Gas detection


is delivered around a site by a system of air lines. These pipes are often above ground to improve logistics and ergonomics of production, however over time they can degrade and give rise to leaks. Elbow joints, reducers, condensers, and other fixtures all have the potential to leak air under pressure. With hundreds of metres of pipework, these leaks can often be difficult to detect. Teledyne FLIR are a global producer of high quality analytical handheld devices, including both thermal and acoustic imaging cameras. Released earlier this year, the FLIR Si2-LD acoustic camera makes light work of identifying leaks in pipework, even those elevated air lines that are difficult to access. By simply pointing the camera at an airline it can detect leaks of 0.05

litres per minute at a distance of 10 metres. At 2.5 metres, leaks as little as 0.0032 litres per minute can be detected. These may not sound like very big volumes, but over the course of a year the loss can be considerable. On the FLIR Si2-LD, air leaks are displayed on the high defi- nition five-inch colour screen, by simply pointing the handheld device at the air line. Teledyne FLIR not only produce a wide range of high quality cameras but also provide the associated software to facilitate the collection and analysis of data. The FLIR Si2-LD camera is loaded with such software. Using a system termed Industrial Gas Quantification, the camera can calculate the monetary loss incurred for each leak identified. As well as air, the software can also


calculate losses for a variety of other gaseous systems including ammonia, helium, hydrogen, argon and carbon dioxide.


If your company is one of the many thousands, that are concerned about their carbon footprint then reducing electricity usage through eliminating air leaks might prove to be an example of low hanging fruit. The Si2-LD from FLIR is a vital tool is facilitating this move to protect our environment. To find out more about the SI2-LD acoustic camera and other instruments in the Teledyne FLIR range please contact your local agent or your FLIR distributor.
