ABSTRACT:
A device is used for measuring the injection quantity of injection nozzles. It includes a measuring chamber to which the injection nozzle can be coupled. In addition, a detection device is provided, which detects a state change of the testing fluid in the measuring chamber due to an injection by the injection nozzle. In order to be able to measure the injection quantity without wear and in a highly precise manner, the invention provides that the detection device has a capacitor, whose one electrode is comprised of an electrically conductive fluid, which is at least partially contained in a volume connected to the measuring chamber. The processing unit is connected to the capacitor in such a way that it can detect a change in its capacitance, which is produced by a movement of the electrically conductive fluid.
