ABSTRACT:
The apparatus for measuring a hydraulic fluid flow rate and/or leak rate through an object, particularly a valve, includes an approximately vertical measurement tube, a capacitive sensor mounted on the measurement tube, an equalization vessel extending vertically next to the measurement tube, and a source of hydraulic fluid connected to the equalization vessel and the measurement tube below the capacitive sensor and a source of a pneumatic medium connected to both the equalization vessel and the measurement tube above the capacitive sensor. Hydraulic and pneumatic valves are also provided so that hydraulic fluid can be accommodated in a lower part of the equalization vessel and pneumatic medium in an upper part. A connector tube with a connector valve is connected to the equalization vessel at about the level of the capacitive sensor so that the level of hydraulic fluid can be set at the capacitive sensor in the measurement tube at the beginning of the measurement. The capacitance rate of change is a measure of the hydraulic fluid flow or leak rate.
