The invention relates to a radar level gauge (1) comprising a signal generator for generating electromagnetic waves and an antenna (3) for emitting the electromagnetic waves in a container (4) and for receiving electromagnetic waves reflected by the container (4). The radar level gauge also comprises a safety device (5) for verifying the functional capability or for improving the measuring quality of the radar level gauge (1), said safety device (5) having a reflector (7) and an adjustment device (9) and/or a reduction device (15) and being suitably designed to adjust the reflector (7) and/or the reduction device (15) at least between a first position (I), in which the reflector reflects the electromagnetic waves and a second position (II), in which the reflector reflects the electromagnetic waves in a reduced manner. The safety device also has at least one additional sensor (11) for detecting a measured variable in the container (4). |
