Abstract
The present invention relates to a fluid flow measuring device. The device includes a fluid flow having at least one of a volume flow rate and a mass flow rate. At least one spring element is included, which is exposed to the fluid flow, such that the spring element is elastically displaceable in at least one of a ferromagnetic and an electrically conductive mobile region depending on the dynamic pressure acting thereon with an eddy current sensor arranged stationarily. The eddy current sensor generates a measurement signal that is correlated with a distance between the eddy current sensor and the mobile region. The distance varies with the dynamic pressure-related displacement of the mobile region, and at least one temperature sensor is included, the temperature sensor measures an actual temperature of the fluid flow.
