Abstract:
1. Level meter comprising: a waveguide for guiding an electromagnetic wave, such that the waveguide is designed as a hollow conductor and has a terminal section; a wave adapter of a dielectrical material, such that the wave adapter has an outer circumferential area and partially projects with this outer circumferential area into a hole in the terminal section of the waveguide and partially protrudes from this terminal section, and such that the wave adapter has dimensions that allow it to adapt the wave transition of a wave leaving or entering the terminal section of the waveguide; and a metallized part comprising a metallic transitional material in an area between the wave adapter and the waveguide, wherein the metallized part extends over an area greater than an area of direct contact between the outer circumference of the wave adapter and the waveguide.
