Abstract
The liquid transfer system includes a liquid supply tank and at least two pressurizable liquid holding vessels. The liquid holding vessels are placed beneath the supply tank, and a liquid supply line connects the supply tank to each vessel. The liquid supply line is operated as a siphon from the tank to each vessel, in order to move liquid from the tank to each vessel. Each vessel is alternately filled and pressurized to dispense liquid from the vessel, such that one vessel is being filled while the other is dispensing liquid, and a constant controllable liquid output flow is achieved. A preferred embodiment includes a liquid recycling line to recycle or constantly move the liquid within the system to achieve thorough mixing, and an in-line filter to improve liquid purity.
