Automated solution making

A method for automatically producing a solution, the method comprising:

• depositing a chemical in a hopper;
• adding a solvent to the hopper, wherein the chemical at least partially dissolves in the solvent to form a solution;
• measuring a conductivity of the solution external to the hopper and correlating the conductivity of the solution to a concentration to establish a concentration of the solution;
• comparing the concentration of the solution to a target concentration;
• automatically diluting the solution if the solution is over-concentrated;
• automatically increasing the concentration of the solution if the solution is under-concentrated by returning the solution to the hopper;
• automatically diverting the solution to a storage tank if the solution concentration is within tolerance of the target concentration;
• and
• automatically flushing a deposit of foreign material from the hopper.
