ABSTRACT:
There is provided an apparatus for taking a sample-flow from a main suspension flow, said apparatus having a first chamber which is adapted to receive said main suspension flow and which communicates with a second chamber via weir means. The second chamber has at the lower portion thereof first and second opening means for dividing the suspension received from the first chamber into a sample-flow and a main residual flow, said first and second opening means communicating with a respective means for exerting on the suspension in the second chamber a counterpressure of such magnitude that the level of suspension therein is substantially the same as the level of suspension in the first chamber and that the speed at which the suspension flows into the first opening means is substantially equal to the speed at which the suspension flows into the second opening means.
