Abstract:
1. A system for monitoring and controlling corrosion in a hot water system, comprising: an oxidation-reduction potential probe capable of measuring a reduction potential of the hot water system substantially in real time; a controller unit operatively coupled to the oxidation-reduction potential probe, wherein the controller unit activates a feed of at least one water treatment chemical in response to the measured reduction potential so as to maintain a pH within a predetermined range; and at least one inert tracer molecule for measuring a concentration of a pH altering species, and wherein the controller unit activates the feed of the water treatment chemicals in response to the measured concentration of the pH altering species so as to maintain the pH within the predetermined range at the measured concentration of the pH altering species and sodium to pH altering species ratio.
