The Flir GF77a is the first uncooled autonomous leak detection camera from Flir designed specifically to visualize methane gas. This affordable, fixed-camera solution provides upstream and midstream gas processors, producers, or operators the features they need to continuously monitor for potentially dangerous, invisible methane leaks. Small and lightweight, the Flir GF77a is packed with Flir-patented features, such as High Sensitivity Mode (HSM), for improved gas visualization. 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 GF77a also comes in a GF77f variant that includes environmental housing for harsh environments.
An uncooled thermal camera that's spectrally filtered for methane and other industrial gases. This camera provides oil and gas facilities, gas transportation terminals, and power generation plants with continuous, autonomous leak detection. While it's small and lightweight, it is packed with features such as High Sensitivity Mode (HSM), as well as open architecture allowing third-party analytic solution integration for visual confirmation of leak.
The camera can help companies throughout the oil and gas industry better maintain valuable capital equipment, avoid product loss, meet emissions reduction metrics, and ensure safer work practices.
Dependable fixed OGI solution
Uncooled camera offers many industry-leading features for continuous monitoring applications.
- Increase leak detectability by activating High Sensitivity Mode (HSM)
- Remote motorized focus ensures a crisp image and measurement accuracy for objects at different distances
- See more with dual-streaming capabilities from thermal plus built-in digital cameras
- Simple third-party integration thanks to open architecture
Designed to visualize industrial gases
Spectrally-filtered to detect gases, improving worker safety and leak location identification.
- Continuously monitor for methane emissions so you can begin repairs immediately
- Visualize gases in specified spectrum while also reducing false negatives of gases that absorb in another wavelength
- Temperature-calibrated for added use in thermography, fire detection, and worker safety
- Install multiple units across a facility to maximize leak detection with fewer in-person inspections
Advanced features for unmatched connectivity
State-of-the-art technology allows simple integration to meet existing industrial needs.
- Connects to a network for continuous, autonomous leak detection
- RTSP and GigE compliant for flexibility to meet many industrial communication needs
- ONVIF compliant to ease integration with standard security and NVR solutions
- Compressed radiometric image streaming saves network bandwidth and allow multiple outputs simultaneously
