Abstract
The invention relates to a process and a device for sampling a solids-containing flowing medium, such as the circulating water in a papermaking machine. According to the process, a filter 2 is used to separate off a filtrate which is at least essentially free of solids and which can be utilized for analysis. According to the invention, the sampling is effected by first sucking a desired volume of the medium through the filter 2 into a filtrate chamber 1 and then creating in the filtrate chamber 1 an overpressure in relation to the flowing medium, whereupon at least part of the material volume of the filtrate chamber can be squeezed out through the filter 2 to the flowing medium to enable solids accumulated on the surface of the filter to be washed away. With the aid of the invention, the cleaning requirement of various pick-ups which are used in on-line analysis of solids-containing liquids can be reduced and, at the same time, the reliability and working life of the pick-ups can be improved. <IMAGE>
