FLIR Systems has published a new white paper that addresses common questions about quantitative Optical Gas Imaging (qOGI).

Historically OGI cameras have been limited to qualitative analysis, meaning that if a leak of a particular gas is occurring, there is little indication of how much is leaking. Recently through the combination of an existing OGI camera with an algorithmic qOGI solution, visualisation and quantification of mass and volumetric leak rates, as well as concentration over pathlength (ppm per meter) is now possible.

The white paper explores how a leader in the Oil and Gas industry has field tested the technology, exploring its viability for quantifying everything from upstream Information Collection Requests (ICR), tank emissions that are difficult to monitor leak detection, repair components (downstream) and maintenance/reliability monitoring.  This field testing demonstrates that while qOGI is a young technology, and no U.S. regulatory driver yet exists for its usage, its merits as a quantitative gas leak measurement tool are clear.

In addition to its obvious safety benefits over alternative gas quantification methods, qOGI has been through rigorous third-party testing from CONCAWE3 and proven to be easier, quicker, and more accurate than technologies like a Toxic Vapor Analyzer (TVA). qOGI is also cost-effective as an add-on to existing OGI cameras and positions oil and gas operators to be at the forward-thinking edge of environmental consciousness in the communities where they operate.

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.
