Abstract
A drop-detection device () for the detection of drops (TR) that escape from a nozzle of a metering valve (DV), preferably a micro-metering valve, is described. The drop-detection device () comprises a signal-generation unit (), which is configured to produce a carrier signal (TS) with a defined pulse frequency. In addition, the drop-detection device () has a modulation unit () which is configured to generate a modulated signal (MS) due to a physical interaction of the carrier signal (TS) with a drop to be detected (TR), Furthermore, the drop-detection device () has an evaluation unit (), which is configured to determine if a drop (TR) has been dispensed by the metering valve (DV) based on the measurement signal (MS) under consideration of the defined pulse frequency. A method () of detecting a drop (TR) of a metering valve (DV) is also described.
