Abstract
Techniques for dispensing a type of liquid in a specific amount or at a constant flow rate are disclosed. According to one aspect of the present invention, a height difference between an inlet and an outlet is maintained by an adjustable tubing assembly. An overflow assembly is provided to divert any overflow of the liquid from entering a reservoir and keep a specific level of the liquid. A valve is provided to the inlet and can be turned off when a sensor detects that there is an overflow of the liquid in the overflow assembly.
