Nuclear Gauging System
2. Density gauge:
▪ Use to measure density of materials.
▪ Use in a broad range of industries e.g. gas/oil production, chemical and
hydrocarbon processing, pulp and paper mill, mining and food industry.
▪ It works on transmission principle utilizing a gamma (Cs-137 or Co-60) or a
beta source (Sr-90) with one or more detectors.
▪ Higher density materials attenuate more radiation and the reduction is
proportional to the density.
