Abstract

In order to improve a device for measuring hydraulic flow quantities and leaks in a specimen, including a measurement path, embodied as an approximately vertically extending lead line to the specimen, and a capacitor sensor, which is disposed in the measurement path and can be acted upon both by at least one measuring medium and by at least one medium for generating a pressure (pressure medium) on the measuring medium in such a way that precise measurements of flow quantities and leaks are possible in a technically easily achieved way, the specimen is coupled directly to the measurement path.
