A method for detecting and controlling cooling system characteristics. A flow rate of make-up cooling medium is measured. A conductivity of the make-up cooling medium is measured. A conductivity of a recirculating cooling medium is measured. A treatment material feed rate is determined based upon the formula: <IMAGE> where X is a treatment feed rate of a treatment compound, OMEGA is a desired concentration of the treatment compound, and K is a constant. A corrosion rate of the recirculating cooling medium is measured. A desired corrosion rate of the recirculating cooling medium is determined. A feed rate of a corrosion inhibitor is calculated according to the following formula:Y=(X)[1+ alpha (CORRMEASURED/CORRSETPOINT)],where alpha is a cascade factor that varies in a step-wise manner depending upon the value of CORRMEASURED/CORRSETPOINT and has a value between about 0.1 and about 8.0. A corrosion inhibitor is then fed at the corrosion inhibitor feed rate. |
