensor

1. Product Summary

The AFM3020 sensor is an Aosong digital flow meter specially designed for ventilator 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 AFM3020 operates from a 5 Volt supply voltage and features a digital I2C interface. The measurement result is output after internal calibration and temperature compensation. The outstanding performance of this sensor is based on Aosong sensor technology,which combines a thermal sensor chip and a high-performance integrated 24-bit AD acquisition CMOS microprocessor. The thermal sensor chip measures the gas flow, ensuring very fast signal processing time and higher accuracy than similar products.
