Claim Text:
1. A method for determining the amount of corrosion which has occurred on an interior surface of a process unit due to a corrosive fluid comprising: (a) providing a corrosion sensor that is located within the process unit; wherein the corrosion sensor is a metal loss sensor, an electrical resistance sensor, or a linear polarization sensor; (b) exposing the corrosion sensor to a corrosive fluid within the process unit; (c) determining the corrosion that has occurred on the corrosion sensor, and (d) relating the corrosion of the corrosion sensor to the amount of corrosion which has occurred on at least one point on a surface of the process unit; wherein the at least one point on a surface of the process unit is at a point other than where the corrosion sensor is located and wherein the at least one point on a surface of the process unit is an interior wall of a pressure containment boundary; wherein the relating of the corrosion on the corrosion sensor to the corrosion on the process unit comprises;
