In industrial environments where volatile substances are handled, early detection of gas leaks is essential to ensure human safety, protect the environment, and prevent economic losses. FLIR optical gas sensing (OGI) cameras represent a high-tech solution for quickly identifying leaks invisible to the naked eye.
What is an OGI camera and how does it work?
FLIR Optical Gas Imaging (OGI) cameras are designed to visualize gases that are invisible to the human eye. They do this by using specialized infrared sensors to measure the infrared radiation that passes through a volume of gas.
Each gas has a unique optical “fingerprint,” meaning it absorbs infrared light in specific ranges of the spectrum. OGI cameras take advantage of this characteristic by using spectral filters tailored to those ranges to “see” the gases. Thus, when a leak is occurring, the gas is displayed on the camera as a moving cloud against the background, allowing leaks to be detected even remotely and in real time.
This technology not only enables non-contact detection but also enables safe inspections from a safe distance, even in difficult-to-reach or hazardous areas.
Advantages of FLIR Cameras for Gas Detection
Fast and Accurate Detection: They allow for instant leak detection, speeding up maintenance and mitigation processes.
Increased Operational Safety: By detecting leaks without direct exposure, the risk to technical personnel is reduced.
Regulatory Compliance: They help comply with environmental and safety regulations such as the U.S. EPA, LDAR (Leak Detection and Repair), and others.
Cost Savings: Minimizing losses from undetected leaks translates into significant long-term savings.
Visual Documentation: Captured images and videos serve as technical evidence and audit support.
Featured FLIR OGI Camera Models
FLIR has a specialized line of cameras for different types of gases and operating conditions. Some of the most commonly used models include:
FLIR G620a: High resolution and accuracy. Designed for remote leak detection and detailed analysis in complex processes.
FLIR GF77a: More affordable and versatile. Detects gases such as SF₆, ammonia, and other industrial gases.
Each of these models offers recording capabilities, connectivity, and compatibility with analysis software to facilitate reporting and predictive maintenance.
Common Industrial Applications
FLIR OGI cameras are widely used in critical industries, including:
- Oil and Gas: Monitoring distribution lines, valves, compressor stations, and tanks.
- Chemical and Petrochemical: Process inspection, leak detection in reactors and pipelines.
- Power Generation: Verification of refrigeration systems with SF₆ and other gases.
- Environment: Monitoring fugitive emissions and complying with environmental regulations.
