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.

Abstract: An apparatus for measuring hydraulic flow quantities and leaks in a specimen, including a measuring section to which the specimen is coupled and a capacitive sensor disposed in the measuring section. The measuring section can be acted upon both by at least one measurement medium and by at least one pressure medium. For generating a pressure acting on the measurement medium an inlet/outlet for the measurement medium is embodied on a side of the measuring section remote from the specimen, and an inlet/outlet for the pressure medium is disposed directly on the measuring section, on a side of the measuring section toward the specimen.
