Abstract
The invention is a radar level gauge comprising a signal generator for generating electromagnetic waves and an antenna for emitting the electromagnetic waves in a container and for receiving electromagnetic waves reflected by the container. The radar level gauge also comprises a safety arrangement for verifying the functional capability or for improving the measuring quality of the radar level gauge, said safety arrangement having a reflector and an adjustment rod and/or a reduction sheath and being suitably designed to adjust the reflector and/or the reduction sheath at least between a first position and a second position, in which the reflector reflects the electromagnetic waves in a reduced manner. The adjustment rod acts on the reflector and/or the reduction sheath in a contactless manner.
