Rotary beverage receptacle-filling apparatus for transparent receptacles has a plurality of receptacle sites spaced apart at its periphery with filling components with electrically driven controls controlling the flow of beverage. Stationary video cameras next to the apparatus measure the filling level in the receptacles near a level limit and to produce closing signals to the flow controls of those receptacle sites at which a receptacle reaches a limit level leading to the desired nominal level, if necessary taking into account any post-flow. One video camera covering several receptacle sites is provided as the measuring device and is connected to an image analyzer driving all controls. The analyzer continuously monitors the observed receptacles while also ascertaining the angular positions of receptacle sites associated with them, measuring the particular filling level reached in several angular positions and, when the limit level is reached in a receptacle, transmitting the closing signal to the control of the associated receptacle site.
