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.

Using Ultrasonic Leak Detectors

Ultrasonic leak detectors can be used to detect any type of gas, including CFC, HFC, nitrogen, CO2, steam, and others. 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. In order to be successful, this method of leak detection must be performed in a completely quiet area. This factor greatly reduces the commonality of ultrasonic leak detectors. These particular detectors are always lightweight and portable. They can be carried around by plumbers, who might use them in domestic plumbing situations where a natural gas leak or refrigerant leak is possible. Of course, because of the necessary silence involved, other methods, such as electronic detectors or gas detectors, are most likely attempted first. Being handheld is another characteristic that makes it easier when ultrasonic detectors are employed to seek large gas leaks in industrial environments. In those situations, the piping suspected of leaking may be underground or in the walls, and having easily maneuverable equipment speeds up the process considerably.

Ultrasonic Detector Process

The specific process ultrasonic detectors use to locate gas leaks is called heterodyning. It is incredibly close to the technology utilized by radio transmissions and the ultrasound sonograms parents view their unborn children through. The sound wave that is unheard by the human ear is located by the detector and translated into an electronic impulse that tells the tester where to go. It is a safer option than some detector processes involving open flames and the potential for fire or explosions. This technological advance in leak detection is important because it has reduced the hazardous exposure to chemicals, which occurs with more involved detection processes. Also, with the help of portable ultrasonic leak detectors, technicians with little to no experience can use this product and successfully detect and mark a pipe or vessel that is leaking.
