Abstract
The invention relates to a device for determining and/or monitoring the density and/or the level (L) of a filling material in a container. A transmitting unit which emits radioactive radiation and a receiving unit which is arranged in such a way that it receives the radioactive radiation or the secondary radiation that is produced by the interaction of the radioactive radiation with the filling material are provided. A regulating/evaluating unit which determines the density and/or the level of the filling material in the container using the measuring data that is supplied by the receiving unit is also provided. The aim of the invention is to provide a device which enables the level or the density of a filling material in a container to be measured reliably. To this end, the receiving unit consists of individual detector units. These detector units are positioned at different distances from the floor of the container, so that each detector unit directly or indirectly, essentially detects the proportion of radiation that passes.
