Merlin - Model RMU - Remote Cathodic Protection Monitoring System
Remotely Monitors Cathodic Protection Levels at Rectifiers and Test Points Along Pipelines.Abriox has developed the MERLIN system with input from pipeline operating companies and independent CP consultants. The MERLIN system remotely monitors cathodic protection levels at rectifiers and test points along pipelines, and also the pressure within nitrogen sleeves.
All measured data is automatically transmitted in a management report to the system HQ where it is displayed and archived in Abriox’s CPSM software or online via iCPSM. The system is proactive - identifying potential corrosion problems wherever and whenever they occur and alerting the operator immediately.
MERLIN Remote Cathodic Protection Monitors (also known as Remote Monitoring Units - RMUs) are commonly used at:
- Rectifiers and Solar Stations - measuring electrical supply, voltage output, current output, ON and OFF potentials and also interrupting the current output for above ground surveys
- Test Stations, CP Posts and Riser Posts – measuring pipe to soil ON potentials, instant OFF potentials, coupon currents
- On-shore Tanks, Sacrificial Anodes, Isolation Joints and Critical Bonds
- Pipeline Sleeves - measuring nitrogen/inert gas levels
