Camera offers high-sensitivity gas-leak visualisation

FLIR Systems GFx320 Optical Gas Imaging (OGI) camera offers gas leak detection performance using its High Sensitivity Mode (HSM).

High Sensitivity Mode is based upon an image subtraction video processing technique that effectively enhances the thermal sensitivity of the camera. The HSM feature subtracts a percentage of individual pixel signals from frames in the video stream from the subsequent frames, thus enhancing the differences between frames, which make leaks stand out more clearly in the resulting images. Using the high sensitivity mode even the smallest of gas leaks can be spotted using a GFx 320 OGI camera.

The FLIR GFx320 offers quick, non-contact measurement of gas leaks in real time. Where many other measuring instruments only present users with a number, the FLIR GFx 320 presents visual information, making the leak detection process more intuitive. Optical gas imaging cameras can also be used in hard-to-access locations, since they can detect small leaks from a distance. Unlike restricted point measurement provided by ‘gas sniffers’ a GFx320 OGI camera allows you to detect gas leakage anywhere within the field of view of the camera. This accelerates the process of inspection for gas leaks considerably.

The GFx320 is independently certified as intrinsically safe, allowing for quick detection of gas leaks while maintaining safety inside hazardous locations. The GFx320 visualises small hydrocarbon leaks with the sensitivity needed to meet the US EPA’s OOOOa methane rule. Finding and fixing these leaks can save companies thousands of dollars in lost gas and lost profits.

FLIR Systems specialises in technologies that enhance perception and awareness.  The company brings innovative sensing solutions into daily life through its thermal imaging and visible light imaging technology and systems for measurement, diagnosis, location and advanced threat detection.  Its products improve the way people interact with the world around them, enhance productivity, increase energy efficiency and make the workplace safer.

FLIR Systems has six operating segments – surveillance, instruments, OEM and emerging markets, maritime, security and finally, detection. Of these six, ‘instruments’ is of greatest interest to trade and industry and the second largest segment in the company’s portfolio. This division provides devices that image, measure and assess thermal energy, gases and other environmental elements for industrial, commercial and scientific applications.

These products are manufactured across five production sites, three in the USA and two in Europe; Sweden and Estonia.

A model to suit every application and budget
The options that FLIR Systems provides for measuring temperature and studying thermal performance have never been greater.  Not only does the company offer a huge range of models to suit all thermal application needs but the technology is also affordable and very easy to use.  Thermal cameras now come in various shapes, sizes and degrees of sophistication and FLIR continues to invest heavily in the development of new and complementary technologies to differentiate itself from competitors.

An important milestone in the development of thermal imaging has been the introduction of the FLIR Lepton® core, a micro longwave detector, the size of a mobile SIM.  This has allowed thermal imaging to be repackaged to meet the needs of an even wider audience and, in combination with another new technology called Infrared Guided Measurement – IGM™ – has led to the development of a range of test and measurement meters with imaging capability.

Another important growth area for FLIR thermal imaging is in continuous monitoring to assure quality and safety.  Through its introduction of discrete fixed mounted thermal cameras which are fully compliant industry standard plug-and-play protocols, FLIR Systems has provided industry with infrared machine vision which is instantly ready for quick and easy network installation.

Protecting assets and people from fire is an area for which thermal imaging is least known but, thanks to FLIR Systems’ development, it is now one of the most cost-effective methods available.  Its application flexibility and rapid return on investment present an attractive proposition for any site or safety manager.
