Abstract
A filling level measuring device operating with microwaves and to be fastened on a container (3) is provided, the device having a housing (11) and a rod-shaped antenna (7) pointing into the container (3) and the device being designed such that the antenna (7) does not transmit or receive microwaves in the region of a measuring device fastening and the transmitted power is not impaired by condensate or moisture. According to a first solution variant, the antenna (7) is fastened in the housing (11) and a section of the antenna (7) in the region of the measuring device fastening is surrounded by a metallic sleeve (8). According to a second solution variant, a sleeve (8a) in which the antenna (7) is fastened is formed onto the housing (11).
