At a time when operators are facing continued production challenges from sand and corrosion and all too often a lack of integration across their asset integrity management systems, the new Roxar CorrLog & SandLog Wireless transmitters will provide flexible, cost effective and accurate online monitoring of sand and corrosion, extending equipment life and increasing production from reservoirs.

Key benefits of the Roxar CorrLog & SandLog Wireless transmitters include:

• Flexible & Cost Effective. The wireless transmitters will result in a significant reduction in installation costs compared to wired online systems and will also allow for monitoring in previously inaccessible areas. Furthermore, a 20 meter probe cable between probes and transmitters ensures increased flexibility, optimum positioning, and easy maintenance.

• Increased Accuracy & Reliability with a low risk of  signal loss in high risk applications, better data & trending, and highly sensitive sensors generating improved information for asset integrity protection.  All probe functions (Electrical Resistance (ER), Linear Polarization Resistance (LPR) and Galvanic) are integrated within the Roxar CorrLog transmitter and multi-element sand/erosion probes are incorporated within the Roxar SandLog transmitter to provide increased accuracy.

• Seamless Integration. Rather than a collection of ad hoc monitoring instruments, the Roxar CorrLog & SandLog Wireless transmitters are one element of a complete asset management system with direct integration through the Emerson Gateway to Emerson’s Smart Wireless system, PlantWeb™ as well as access to Roxar Fieldwatch, Emerson’s windows-based field monitoring system for advanced data analysis. Probes can be read from other manufacturers and the direct transmission of metal loss values, for example, can be fed into Fieldwatch for improved monitoring and analysis.

The CorrLog and SandLog Wireless Transmitter systems are based on intrusive sensors that are installed into pipes or vessels through an access fittings system. Access systems are divided into low pressure systems, such as retractable probes often used in refineries or chemical plants, and high pressure systems, where the Roxar ROV Retrieval System is recommended. The Roxar CorrLog & SandLog wireless transmitters are certified by ATEX and other bodies.

The operating principles of the sand probe are based on the Electrical Resistance (ER) corrosion probe technique which relies on the erosive effects of sand particles on thin non-corrosive elements mounted on a probe inserted into the pipe. The Roxar CorrLog Wireless corrosion transmitter is based on the proven, highly accurate and field reliable CorrLog instrument.
