Abstract
A corrosion monitoring device for monitoring corrosion in fluid containing systems and other equipment exposed to a corrosive environment comprising sensor elements having a composition substantially the same as the equipment being monitored, the sensor elements having a predetermined thickness for exposure to a corrosive solution of the fluid containing system. An electrical property of the monitoring device changes when corrosion penetrates through the thickness of the sensor element. A digital output device generates a first binary signal when corrosion has not penetrated through the thickness of the sensor elements, and a second binary signal when corrosion has penetrated through the thickness of the sensor elements. Multiple sensor elements may be used to provide multiple binary signals. Information from the digital outputs may be processed to provide a cumulative log of corrosion measurements.
