摘要
A method for operating a contactless ultrasound or radar fill level measuring device having at least one open distribution transmitter, at least one receiver and at least one evaluation unit having the following steps: emitting a transmitter signal by the transmitter, receiving a reflection signal reflected on a reflector by the receiver, evaluating the transmitter signal and/or the reflection signal with the evaluation unit which identifies a frequency shift between the transmitter signal and the reflection signal. By evaluating the determined frequency shift or a variable derived from the determined frequency shift, a filling event is detected, in which a filling stream at least partially passes through the transmitter signal. Furthermore, a contactless ultrasound or radar fill level measuring device which performs this method.
