Find gas leaks while meeting governmental and environmental emission goals with the FLIR G620a: a long-lived, cooled OGI camera solution for continuous monitoring at upstream and midstream gas production and processing facilities.
The G620a is spectrally filtered to see methane (CHâ‚„), hydrocarbons, and Volatile Organic Compounds (VOCs) with a performance OGI detector that meets sensitivity requirements set forth in U.S. EPA OOOOa and Appendix K. Small and lightweight, the G620a installs quickly and relies on a simplified web interface. Never miss a moment of real-time monitoring, thanks to the robust cryogenic cooler which supports 27,000 hours of non-stop operation. The high-resolution, high sensitivity cooled midwave infrared (MWIR) sensor plus FLIR’s proprietary High Sensitivity Mode (HSM) allows users to visualize even the smallest gas leaks. Connect and run cameras easily through included web interface, available software development kits (SDKs), and industry-standard GigE vision protocol. The GF77a can help oil and gas companies maintain valuable capital equipment, avoid product loss, meet emissions reduction metrics, and ensure safer work practices.
The Gx620f version is certified for use in hazardous areas (ATEX, IECEx, ETL) and is ONVIF compliant to integrate seamlessly with plant monitoring systems. The hazardous area certified Gx620pt pan-tilt version provides 360° continuous pan and wide tilt range to enable full-site coverage from a single mounting point.
The FLIR G620a can help oil and gas companies maintain valuable capital equipment, avoid product loss, meet emissions reduction metrics, and ensure safer work practices. Â
