Abstract
An arrangement for measuring fill levels of fill substances located in containers with a single fill-level measuring device operating according to the travel time principle, and arranged removed from the measuring locations at which a fill level is to be measured and having an antenna for directed sending of microwaves and for receiving microwaves. The arrangement includes: a mirror arrangement, which has, arranged at a measuring location above the fill substance, at least one mirror, which transmits, to the surface of the fill substance, microwaves sent from the antenna in their transmission direction and which transmits, back to the antenna, their echoes reflected on the surface of the fill substance; and a measuring device electronics, which is fed, in measurement operation, received signals received with the antenna, and which, on the basis of the received signals, ascertains the travel times of the microwaves reflected at the measuring locations on the surface of the fill substance and ascertains therefrom, on the basis of the positions of the mirrors arranged above the fill substance at the measuring locations, the fill levels at the measuring locations.
