ABSTRACT:
A polymer processing system has a polymer input and an electrolyte input which may be varied independently of each other. The polymer and electrolyte are combined and mixed to provide an out flowing solution which flows through a sensor cell that gives an output signal indicating the concentration of polymer in the solution leaving the processing system. The user repeatedly and incrementally sets the inflows of polymer and electrolyte to provide a preselected variety of concentrations of polymer in the out flowing solution. On each incremental setting, a memory stores information relating the concentration to the output signal. Thereafter, the processing system automatically maintains any desired polymer concentration in joint response to the output signal and the stored information.
