Our inline corrosion rate monitoring utilized the linear polarization resistance (LPR) method to produce a raw signal that is conditioned, amplified and digitized directly in the sensor itself. It is a valuable tool that can be easily and affordably deployed to provide both general and localized corrosion measurements quickly. Using an inline LPR corrosion sensor differs from using corrosion coupons, because the LPR corrosion level represents the real-time electrochemical measurement of corrosion on an MPY scale based on the assessed metallurgy, whereas corrosions coupons cannot provide such real-time measurements. The LPR corrosion rate sensor is ideal for cooling and process water treatment monitoring where robustness and affordability are a must. The LPR corrosion sensors measure sample water conductivity directly and compensate for the conductivity impact on LPR measurement, these unique product characteristics make the LPR superior in performance and accuracy. In addition to the LPR measurement used to obtain the general corrosion rate, the sensor also measures for electrochemical noise, the measured noise data being used to calculate an index to quantify the localized corrosion rate commonly referred to as pitting.
