1.4 Intended use
Purpose of device components
The FWE200DH measuring system is used exclusively for continuous measurement of dust
concentrations in wet gases. In some applications in this area of application, deposits can
occur which can constrict or clog the lines and components carrying the sample gas (e.g. in
the production of fertilizers or glass wool). The equipment variant of the FWE200DH has a
water back purge unit. This ensures that recurring water purging of the lines and compo-
nents carrying the sample gas dissolves water-soluble deposits and flushes these back into
the sample gas duct.
