Beschreibung
Zusammenfassung:	An apparatus (10) for measuring the injection quantity of injection systems (32), in particular for internal combustion engines in motor vehicles and especially in production testing, includes a measurement chamber (45). A connecting device (28) is also provided, by which at least one injection system (32) can be made to communicate with the measurement chamber (45) in pressuretight fashion. A piston (40) is passed through a wall of the measurement chamber (45). A detection device (58) is also provided, with which a motion of the piston (40) can be detected. To increase the measurement accuracy of the apparatus (10), it is proposed that the detection device (58) function in noncontacting fashion.
