Abstract
A level or density of a medium in a tank is radiometrically measured by detecting the light flashes generated by a scintillator with an array of photodiodes. Corresponding voltage pulses are summed up and analyzed with respect to their relevance before they are used for determining the level or the density of the medium.
Claims13
A measurement system for determining at least one of a radiometric level and a density of a medium, comprising:
- a converter at least partially converting ionizing first radiation that penetrates the medium into electromagnetic second radiation;
- a photodiode at least partially converting the second radiation into a voltage pulse;
- and
- an evaluation unit determining at least one of the level and the density based on a number of generated voltage pulses.
