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
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.
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)
