Abstract

A fluid dispensing apparatus includes a fluid chamber and a fill tube which forms a closed loop with the fluid chamber. A pair of level sensors are disposed adjacent to the fill tube. Fluid is directed from the fluid chamber into the fill tube through a fill valve. When the fluid level in the fill tube rises to a first predetermined level, the fill valve is closed and a discharge valve is opened to dispense the contents of the fill tube into a container. When the level of the fluid in the fill tube drops to a second predetermined level, the discharge valve is closed and the cycle is repeated.
