Title: Low Cost Cathodic Protection Potential Readings

Abstract: The development of a simple digital meter allows meter readers to obtain accurate corrosion readings. This paper describes the evolution of this concept and its implementation. The system allows meter readers to obtain most of the annual corrosion readings for a very nominal cost. Cathodic Protection has been recognized for many years as an effective means of halting corrosion on underground metal gas distribution piping. As early as 1945, NI-Gas was involved in a program to install anodes and other materials to protect its transmission and distribution systems. Even at that time, it was known that if the piping was kept at a -.85 volts or more, there would not be any corrosion.
