    摘要： 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.

    摘要： A method is based on measuring a distance to a reference reflector arranged at a known distance, in order to calibrate and/or monitor a coherent frequency modulation, continuous wave radar, fill-level measuring device, wherein the reference reflector can be reliably identified. To this end, a reference reflector executing oscillations toward the fill-level measuring device with an oscillation frequency is used, which is inserted in the beam path of periodically linearly frequency modulated transmission signals transmitted from the fill-level measuring device. The fill-level measuring device receives fractions of the transmission signals reflected back on reflectors in the container and records based on these received signals and their time correlation relative to the respectively associated transmission signal for each received signal an echo function, which shows the amplitudes of the received signal as a function of the associated position of the associated reflector. Based on the time change of a plurality of sequentially recorded echo functions and the oscillation frequency of the reference reflector, the position of the reference reflector in the echo functions is identified and its reference reflector position determined.
