Pipeline Guardian software

Intelligent flow balance (Wave Flow)

The mass, volume, or flow balance element of Atmos Wave Flow corrects both measurement errors and inventory.

Negative pressure wave

Uses comprehensive algorithms to filter process noise and interference from pressure data associated with the rarefaction wave, caused by the onset of a leak, into a detailed 3-dimensional map. This map allows the system to clearly differentiate true leak/theft events from the pressure changes caused by transient operation. The result is a more responsive system with reduced uncertainty.

Dynamic model analysis (pressure/flow rate modeling)

A leak changes the pipeline flow and pressures in a distinctive pattern. The dynamic model analysis module analyses the pressure and flow behaviors, and can achieve a leak sensitivity better than the accuracy of the flow meters.

  • Leak onset detection

  • Fast leak detection

  • Improved sensitivity

Acoustic noise correlation

A small pipeline leak creates a white noise sound that travels through the fluid to the high performance Atmos acoustic sensors, placed upstream and downstream of the monitored section.

  • Detects existing leaks

  • Detects corrosion leaks as they open

  • Provides accurate leak location

Main features

  • Response time in minutes for shut in, transient, and steady state conditions

  • Sensitivity <1% of flow rate

  • Minimal product release before a confirmed alarm

  • High leak location accuracy

  • Detects slowly developing leaks (corrosion leak detection)

  • Leak detection and location

  • High performance, proven pressure sensors and flow meters

  • Non-intrusive sensor options available

  • On-board data storage to mitigate the effects of communication failures

  • Not reliant on flow meter’s performance or calibrations

  • RTTM for inventory (line pack) and integrated hydraulic profile

  • Turnkey packaging and sensor options

  • Complies with API 1130 (R 2012) and API 1175

Pipelines with column separation

Guardian hardware can be placed to optimize leak detection in slack pipeline sections as well as filled pipeline sections.
