What happens during an ultrasonic air leak survey?
Handheld instruments used for an ultrasonic air leak survey detect the turbulence created as the compressed air passes the leak site. These sensitive instruments can “hear” the noise generated by this turbulence from over 30m away. Since the noise generated is a short wave high frequency signal it cannot be detected by the human ear.
The instruments used are directional. This means that when the instrument is pointing towards the noise source the reading is louder. As we move closer to the leak site the noise becomes louder. With a wide dynamic sensitivity range compressed air leaks can be identified quickly and easily.
An ultrasonic air leak survey is quick and non intrusive. Typically, a 20,000 sq ft factory with a basic compressed air line setup can be surveyed in 90 minutes or less.
How do you detect such a small leak?
Once the general leak area is identified, the technician moves closer to the noise source adjusting the sensitivity of the device. A number of attachments can also be used on the instrument to assist in pinpointing the exact leak point. The reading on the device indicates the severity of the leak in decibels (dB). Single click technology allows for quick storage of the data in the device.
The higher the dB reading, the worse the leak and the more energy being wasted.
The Report
The data stored in the Ultraprobe 3000 is simply downloaded to a computer or laptop via a USB Port.
The Unique Data Management Software contains site specific information. You provide details of your working patterns and rate paid per kWh for electricity. This allows the software to accurately calculate the true cost of each leak together with its associated CO2 emissions.
The information can be used to generate a schedule for repairs. This schedule will allow you to tackle the worst leaks first to start saving money quickly. Smaller leaks can be repaired later spreading the cost over a longer period.
