Pipeline Guardian hardware
Guardian master control panel
- Intelligent panel houses the components to collect, analyze and transmit LDS data
- On-board data storage saves data during long communication outages
- Communications options, TCP/IP, line of sight radio, GSM, satellite uplink
- EXd packing option
- Local processor options for locations with limited comms. The data is processed locally and leak detection results are passed back to the pipeline control center
- All power options – 110-220v line, solar power, or 24v DC
Non-intrusive flow sensors
Non-intrusive flow sensors are less than one tenth of the cost of conventional flow meters and are much easier and cheaper to install (especially for a retrofit). The limited accuracy of non-intrusive flow sensors makes them unsuitable for use with traditional leak detection systems historically. Atmos’s revolutionary software is designed to achieve high sensitivity with inexpensive, non-intrusive flow sensors meters, customized to the Atmos leak detection solution. This lowers equipment costs, installation costs, and maintenance costs while still providing best in class leak detection.
High-resolution pressure sensors: low cost, specially selected for leak detection, to capture even the smallest pressure changes.
Non- intrusive pressure sensor: unique sensors to provide field pressure data to support an effective leak detection without expensive installation costs. No drilling, cutting, or welding required. This sensor can be installed within hours and begins transmitting pressure measurements immediately with zero operational downtime.
Allows acoustic noise correlation to detect a leak by correlating the noise the fluid is making as it escapes the pipeline.
The absence of electric power at remote sites frequently hinders pipeline leak detection. Solar panels specifically designed to power any, or all, of the Pipeline Guardian components in the field. The compact rugged design makes them easy to install anywhere along a pipeline, opening a whole new dimension of hardware-based improvements to pipeline leak detection.
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.
