Abstract
A device for automatic dilution of chemical additives and water utilizing a single pump (20) drawing water and other chemical additives through a dilution manifold (24). The chemicals are fed through adjustable orifices and valves, and a microprocessor based controller oversees and controls system operation. Two digital flow meters are arranged wherein the controller compares the difference between the flow meters and delivers a desired volume of the chemical additive and water.
