Concentration measurement
The Gammapilot FMG50 determines the concentration indirectly via a density measurement. A
linearization table consisting of up to 32 "density - concentration" value pairs can be entered for this
calculation. The solids content of liquids, for example, can be measured in this way (percentage of
volume or weight).

Concentration measurement with radiating media
The Gammapilot FMG50 calculates the concentration of the medium from the intensity of the
radiation that is emitted by the medium itself.
A source container and radiation source are not needed for the measurement
