DURAG GROUP Extractive Measurement

Extractive measurement is the solution for process gases with moisture content above 95 percent. It is also suitable for all flue gases with temperatures below the dew point of water and acids. Dust concentrations in flue gases containing liquid from cleaning by means of wet scrubbers must also be measured this way. For this purpose, a probe is used to continuously extract flue gas from the duct, diluted and heated. This produces a dry flue gas whose dust concentration is measured in the measuring device outside the duct using the scattered light principle.
