Abstract:
A system for mixing a first liquid chemical with a second liquid chemical, comprising:a main reservoir associated with a first liquid chemical valve, a second liquid chemical valve, a liquid chemical output valve, a gas input valve, a load cell generating a first signal indicating the amount of first liquid chemical in the main reservoir and generating a second signal indicating the amount of the second liquid chemical in the main reservoir, and a mixer assembly; and a controller, coupled to the load cell, the first liquid chemical valve, the second liquid chemical valve, the liquid chemical output valve, and the gas input valve, wherein the controller actuates the first liquid chemical valve to supply the first liquid chemical to the main reservoir in accordance with the first signal, the second liquid chemical valve to supply the second liquid chemical to the main reservoir in accordance with the second signal, the gas input valve to supply pressurized gas to the main reservoir, the mixer assembly to mix the first liquid chemical and/or the second liquid chemical, and the liquid chemical output valve to deliver the liquid chemical(s) resulting from the first and second liquid chemicals mixing in the main reservoir.
