Abstract: The invention relates to an arrangement of a flow measuring device with a testing device. The flow measuring device comprises an inlet section and an outlet section. A rotor is arranged between the inlet section and the outlet section. The rotor is designed for a rotational movement in the event of a fluid flow between the inlet section and the outlet section. At least one indicator element is arranged on the rotor. The flow measuring device further comprises a measuring element, which is adapted to detect a movement of the indicator element. The indicator element comprises a magnetic material. The testing device is designed to set the rotor in rotational motion, preferably without contact. The invention further relates to a method for the functional testing of a flow measuring device.

Abstract: The invention relates to an appliance for the automated preparation of beverages, comprising a dispensing element (1), which comprises a plurality of dispensing openings (2) for dispensing individual beverage ingredients, and also comprising a washing device (3) for dispensing a washing fluid, wherein the washing device (3) is arranged in a retaining region (5) at a location remote from the dispensing element (1), wherein the washing device (3) can be removed from the retaining region (5), and wherein an accommodating region (4), which is designed to accommodate at least part of the washing device (3), is provided on the dispensing element (1), wherein a valve element (2) is provided, said valve element comprising a flushing-fluid inlet (23), an ingredients inlet (24) and a fluid outlet (25), which is connected to at least one dispensing opening (2), wherein the flushing-fluid inlet (23) opens out into a flushing-fluid channel and the ingredients inlet (24) opens out into an ingredients channel, and wherein t
