Operator installs Atmos Pipeline Guardian Leak Detection System
Following extensive testing of the Atmos Guardian Wave Flow System, the pipeline company is now installing the pipeline Guardian hardware and software on multiple underground pipelines. The pipelines transport a range of refined products, from a terminal to a tank farm 5 kilometers away. The main requirement for this system was leak location accuracy and sensitivity, as the aging pipeline runs beneath a high consequence area where communities live. Concerned with the risk of corrosion causing a leak, the conscientious operators required a system capable of locating leaks with sufficient accuracy to minimize the be excavated to make repairs. This is important as pipeline operator would potentially need to dig beneath people’s homes to expose the pipeline.
An extensive leak trial included several controlled product withdrawals to test the sensitivity and leak location ability of the Atmos Guardian Wave Flow System. The LDS system detected leaks less than 1% of nominal flow during static (no flowing) conditions with a location accuracy as good as 12m and detected leaks less than 1% of nominal flow during dynamic (flowing) conditions with a location accuracy as good as 81m.

Atmos is providing a full turnkey solution, including ultrasonic flow meters, pressure sensors and a master-control panel containing the components to collect, analyse and transmit the LDS data. This pipeline had not been designed for a leak detection system (LDS).
Atmos Pipeline Guardian provides a complete range of advanced LDS hardware and software to overcome traditional LDS limitations, such as uncertainties of conventional pipeline instrumentation, lack of instrumentation in the right locations, and lack of infrastructures such as power and communications.
Pipeline Guardian can add a powerful, extra dimension to any pipeline company’s Leak Detection Program through the ability to easily install effective leak detection systems on pipelines where solutions were previously very difficult or even impossible to implement.
