Water level system controls cathodic protection

August 2019 Level Measurement & Control

Corrosion Control Services is a leading specialist in the design, installation, commissioning and monitoring of cathodic protection. CCSL carries out works on reinforced concrete structures, historic and steel-framed buildings, ports and harbours, and immersed pipelines. To help overcome a problem experienced on an existing impressed current cathodic protection system, the company approached Omniflex.

CCSL needed a system that would monitor the level of water in the harbour surrounding the structure and switch the existing cathodic protection (CP) system off if the water level rose too high, and on again when it dropped. In addition, CCSL needed to be kept informed of the status of the system.

The solution

The solution uses a level sensor to measure the water level. If the level gets too high, the mains power supply to the CP system is switched off. When the level drops, the mains supply is switched on.

In addition to the mains supply switching, the system uses an Omniflex Silent Sentry to send SMSs to the appropriate personnel, informing them of the status. The system was installed inside a GRP panel and testing was carried out at Omniflex’s facility prior to shipping to site.

The water level monitoring system was installed close to the existing CP cabinet and routed to the power supply through the new panel. The system now ensures that high water levels do not cause problems with the existing CP system, which in turn protects the residential building above.

CCSL’s Chris Spence, concludes: “Omniflex delivered an excellent product on time and we are extremely satisfied with the solution provided. This was due to the professional approach Omniflex provided from concept through design to installation and commissioning.”
