An advanced development of the original ER ratiometric method, the technique measures changes in current density due to material loss. When applied to a Sample and Reference array in the form of a probe or sensor the instrumentation provides a signal-conditioned, calibrated output. The principal parameters of interest are metal loss and process temperature but advanced applications may include others related to localised effects and conductivity due to surface defects, inclusions, conductive deposits or solutions in contact with the electrically conductive path through the metallic sample. In CEION®, precision electronics, inherent noise rejection and configurable, embedded, real-time compensation algorithms combine with sensors designed for micro-structural, thermodynamic and hydrostatic balance to deliver exceptional performance. Corrosion & Pitting Monitors Sand Erosion Monitors Pipeline Flow Assurance Chemical Optimisation First introduced in 1999 the technology has been used to power a wide range of devices including, corrosion probes, sand erosion detectors and pipeline corrosion monitors. Applications on surface and subsea installations, refineries, petrochemical plants and in the laboratory are in service world-wide; including the Gulf of Mexico, West Africa, UK and Norwegian Continental Shelf, Australia, Middle East, North Africa, Latin America and Asia. We are continuously developing new applications for the technology, often sponsored by end-users, targeted at solving specific industry problems.

This is a level commonly found in carbon steel hydrocarbon systems under normal operating conditions. Higher metal loss rates mean faster responses but it is important to measure quickly and accurately at normal operating metal loss rates so that process changes are detected immediately. *may be caused...
