Abstract
A radiometric measuring device for determining an intensity of pulses of an interference signal from an external radiation source, wherein the radiometric measuring device carries out fill level or limit level determination of a filling material in a container. The radiometric measuring device has a detector which is configured to receive pulses of a useful signal modulated with a modulation frequency from a gamma emitter and additionally pulses of the interference signal from the external radiation source. Further, the measuring device comprises an averager configured to output a first count rate of the pulses at an averager output, and a bandpass system comprising a bandpass with adjustable passband frequency range configured to output a second count rate of the pulses at a bandpass system output. The measuring device further comprises a subtractor adapted to form a differential count rate between the first count rate and the second count rate.
