Gas Flow Sensor with Low Pressure Drop – GAOTek

Description

Overview

GAOTek Gas Flow Sensor is a 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 flow channel results in a 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 product operates from a 5 Volt supply voltage and features a digital I 2C interface. The measurement results are internally linearized, and temperature compensated. The outstanding performance of this sensor 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.
