A Quality Ultrasonic Leak Detector
This device can be used to locate costly leaks in your compressed air system. Eliminating compressed air leaks can recover a tremendous amount of energy that can be used to operate all types of nozzles, amplifiers and vortex tubes with no added cost! Air savings means free energy. An Ultrasonic Leak Detector (UDC) is typically a hand-held device that is used to locate leaks by aiming it in the direction of a suspected source of an air leak. When a leak is present, then an audible tone can be heard via the use of appropriate head-phones. The proper head phone is very important as well as sensitivity in order to distinguish air leaks from other phenomena which can be miss-interpreted, and even made worse by potential false displays form and LED or other type of display.
Beware Of Cheap Quality
There is good quality and there is cheap quality. Be very suspicious of low cost units because they may be very limited in their use. Nex Flow offers a high quality unit at an excellent price
Always beware of cheap ultrasonic leak detectors that just may not do the job. Ours does because of the following:
FIRST: Look at the headphones. If they are an open walkman style, it 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 130dB 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't require this.
SECOND: Look at frequency range. Our frequency is centered at 38.4 kHz with an open window of +/- 2kHz. 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 of sound. Some detectors amplify EVERY frequency from 20kHz up to 100kHz. 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 and more reflective.
THIRD: Extension tubes. For accessing tight areas some firms suggest using a hollow tube (tubular extension) with their system. Ultrasound will not travel well into this tube so the equipment will be less sensitive in hard to reach areas. If the 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 you will more easily detect the leak (one you may not even find it with another system.)
THE BETTER THE SYSTEM THE MORE LEAKS YOU FIND THE MORE YOU SAVE.
Nex Flow aims to be the lowest cost where possible but NOT at the expense of sacrificing quality.
Specifications
NEX FLOW “FLEX.US” ULTRASONIC LEAK DETECTOR
The FLEX.US ultrasonic leak detector kit comes with the FLX.US unit 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 and hard to get area. 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.
