Abstract (en)
[origin: DE19709422A1] The invention relates to a device for measuring hydraulic discharge and leakage in a test piece, comprising a measuring section configured as an inflow pipe approximately perpendicular to the test piece and a capacitive sensor located on the measuring section. Said sensor can be impinged upon by both at least one measuring medium and at least one other medium (pressure medium) designed to generate a pressure acting on the measuring medium. The invention aims to improve said device in such a way that it is possible to carry out precise measurements of discharge volumes and leakages using simple technology. To this end, the invention provides for the test piece to be coupled directly to the measuring section.
