Thermal imaging finds swimming pool leak
Flir thermal imaging provided a quick and non-disruptive method of detection when swimming pool in Sardinia was leaking at a rate of almost 19,000 litres per day.
Just before the start of the high tourist season, the administrator of a holiday apartment complex in a popular and exclusive resort in Sardinia was faced with a problem.
The conventional method of finding the source of the leak would involve digging up the pool surround to expose pipework.
However this was a non-starter as it would take too much time, compromise the quality standards visitors expect and preclude them from using the pool.
So an alternative method of detection was needed that would be quick and non-disruptive - FLIR thermal imaging.
Thermography consultant Fabrizio Contino from Termografia Express explained: 'We suspected that the leak was in the pipework that continuously filters out sludge and debris.
However these 60cm pipes extend around the pool, so it was question of pinpointing the exact source of the problem'.
Using the sun as illuminator.
As the initial survey did not show decisive signs of leakage, Fabrizio Contino tried a different tack.
He shut down the outflow to pressurize the water in the pipes and then took two sets of thermal images, two hours apart.
In the heat of the day he hoped that the second images would reveal areas of the pavement that were cooler than others.
And true to expectation that is exactly what the FLIR camera revealed, indicating that the cooler areas were subject to water ingress.
Having identified the potential problem areas, repair work could be properly targeted.
The subsequently exposed pipework was indeed found to be either cracked or broken, validating the findings of the thermographic survey.
It had proved to be a highly effective method of detecting the source of the problem, quickly and with minimum disruption.
The thermal imaging camera used by Fabrizio Contino for this survey was the FLIR E60 thermal imaging camera.
Its microbolometer detector produces thermal images at a resolution of 320 x 240 pixels with a thermal sensitivity better than 0.05degC.
The highly detailed thermal images show any temperature related fault, no matter how small.
With powerful features such as picture in picture and thermal fusion the FLIR E60 is a popular choice for a broad variety of predictive maintenance and building science applications.
'I especially like the fact that I can immediately create reports in the camera', commented Fabrizio Contino.
'With the new thermal imaging cameras from FLIR you even have WiFi connectivity, so I can immediately show the results to my client.
This really is a great plus, allowing me to indicate the exact location of the problem to the client and also to the contractor in charge of the repairs'.
Due to the precise localization and immediate communication of the problem the repairs were swift and the pool was repaired before the guests arrived.
'The use of a thermographic survey with my FLIR E60 thermal imaging camera has saved time, effort and money'.
FLIR thermal imaging also helped safeguard the good reputation of the apartments, according to Fabrizio Contino.
'The alternative would have been to dig up the entire perimeter of the pool, making it unusable for guests.
It would have taken time and cost a lot more money.
Thanks to thermography the pool was ready for use when the guests arrived, without the inspection this certainly would not have been the case'.
According to Fabrizio Contino this is just one of the many examples where the FLIR E60 thermal imaging camera has proved its worth.
'It really is a great tool for a wide range of applications.
I use it for monitoring hydraulic, electrical and mechanical systems and also for building surveys and photovoltaic installations.
Sometimes vets hire me as a consultant and I also cooperate with several medical facilities.
The camera is extremely versatile'.
Fabrizio Contino commends the user friendly design of the FLIR E60 thermal imaging camera, but stressed there's more to thermography than a good camera.
New FLIR Ex and Exx Series thermal imaging cameras for spotting and stopping energy loss will be shown for the first time in the UK at Ecobuild 2014. Offering greater cost efficiency and intuitive performance they provide create an affordable gateway to thermal imaging. FLIR Systems’ patented MSX technology means exceptional quality in real time, plus it adds definition to the image, making troubleshooting quicker and easier.
FLIR’s Exx-Series of thermal imaging cameras has been designed for users who want more than an entry level model but not all of the features synonymous with professional models. Exx-Series models are thermally tunable and manually focusable and feature thermal fusion, continuous zoom, text/voice annotation, WiFi and Meterlink. The range consists of three models – E40, E50 and E60.
FLIR is introducing a special package on its B660 advanced thermal imaging camera which offers cost savings of over £6,000. The package, which includes the camera, a 24° wide angle lens, FLIR’s multi platform, advanced reporting and analysis software, FLIR Tools and the company’s 2-5-10 warranty, is available to professional building inspectors for a limited time only.
FLIR Systems has launched the new FLIR Ex-Series of entry-level thermal imaging cameras which incorporate MSX-technology for exceptional image quality in real time. The FLIR Ex-Series consists of four new cameras which have been designed to be easy to use for those who are new to thermal imaging. The cameras have a fixed focus-free lens and are extremely lightweight, weighing just 575 grams.
Thermal imaging technology can be used to ensure the best possible yield from solar panels. Suppliers can use it to detect shunts which reduce a solar cell’s conversion efficiency and cameras can be employed in the field for inspection use. Solar systems supplier, Solon, uses FLIR’s P-Series camera for shunt detection and FLIR’s T-Series cameras for field inspections.
