PCT No. PCT/SE79/00242 Sec. 371 Date Aug. 4, 1980 Sec. 102(e) Date Jul. 1, 1980 PCT Filed Nov. 30, 1979 PCT Pub. No. WO80/01205 PCT Pub. Date Jun. 12, 1980.A device for taking from a flowing suspension a sample-flow representative of said suspension comprises a first chamber (18) arranged to receive the flowing suspension, said first chamber communicating via a weir (23) with the upper part of a second chamber (22) having first and second openings (25, 26) arranged at the bottom thereof for removing the sample-flow and the remaining part of said suspension respectively. The openings, (25, 26) are separated from each other by partition walls (27) which extend transversely of the weir over the whole length of the second chamber and communicate with a respective outlet (15, 20; 21). The openings (26) for receiving the said remaining part of the suspension communicate with the associated outlet (21) via a substantially U-shaped passage and a second weir (29) which is located substantially on the same level as the weir (23) of the first chamber. In order to prevent blockage of the U-shaped passage while maintaining requisite precision of the device, at least one of said partition walls (27) exhibits means for maintaining communication between said U-shaped passage and the sample-flow outlet (15, 20) in a region located beneath the uppermost level (33) of the connection (30) between the two legs of the U-shaped passage.
