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.
Claims8
An apparatus for dispensing a predetermined volume of fluid comprising:
- (a) a closed-fluid chamber containing the fluid to be dispensed;
- (b) a fill tube communicatively connected to the fluid chamber and forming a closed loop with the fluid chamber;
- (c) a fill valve disposed in the closed circuit formed by the fill tube for controlling the flow of fluid from the fluid chamber into the fill tube;
- (d) sensing means for detecting the level of the fluid in the fill tube;
- and
- (e) a discharge valve for dispensing the contents of the fill tube;
- and
- (f) an electronic controller responsive to said sensing means for selectively opening and closing the fill valve and the discharge valve to first transfer fluid from the fluid chamber to the fill tube and then to dispense a predetermined volume of fluid from the fill tube.
