Abstract

A fluid dispensing apparatus is configured to dispense a predetermined volume of fluid, and includes a fluid reservoir to hold a fluid to be dispensed, a dispense tube to dispense the fluid, and an elevator mechanism. The fluid reservoir receives a fluid from a fluid supply. A dispense tube has a dispense outlet, and is connected to an outlet port on the fluid reservoir. The elevator mechanism changes a relative vertical displacement between the dispense outlet and the outlet port. Particularly, a processor controls the elevator mechanism to raise the dispense tube to a raised filling position to prevent fluid flow from the dispense outlet, and lower the dispense tube to a lowered dispensing position to dispense the fluid.
