Abstract

The invention relates to a sampling method and filter for taking a liquid sample from a suspension containing liquid and solid matter by filtering. The filter has a rotatable filtering element (1), filtering means (6, 5, 8, 9) not rotating in relation to the filtering element for the continuous filtering of the liquid through the filtering element and cleaning means (11, 10, 13, 14) not rotating in relation to the filtering element for the continuous cleaning of the filtering element. The invention is especially suitable to be used in the process industry and in such applications in which only a small amount of the sample is needed.
