Abstract

The invention pertains to an arrangement and a method for the automatic sampling in a storage tank system (1) interconnected to a pipe system (4) for supplying cleaning fluids, particularly in processing systems that are subject to high microbiological quality requirements in the food and beverage industry, particularly in breweries, with a storage tank system (1) that consists of several tanks and a sampling device (5) that is respectively associated with all tanks via permanent pipework. The invention ensures that the entire sampling system including all valves integrated therein can be cleaned and sterilized in a flow-through fashion regardless of the respective content of the tanks. Furthermore, the sampling should take place without a loss of the fluid to be sampled. This is procedurally achieved in that a volume flow Q(P) of the fluid (P) to be sampled is diverted from a selected tank (1.i), wherein this volume flow Q(P) is fed to the sampling device (5) and is returned from the sampling device into the selected tank (1.i), and wherein a quality control of the fluid (P) to be sampled is carried out in a flow-through fashion and/or a sample quantity (PR) of the fluid (P) is diverted from the volume flow Q(P) within the sampling device (5) during the circulation of the volume flow Q(P).
