A measuring system automatically determines and/or monitors quality of a dairy product. The measuring system includes a housing for a container containing the dairy product, a viscosity measuring device, and a control unit. The viscosity measuring device includes a magnetic first body, an electromagnetic drive, and a detection system that detects displacement of the magnetic first body. The electromagnetic drive includes a plurality of individually controllable coils in a stack. The control unit is configured to individually energize the coils in a predetermined pattern in such a way that the magnetic first body is displaced. The magnetic first body is able to be readily pulled up, even in viscous liquids, but can also be pulled down in a controlled manner so that the viscosity can be measured more accurately.
