MICROCOR® SYSTEMS The Microcor corrosion monitoring technology has been developed to substantially increase the speed of response over conventional monitoring techniques, such as coupons, electrical resistance (ER) probes, and linear polarization resistance (LPR), and is functional in all environments. 10000 M4700 Probe in COSASCO® Fitting Response Time (hrs) based on 50 units of resolution for Microcor, 10 units for Corrosometer Increased Speed of Response of Microcor Systems The Microcor measurement is based fundamentally on metal loss and is therefore directly comparable to ER probe data and coupon data. It does not depend on the empirically determined electrochemical constants of LPR measurements, or the complex and variable analysis of electrochemical noise techniques, both of which require an electrically conductive solution for accurate measurements. Microcor Transmitter and Retractable Probe in Field Installation Microcor is the result of patented technology which combines the rapid response of LPR and the universal applicability of ER. The figure below compares the real world response of various corrosion monitoring methods to the Microcor system. Corrosion rate on a logarithmic scale is plotted against time, also on a logarithmic scale. At 10 mpy, the common W40 electrical resistance probe takes nearly 3 days to show a clear response. A Microcor probe with the same useful probe life will show a clear response in 1 hour, and the trend is visible in 15 minutes. Even an LPR probe in water will take 5 to 10 minutes to produce a steady corrosion rate reading. This means that the Microcor system is 50 to 100 times more sensitive and faster in response than ER systems. The absolute resolution of the Microcor electronics is 256 times more sensitive than ER system electronics. The active element of a Microcor probe is measured to an 18 bit resolution, or 262,144 probe life units. This compares to the 10 bit resolution (1000 divisions) of an ER system. As a result of the proprietary design of the probe and the electronics, the Microcor measurement system is much less sensitive to fluctuations in temperature. The Microcor probes are available in two element forms, flush and cylindrical. Flush probes are suited for pipelines, where pigging may occur, and for bottomof-line monitoring in oil and gas, or multi-phase flows where typically the corrosive water phase exists. Cylindrical probes with their all-welded construction are suited for more chemically aggressive environments.

Two software package options are available. The first option is ICMS3 software that provides complete corrosion management, where corrosion rate data can be plotted in real time in parallel with related process variables such as temperature, pressure, pH, dissolved oxygen, inhibitor concentrations etc. M4700 Flush and M4500 Cylindrical Probes The second option for smaller scale systems is the low cost Microcor Tools Software, which is also available for continuous on-line operation, or for gathering of data from the Microcor data-logging system. Therefore, Microcor offers, for the first...
