ABSTRACT:
The present invention relates to a radar level measuring device for non-contact measurement of a level of a product in a container. The device comprises a flange which is mounted on the container in such a way that a lead-through of the flange at least partly covers an opening in the container. The device further comprises a waveguide part, insertable into the flange. When inserted, the insertable waveguide part is arranged to come to a stop at a distance (D) from the surface of the flange intended to face the container, along which distance (D), a waveguide is formed, forming a continuous waveguide together with the insertable waveguide part when inserted.
