The OEM module Flow-H is designed to work with flow-pressure transducers (flow to differential pressure) like our DP Flow sensors. It can be used to measure the breathing gas flow in respiratory machines.The module is supplying a differential pressure value, which can be used to calculate a corresponding flow value using the characteristic curve of the flow transducer. Moreover, the module delivers a flow value based on a standard curve for DP Flow transducers. The measurement is performed with a high-precision pressure sensor giving a temperature-compensated signal.The unit is equipped with a microvalve for zero offset measurement of the pressure sensor. This feature is working even during gas flow through the flow transducer and without leakage to the ambience.
