The present invention relates to a radar level gauge comprising a reference reflector arranged at a known reference reflector level in a tank. The radar level gauge is controllable between a filling level measuring state and a proof test state. In the proof test state, the radar level gauge is configured to determine a first verification level based on a reference reflector echo resulting from reflection of an electromagnetic transmit signal at the reference reflector; determine a second verification level based on a surface echo resulting from reflection of an electromagnetic transmit signal at the surface of the product; and provide the first verification level and the second verification level to allow determination of a proof test result based on at least the first verification level, the known reference reflector level and the second verification level.

Radar level gauge and methods of testing radar level gauge and system

The present invention relates to reflector arrangement for proof test of a radar level gauge and to a radar level gauge system comprising such a reflector arrangement. The reflector arrangement comprises a pliable elongated member for attachment to a fixed structure in the tank; a weight attachable to the pliable elongated member; and a reflector member for reflecting an electromagnetic signal impinging on the reflector plate. The weight is configured to be coupled to the reflector member in such a way that an orientation of the weight determines an orientation of the reflector member.
