ABSTRACT:
A liquid dispenser system for moving a measure of liquid through a conduit from a source container to a receiving container. A branched flow path is defined between a source of pressurized fluid via a first branch sealingly coupled to the source container and a second branch leading communicatively to said conduit at a location between the intake end and the delivery end. A valve is provided to direct the pressurized fluid along one of said first and second branches. A through coil is interposed between said second branch and said conduit. The first branch terminates above the liquid level of the source container. Pressurized fluid is first directed along said first branch causing liquid flow toward the delivery end of said conduit. When flow of the leading liquid is detected, pressurized fluid is directed to the said location along the second branch to split the flowing column of liquid to deliver the portion above the split to the receiving container and the rest back to the source container.
