Natural gas leaks are often invisible, difficult to hear, and hard to locate in complex industrial environments. For valve stations, pressure regulating stations, pipelines, and other oil and gas facilities, early leak detection is critical for operational safety, LDAR programs, and methane emission reduction.
During a recent inspection at a PetroChina natural gas valve station, the ATEX-certified HA3LX acoustic methane camera helped identify multiple potential natural gas leak risks. The inspection was performed from a safe distance without direct contact with the equipment, allowing operators to quickly screen valves, flanges, joints, and pipeline connections.
Unlike a traditional methane camera or optical gas imaging camera that mainly visualizes gas plumes, the HA3LX uses acoustic imaging to locate the source of pressure leakage. When pressurized natural gas escapes through a small opening, sealing gap, valve, or connector, it generates ultrasonic signals. In many cases, the ultrasonic energy created by a pressure leak is much stronger than the audible sound. The HA3LX captures these ultrasonic signals and converts them into a visual acoustic image, helping inspectors quickly identify the suspected leak source.
This is especially useful in valve station inspections, where pipelines are dense, equipment is complex, and background noise can make manual inspection difficult. With long-distance acoustic imaging, inspectors can scan a wide area, detect small leaks, and reduce unnecessary close-range checks in hazardous areas.
The HA3LX is also equipped with a methane TDLAS measurement module. Once the acoustic camera identifies a suspected leak point, the methane module can be used to quickly measure methane concentration in the target area. This creates a practical workflow for field inspection:
Detect the leak acoustically.
Locate the source visually.
Measure methane concentration with TDLAS.
Support maintenance decisions with clear field evidence.
For oil and gas operators looking for an OGI camera alternative, a methane leak detection camera, or an ATEX gas leak detection camera, the HA3LX provides a powerful combination of acoustic localization and methane measurement. It helps make invisible leaks visible, improves inspection efficiency, and supports safer LDAR and fugitive emission monitoring programs.
One timely detection can help prevent a potential safety incident.
The ATEX HA3LX methane camera helps operators detect, locate, and verify natural gas leaks faster, safer, and more efficiently.
