ABSTRACT:
The invention relates to a level meter with a waveguide for guiding an electromagnetic wave, such that the waveguide is designed as a hollow conductor and has a forward terminal section; with 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 with a metallic transitional material in an area between the wave adapter and the waveguide, such that the transitional material assumes the form of a metallized part that extends over an area greater than area of direct contact between the outer circumference of the wave adapter and the waveguide.
