The other day I performed a Google search for ‘How to detect an air leak’. Not surprisingly it came up with millions of results, over 18 million in fact.
Whether solving the problem in a commercial establishment or a domestic home environment, the majority of search results pointed to one solution. Namely, soapy water!
Before we all ridicule the idea as belonging to a bygone era, take a vehicle with a slow puncture to a tyre fitting depot and the chances are they remove the wheel and spin it in water to determine the leak. It’s a simple time proven method for determining leaks from pressurized systems.
But of course, not all equipment can be placed in soapy water. What if a system is known to be losing pressure and yet the lines carrying the compressed air from the source are located 10 metres above the ground, and dismantling the system is out of the question? Thankfully there is a fast and effective solution to hand.
Each time air or indeed any gas, leaks from a pressured system there is an associated sound. If the leak is significant, it can be audible to the human ear and therefore easily identified and rectified accordingly. However, most leaks in high pressure systems are extremely small and are out of the range of a human ear.
Think about a pressured air system on a large factory delivering compressed air from a bank of compressors to various stages of production throughout the manufacturing process. The chances are there are hundreds if not thousands of connections in the form of joints, reducers, valves, elbows, condensers etc. Each of these has the potential to leak small amounts of air, reducing the pressure of the system.
One leak might make very little difference but multiply this by the number of potential leaking joints and efficiency can be significantly compromised. The compressor will seek to compensate for any pressure loss by simply working harder. However, as any engineer will know, compressors can be expensive to operate in terms of energy and therefore will certainly increase an operators energy consumption.
With electricity costs being so much higher in Europe due to geopolitical factors in recent years, most companies are seeking to reduce the amount of energy used. Having a compressor work overtime to compensate for leaking joints is certainly not something senior management would smile about!
These scenarios are certainly not uncommon, in fact one European compressor manufacturer has stated that in some industrial settings, up to 80% of air generated is lot in leaks. So clearly identifying these small leaks can make a real difference to a company’s energy bills.
Although the sound produced by a small leak is inaudible to the human ear a high performance acoustic imaging camera such as the FLIR Teledyne Si2 – LD will have absolutely no problem identifying the source. Launched earlier this year the camera is capable of detecting leaks of 0.05 litres per minute at a distance of 10 metres, meaning those elevated air lines pose no problem for this latest instrument in the FLIR acoustic imaging camera line up.
For closer work the camera is even more sensitive and can detects minute leaks of 0.0032 litres per minute at a distance of 2.5 metres. Coupled with this improvement, the third-generation camera has improved microphones now capable of detecting sounds over an extremely wide frequency range, namely 2 – 130 kHz.
Areas of plant are often dark or dimly lit. for this reason FLIR have fitted the FLIR Si2-series of cameras with two powerful LED lights to make component identification easy even in poorly lit conditions.
Of course, it’s not just compressed air that the camera is capable of detecting; noise emitted by any escaping gas is identified by the powerful microphones. However that’s only part of the story.
The FLIR Si2-LD has built in software termed Industrial Gas Quantification. If the leaking gas is ammonia, hydrogen, helium, or carbon dioxide, very commonly used gases in a number of industries, the software is capable of quantifying the financial loss caused by the leak. By simply entering factors such as the cost per litre, the software identifies the amount each leak is causing over a given period of time. Such data is invaluable to financial analysts and senior management within an organisation.
It goes without saying that the financial considerations are only one aspect of leaking gas. The gases mentioned above all carry significant health hazards and can present a variety of dangers to personnel if allowed to leak for any period of time. Ammonia and carbon dioxide can cause serious breathing problems and asphyxiation even in smaller concentrations, whereas hydrogen can explode in the presence of oxygen. Clearly the cost of such problems goes way beyond any financial considerations.
We’ve come a long way since the ‘soap and water’ approach. See how the latest technology from FLIR Teledyne can help in reducing downtime, lower energy bills and improve safety in your organisation.

As fall turns to winter, it becomes more important to have a cozy home to retreat to on cold days. However, it may become challenging to preserve a respectable home within one’s budget, given the rising cost of power. Thankfully, there are many options available to reduce heating costs. Here we’ll go through five tried-and-true methods for accomplishing this objective.
Invest in Proper Insulation
Investing in proper insulation is one of the best methods to save money on heating your home. Lack of proper insulation can cause heat to escape, increasing the workload of your heating system. The insulation in your home’s walls, ceiling, and floors should be checked first. Invest in better insulating materials if the current ones are inadequate or damaged. Additionally, ensure that all cracks and openings in windows and doors are sealed. The long-term savings on heating costs from this initial expenditure can be substantial.
Schedule Regular Maintenance
Keeping up with routine maintenance on your heating system is essential to keeping it running smoothly and efficiently. System efficiency decreases with neglect, which in turn increases energy consumption and costs. Get a professional to tune up your furnace to keep it in tip-top shape. They are able to check and clean parts, change filters, and find any problems. Preventing malfunctions and maximizing efficiency can save you a lot of money throughout the life of your system if you maintain it regularly.
Upgrade to Energy-Efficient Heating Systems
An upgrade could be in order if your current heating system is somewhat old. The energy costs associated with heating your home can be greatly reduced by installing a state-of-the-art heating system. You should think about upgrading to a modern, more energy-efficient heating system. Heat pumps and radiant heating are two alternative heating methods worth looking into because of their low energy use. Despite a greater purchase price, this option will prove to be cost-effective over time.
Implement a Programmable Thermostat
You may have greater precision over the temperature in your home by using a programmable thermostat. When you’re not there or asleep, you may set the thermostat to a cooler setting, and when you need it, you can turn it up. When the weather is mild, it’s unnecessary to have the heat on, therefore this helps save electricity. Smart thermostats can optimize energy use by learning your habits and adjusting themselves accordingly. By turning down the heat when it’s not needed, the savings from using a programmable thermostat can be substantial.
Practice Energy-Efficient Habits
A significant reduction in your heating costs may also result from simple lifestyle adjustments. Keeping doors and windows closed when the heat is on, using curtains or blinds to trap heat, and dressing in layers to be warm indoors are all easy ways to reduce your heating needs. Leave the oven door open after you’re done cooking to allow the leftover heat to warm the room. You can save a lot of money in the long run by making these minor adjustments.
Endnote
It is not only conceivable, but also practical, to reduce the cost of heating your home. You can keep your house toasty and warm without breaking the bank if you put money into good insulation, upgrade to energy-efficient heating systems, use a programmable thermostat, adopt energy-efficient practices, and schedule routine maintenance. Your heating costs will go down and your home will be more eco-friendly and sustainable as a result of taking these measures.
