Atmos Wave detects the rarefaction wave caused by a leak in a pipeline. When a leak occurs, a rarefaction wave travels in both directions along a pipeline. Using fast response pressure meters Atmos Wave filters the pressure signals to find those with the frequency and magnitude of a leak. The time at which the pressure signal reaches each pressure meter is used to determine the location of the leak extremely accurately. Atmos Wave is the result of several years of research and development directed at producing a pressure-based leak detection system that is capable of differentiating between pressure waves that originate from pinhole leaks and the background noise and other pressure signals caused by normal pipeline operations. Extensive performance evaluation and field trials have proven that Atmos Wave can detect small leaks without generating false alarms due to pipeline transients or process noise.
Features Include:
· Very low false alarm rate
· Based on high performance, off the shelf pressure meters from reputable manufacturers
· Detection of leaks less than 1% of nominal flow-rate within 4 minutes, resulting in a very small product release before a confirmed leak alarm
· Detection of existing pinhole leaks, under running or shut-in conditions
· Location of leaks within ± 100 to ± 400 metres depending on operational conditions during the leak
· Dedicated data acquisition unit (AWAS) certified to the European Union's ATEX Zone 1 standard, with local data storage to mitigate the effect of communication failures
· Detection of pipeline thefts effectively including the closure of a theft valve, which is very useful for identifying theft locations
Sensors Used:
- Primary sensors are pressure sensors positioned 0.3km – 240km apart
- Flow and pressure can serve as secondary inputs for full section coverage (i.e., no blind zones close to the pipeline ends)
- Detects when thieves open or close the theft valve on an illegal tapping point
- Accurately locates the theft or leak
- Easy to retrofit
- Detects leaks during steady-state, transient and shut-in conditions
- Leak alarm
- Leak location
- Leak rate and volume lost
- Leak time
- Watchdogs via OPC
