摘要：Method of measuring the injection quantity and the injection rate of an injectionvalve for liquids, preferably for liquid fuel, in which the injection valve (3) injects the liquidinto a liquid-filled measuring volume (1), wherein the measuring volume (1) is closed offall round and a pressure sensor (20) is arranged in the measuring volume. The speed ofsound is determined from a separate measurement and thus the total injection quantity(Δm) and/or the time characteristic of the injection rate (r(t)) is calculated. The devicecomprises a measuring volume (1), an injection valve (3) which projects with at least oneinjection opening (12) into the measuring volume (1), and a sound transducer (30) whichcan emit a sound signal and receive its echo.
