Abstract: An apparatus and a method for sampling from a product flow, where the sampling is performed continuously and where the product is collected in a cup for determining physical conditions, for example, weight in relation to volume, and where the cup is emptied after ending the sampling. The apparatus is provided with at least one sampling cup provided with a filling opening and an emptying opening with different cross-sectional areas. It is not necessary to perform a turning movement of the sampling cup in order to empty it. Instead, preferably, the sampling cup is emptied by opening/uncovering the bottom. Emptying of the cup and subsequent cleaning of the cup are effected with open bottom by passage of the product flow through the cup; but, emptying may also occur in a separate duct.
