Abstract:
1. A system comprising: a storage tank that stores at least one component chemical concentrate; a controller that receives an instruction requesting formulation of a specified amount of a chemical solution and determines a target volume of water and a target weight of the at least one component chemical concentrate based on the specified amount of the chemical solution; an output port that receives water from a water source and the at least one component chemical concentrate from the storage tank and dispenses the water and the at least one component chemical concentrate to a solution container; a flow meter that measures volumetric readings representing a volume of the water supplied from the water source to the output port; and a weight measuring device that measures weight readings representing an actual weight of the at least one component chemical concentrate contained in the storage tank, wherein the controller further controls supply of the water to the output port based on the volumetric readings and controls supply of the at least one component chemical concentrate to the output port based on the weight readings to form the specified amount of the chemical solution.
