| 摘要 |
The invention relates to a method and apparatus for taking slurry samples containing solids from a large, essentially horizontally flowing process flow, in which process flow there is at least partly immersed a sampler, and where the sampling is carried out in at least two steps. According to the invention, in the first sampling step, the solids-bearing process flow 3 is conducted into a sampler 2 comprising at least three sampling units 1 that are arranged in the process flow channel in such a position that in the process flow direction 4, at the same spot where part of the process flow enters the sampling units 1, the slurry flow left outside the sampling units 1 is directed onto a lower level 6. In addition, the slurry flows obtained from the sampling units 1 are combined and subjected to mixing before the slurry flows are returned to new sampling that alternatively includes either the first sampling step 13 or the extracting of a sample for a analysis.
