Abstract:
PCT No. PCT/DE94/01229 Sec. 371 Date Jun. 20, 1995 Sec. 102(e) Date Jun. 20, 1995 PCT Filed Oct. 17, 1994 PCT Pub. No. WO95/12113 PCT Pub. Date May 4, 1995To measure the level of contents in metallic tanks by means of short electromagnetic waves, it is proposed to mount the complete level measuring assembly, including the horn antenna, outside the tank. The transmitted waves are projected through an opening in the tank wall toward the surface of the medium whose level is to be measured. The opening is closed with a glass or ceramic plate. To distinguish the useful signal within the unwanted echos caused by multiple reflections of the electromagnetic waves at the glass or ceramic plate, a damping layer of a conventional damping material is interposed between the microwave coupling element and the surface of the glass or ceramic plate. To achieve an optimum signal-to-noise ratio, the damping coefficient is fixable and the distance between the level measuring assembly and the surface of the glass or ceramic plate is adjustable in the axial direction of the opening.
