  • Patent number: 5427161
    Abstract: Rotating beverage receptacle-filling equipment for filling receptacles has receptacle sites spaced along its periphery and metering containers which can be filled from a beverage tank. Beverage is discharged from the metering containers into the beverage receptacles. A control system recognizes upper and lower liquid levels in the metering containers to control the discharge volume. The metering containers are transparent and at least one stationary video camera observes the metering containers of several adjacent receptacle sites. An image analyzer continuously monitors the metering containers in the field of view of the camera while detecting the levels in different angular positions at the receptacle sites and generates control signals for valves at the receptacle sites. A camera observes the refill limit level to control a refill valve and a camera observes the discharge limit level to control a discharge valve.
