1. A system for mixing a liquid and a powder into a solution batch comprising:
a hopper into which said powder is deposited having a powder outlet therein and a powder control valve in fluid communication with said powder outlet;
a mix tank having a liquid supply inlet in fluid communication with a liquid inlet valve, a recirculation inlet in fluid communication with said liquid inlet valve, and a solution outlet;
a mix pump in fluid communication with said solution outlet, said powder outlet, and said recirculation inlet;
a controller having a data memory and a plurality of inputs and outputs for supplying and receiving signals, and an operator interface operatively coupled to said controller for receiving user commands; and
a pressure sensor disposed in fluid communication with said mix tank for monitoring the pressure of the solution in said mix tank, said pressure sensor having an output operatively coupled to an input of said controller, whereby said controller provides an indication of solution concentration through said operator interface.
