ABSTRACT:
A device for measuring flow rate of a flowing medium in a pipe having a throttling device received therein, and a meter for measuring pressure differential connected to the throttling device, including a measuring device for determining density of the medium being disposed in the flowing medium, the pressure differential meter and the measuring device for determining the density of the medium being connected to an evaluation unit for determining the flow rate from the pressure differential in the flowing medium and the density of the medium, the measuring device for determining the density of the medium being located at a section of the throttling device which has a uniformly smaller diameter than that of the pipe.
