The invention relates to a method and device for taking samples for analysis from slurry flows containing solids, in which method a two-step sampling is applied; in the first step, there is applied primary sampling, and in the second step, secondary sampling. According to the invention, the speed of the flow entering the primary sampler (2) is essentially equal to the speed of the process flow (1), but higher than the speed of the flow in the surroundings of the secondary sampler (5).

La présente invention concerne un procédé et un dispositif pour prélever des échantillons en vue de l'analyse d'écoulement de bouillie contenant des solides. Ce procédé consiste à effectuer un prélévement en deux étapes. Au cours de la première étape, on effectue un prélèvement primaire, et la deuxième étape comprend un prélèvement secondaire. Selon l'invention, la vitesse de l'écoulement pénétrant dans l'échantillonneur primaire (2) est sensiblement égale à la vitesse du flux de production (1) mais est supérieure à celle de l'écoulement dans l'environnement de l'échantillonneur secondaire (5).
