The AFM3000 medical flow sensor is Aosong’s digital flow meter designed specifically for ventilator applications. It measures the flow rate of air, oxygen and other 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 Volt supply 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.
