Precise and Errorfree Radiometric Measurements

Radiometric measurements for industrial processes have been around for several decades and they are an important component in the successful performance of critical level, density and flow measurements. Nuclear mea­surement gauges work where conventional measuring technology fails. They offer outstanding measurement results under extreme conditions so that high temperatures, pressures and other difficult ambient and process con­ditions pose no problems. Typical measurement tasks are non-contact level and density measurements in various vessels, bunkers and piping systems, interface measurements in oil separa­tors and moisture measurement. They can also be used as non-contact limit switches. However, every measurement contains errors and radiometric measurements are no exception. The effects of these error influences can nonetheless be eliminated or reduced to an acceptable level, taking into account certain basic conditions and a careful interpretation of the measurement technology.
