摘要

Method (1) for operating a non-contact ultrasound or radar level gauge (2) with at least one free-radiating transmitter (3), at least one receiver (5) and at least one evaluation unit (8) comprising the following steps: Emitting (100) a transmission signal (4) by the transmitter (3), Receiving (101) a reflection signal (7) reflected by a reflector (6) by the receiver (5), Evaluating (102) the transmission signal (4) and / or the reflection signal (7) by the evaluation unit (8), characterized, in that the evaluation unit (8) detects (103) a frequency shift between the transmission signal (4) and the reflection signal (103) and, by evaluating the determined frequency shift or a variable derived from the determined frequency shift, detects a filling process (104) in which a filling flow ( 9) at least partially passes through the transmission signal (4), wherein the evaluation unit (8) determines the reflector speed (105) from the determined frequency shift and detects the filling process by a comparison (106) of the reflector speed with a defined speed limit value.
