Flushable device for measuring flow processes of fluids

Abstract

A device for measuring flow processes of fluids. The device includes an inlet, an outlet, a drive unit, a positive displacement flow meter which is driven by the drive unit, the positive displacement flow meter including a positive displacement chamber, a supply duct which fluidically connects the positive displacement chamber to the inlet, a discharge duct which fluidically connects the positive displacement chamber to the outlet, a bypass which bypasses the positive displacement flow meter, a differential pressure sensor arranged in the bypass, and an evaluation and control unit which provides a control of the positive displacement flow meter based on a differential pressure applied to the differential pressure sensor. The supply duct and the discharge duct each rise in a fluid flow direction.
