Air Leak Detection

Ultrasonic Compressed Air Leak Detection

Pneumatic Engineering conducts ultrasonic compressed air leak detections on all compressor systems. Leaks in compressed air systems are a significant source of wasted energy, sometimes accounting for 20-30% of your compressors output. An air leak detection audit is simple, fast, and accurate. The results will help your compressor run more efficiently and provide substantial savings.

Why Conduct an Air Leak Detection?

Since air leaks are almost impossible to see, other methods must be used to locate them. The best way to detect leaks is by using an ultrasonic acoustic detector. It can recognise the high frequency hissing sounds associated with air leaks. These portable leak detectors consist of directional microphones, amplifiers, audio filters, and have either visual indicators or earphones to detect leaks.

The principle behind ultrasonic leak detection is simple. In a pressure or vacuum leak, the leak flows from a high-pressure laminar flow to a low-pressure turbulence. This turbulence generates a white noise. The sensors in our detectors focus on just the ultrasonic elements in the noise. This means leaks can be heard in even the noisiest environments because background noises in the audible range are filtered out.

The sound level will be loudest at the leak site because ultrasound is a short-wave, directional signal. It is possible to quickly home in on a leak site and pinpoint its location. This makes ultrasonic leak detection is not only fast, but also very accurate.

The main advantages of ultrasonic leak detection include versatility, speed, ease of use. The ultrasonic leak detector has the ability to performed tests while the equipment is running, and the ability to find a wide variety of leaks.

We will provide you with a detailed report containing the exact location, volume loss and calculation of the annual cost of all leaks in your compressed air system.  It’s not uncommon to see a leak rate of 20%-30%. By keeping up with leak detection and repair, it can reduce leaks to less than 10% of your total compressed air production.
