How The CTRL UL101 Leak Detector Works

Using ultrasound detectors for leak detection is a growing industry standard. Ultrasonic leak detection is recommended by many, such as the U.S. Department of Energy, as the best method for detecting the location of leaks in order to minimize energy waste and improve plant efficiency.

The CTRL UL101 Ultrasound Detector converts the ultrasound (40 kHz +/- 1 kHz) down into the audible range and outputs to a headset. All other frequencies are filtered, so that even the smallest air/gas, vacuum, or refrigerant leak can be detected and pinpointed in a noisy plant environment.

Leak Detection Benefits

Other devices require you to be within 1 to 2 feet, to adjust the frequency, to only use for a particular type of gas, etc. The design of the UL101 is "keep it simple." CTRL has designed an easy to use device that is more sensitive than any other and fits in the palm of your hands. 

Easily find leaks in a noisy environment. Ultrasound is very directional. Detect leaks from as much as 150 feet in some cases, depending upon the intensity of the leak. Pinpoint the leak to the exact location in seconds. 

Energy Savings
Reduce your compressor usage by 20% - 30%.

Ultrasound is not affected by wind.

Expensive Gas (Any Type)
Finding one Nitrogen leak has immediate ROI.

Steam Leaks / Steam Traps
Improve steam system efficiency and save money.
