Acquiring and Analyzing Electrical Resistance Probe Data Using Web-Based Remote Monitoring Tools

Corrosion rate monitoring techniques, using coupons and probes of various designs and technologies, have been in use for decades in some form or another. Weight-loss coupons were an early type of direct measurement of metal loss to determine the rate of corrosion in many applications, internal and external. These coupons could be placed where corrosion is suspected to be occurring and the rate of corrosion determined by removing and weighing the coupon after a set period.

This paper explores the use of remote monitoring systems and web-based data analysis to track corrosion rates in real time. Combining monitoring systems with electrical resistance (ER) or linear polarization resistance (LPR) corrosion probes allows measurement of corrosion rate more frequently.


Real time transmission of the field data at more frequent intervals provides a greater number of data measurements. Increased data density enables faster and more accurate evaluation of corrosion rate trends. Interactive, web-based analysis provides the user with a tool that allows tracking of corrosion rates in real time. Additionally, corrosion rate changes can be easily isolated to evaluate the effects of environmental or mitigative factors.


Corrosion probe measurements are affected by many factors, including temperature, sensitivity, environmental changes, etc. Individual measurements may appear inconsistent. Typically, a number of historic measurements are averaged to produce a trend. Data analysis tools provide the user with realtime data trending capability. Interactive graphic data analysis enables the user to view the corrosion rate using a variable number of historic measurements to include in creating a rolling average corrosion rate. The user may also view and compare corrosion rates between any two points in history and view cumulative metal loss to evaluate probe life consumption. Relevant applications include monitoring corrosion rates in soils, tanks, casings, pipelines, atmospheric environments, solutions, and offshore immersed structures.
