1.  Product Summary

The AFM3000 medical flow sensor is Aosong’s digital flow meter designed specifically for ventilator applications. It measures the flow rate of air, oxygen andother non-aggressive gases with superb accuracy. A special design of the mass flow sensor  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 AFM3000 operates from a 5 Voltsupply voltage and features a digital I²C interface. The measurement results are internally linearized and temperature compensated.
The outstanding performance of this mass flow sensor is based on Aosong’s sensor technology,which combines a thermal sensor chip and a high-performance integrated 24-bit AD acquisition CMOS microprocessor. The flow rate of the gas is measured by a thermal sensor element which assures very fast signal processing time and bidirectional measurement with best-in-class accuracy.
