Ultrasonic Leak Detectors
Ultrasonic leak detectors are used for large gas leaks. Because gas leaks are often noisy, the ultrasonic technology converts the high frequency leak sound to a lower range where the hissing of the leak can be heard through a set of headphones and traced to the source.
Ultrasonic leak detectors are somewhat new to the industry. In order to be successful, this method of leak detection must be performed in an area that is completely quiet. This factor greatly reduces the commonality of ultrasonic leak detectors.
The volume of the leak's sound is dependent on the amount of pressure in the system. The higher the pressure, the easier it will be to hear the leak. Ultrasonic leak detectors can be used to detect any type of gas, including CFCs, HFCs, nitrogen, CO2, steam, and others.
