Leak Detection

What Does Leak Detection Mean?

Leak detection, in context of trenchless technology, refers to the process of using different methods to determine if leaks are present in a pipeline. Pipelines often start deteriorating and leaking with age and should be checked for leaks in order to avoid back flows, blockages, gas leaks or any number of possible scenarios where there is a failure or rupture in the pipeline.


Trenchlesspedia Explains Leak Detection

Two commonly used methods of leak detection, in the context of trenchless construction, are sensor based. One method involves employing an acoustic sensor which is tethered to monitoring equipment on the surface and the other method consists of a free-flowing sensor deployed into the pipe and allowed to travel with the flow of the product within the pipe. The free-flow sensors are used in pipes of all diameters but work well when surveying the larger-diameter mains which often have poor transmission capability, and where access is limited.
