Throughflow measurement device for a beverage preparation machine

The present invention concerns a throughflow measurement device for a beverage preparation machine for measuring the liquid delivered by means of a pump for beverage preparation, comprising a housing (3) which encloses a throughflow pathway, a rotary body (7) which is mounted within the housing (3) and which is driven by liquid delivered through the flow pathway and which has at least one encoder element (10, 10.1), and comprising a receiver unit (19) which is situated outside the housing (3) which encloses the throughflow pathway, said receiver unit being arranged so as to receive the signals from the at least one encoder element (10, 10.1), characterized in that the rotary body (7) has at least one drive body (9) which is arranged with its water-struck side inclined with respect to the longitudinal extent of the axis of rotation of the rotary body (7), and in that the housing (3); which encloses the throughflow pathway of the throughflow measurement device (1) is part of a module which exhibits further functionality, for example a water connection module (2), or of an assembly.
