ABSTRACT:
The invention relates to a filtering device for taking a filtrate sample from liquid matter containing solid particles. The filtering device comprises two filter parts and at least one filtering slot between the filter parts. The filter parts are adapted to move in relation to each other in such a manner that the width of the filtering slot changes when the filter parts move in relation to each other. When taking a sample from a process, the filtering slot between the filter parts is at its smallest, and it is adapted to filter the sample while the liquid matter being measured flows from the process to the measurement. When rinsing the filtering device against the sampling direction, the filter parts are adapted to move away from each other, whereby the filtering slot widens.
