Ultrasonic Leak Detectors
PRODUCT OVERVIEW
The Flex.US Ultrasonic Leak Detector is a hand held, high quality compressed air leak detection system that has all the features necessary for flexible use in finding costly air leaks.
The FLEX.US ultrasonic leak detector kit comes with the FLEX.US unit, carrying case, and manual and utilizes two AA alkaline batteries(included). The FLEX.US is a complete kit – the high quality flexible sensor is mounted on the end of a flexible steel pipe so the ultrasonic sound can access hard to reach areas. The unit converts the ultrasonic noise of a leak into a sound humans can hear (hissing sound) and not just some beeping sound or LED display that may not distinguish a leak sound from other phenomenon.
The headset has excellent noise attenuation for use in the noisiest of environments.
A rugged carrying case protects your FLEX.US when not in use.
The FLEX.US is a solid tool – built to last, it is easy to use and will provide many years of service.
The Flex.US Ultrasonic Leak Detector has the sensor on the end of a flexible pipe to allow detection of leaks in difficult to reach areas.
The Ultrasonic Leak Detector comes in a handy carrying case to store the unit and quality headphones. The headphones are durable and of high quality to cut out extraneous noise that would make it difficult to detect leaks.
Quality head phones block out plant noise to make it easy to listen for, and locate an air leak with the Flex.US system.
HOW ULTRASOUND WORKS
Ultrasound is beyond human hearing capacity. Most humans hear frequencies from 2- Hz to 20 kHz. Ultrasonic sound is beyond thisrange at 20 kHzto 100 kHz. The FLEX.US unit convertsthe ultrasonic sound to an audible range to humans. Compressed airleaks generate thisrangeof ultrasound “noise” thatthe unit picks up.

WHY OUR ULTRASONIC LEAK DETECTOR DOES THE JOB AND WHY OTHERS MAY NOT
REMEMBER
The better the system, the more leaks you find and the more money you save! Always beware of cheap ultrasonic leak detectorsthatjustmay not do the job.Ours doesthe job because ofthe following
FIRST
Look at the headphones. If they are an open walkman style,these will be useless in a noisy plant because they offer absolutely NO protection from the ambient noise which can be at high levels! (After all, why else would you need an ultrasonic lead detector!) So how can you hear the leak in the headphone without protection from the ambient audible noise in the plant? Our headphones completely cover the ear providing 130 dBA hearing protection. Some competitive units would not be useable in a typical factory where hearing protection is mandatory because the inspector would have to insert ear plugs in his ears. Our headphones don’trequire this.
SECOND
Look at frequency range. Our frequency is centered at 38.4 kHz with an open window of +/- 2 kHz. By having a bandwidth this narrow we are able to eliminate other sources of ultrasonic parasite noise. It is absolutely critical that you amplify just this narrow single harmonic band ofsound. Some detectors amplify every frequency from 20 kHz up to 100 kHz. That’s because the manufacturer did not include any low pass filters. This also affects the output signal in the headphones. It also affects the directionality of the device. At low frequency it is much more difficult to know where the sound is coming from because the wavelength is larger andmore reflective.
Quality head phones block out plant noise to make it easy to listen for, and locate an air leak with the Flex.US system.
THIRD
Extension tubes. For a ccessing tight areas some firms suggest using a hollow tube (tubular extension) with their system. Ultrasound will nottravel well into this tube so the equipment will be lesssensitive in hard to reach areas. Ifthe tube is 6″ long for example, that means the sensor is always a minimum of 6″ away from the source. The Nex Flow™ system sensor is at the end of the flexible extension so the sensor is “always” directly exposed to the leak making our equipment much more sensitive. If more sensitive of course youwillmore easily detectthe leak (one youmay not even find with a nother system.)
