Abstract
A liquid transfer system for transferring liquid from a plurality of containers to a plurality of destinations comprises a plurality of inlet valves. Each inlet valve is operable between an open position allowing liquid from a container to be drawn into the system and a closed position blocking liquid from a container from being drawn into the system. Liquid drawn from each of the liquid containers is delivered to a buffer chamber designed to degas the liquid in the buffer chamber. The buffer chamber leads to a vented feeder chamber that is also adapted to retain a volume of liquid. A chamber connection valve is provided between the buffer chamber and the feeder chamber to allow or block the flow of liquid between the buffer chamber and the feeder chamber. The feeder chamber is connected to a plurality of distribution valves operable to deliver liquid to a plurality of destinations.
