Abstract:
1. A system for formulating a chemical solution by combining water with a plurality of component chemical concentrates, the system comprising: a first storage tank that stores a first component chemical concentrate; a second storage tank that stores a second component chemical concentrate; an output port that receives the water from a water source, the first component chemical concentrate from the first storage tank and the second component chemical concentrate from the second storage tank, wherein the output port dispenses the water, the first component chemical concentrate and the second component chemical concentrate to a solution container to form the chemical solution therein; a flow meter that measures volumetric readings representing a volume of the water communicated between the water source and the output port; a first weight measuring device that measures weight readings representing an actual weight of the first component chemical concentrate contained in the first storage tank; a second weight measuring device that measures weight readings representing an actual weight of the second component chemical concentrate contained in the second storage tank; and a controller operable to control supply of the water, the first component chemical concentrate and the second component chemical concentrate to the output port based on the volumetric readings and the weight readings to form a specified amount of the chemical solution in the solution container.
