Electro-acoustic Water Leak Detection Ground and Valve Microphones

The theory of Water Leak Detection using acoustics
Click on any image to enlarge	When a pressurised water pipe develops a leak the water flows out at high speed, which causes the pipe and soil to vibrate at the that point. This sound, or vibration, is transmitted by the pipe, (structure borne) and surrounding material (ground borne). Mechanical listening sticks for detecting water leaks are, at best, only able to detect water leaks that produce very loud noises. However, contrary to common perception it is not always the largest leaks which are the loudest; often a large split in a water pipe produces less noise than through a small hole. This can be particularly true in non metallic pipes. For this reason amplifying the noise with an electro acoustic microphone such as the Aquaphon A100 has become an essential tool in finding water leaks in network With digital circuitry, superior microphone technology and easy to use help features, the Aquaphon ground microphone helps to lessen reliance on the user’s experience allowing them find even the smallest water leak. It has a large digital numerical display allowing the operator to make use of another of their senses, sight - “See” the leak as well as hear it.


AQUAPHON A100 FEATURES
	With some ground microphone instruments an uncomfortable, sometimes dangerous, noise is heard when an unexpectedly loud noise is heard, for leakdetection when somebody bangs their foot wondering if you “can hear that?” The AQUAPHON incorporates a novel technology to makes this danger a thing of the past. When a very loud noise is picked up the sound is immediately muffled. If the sound increases further, the headphones are switched off completely.
	Water Leak Noise Optimised Listening
	We do not all hear best at the same frequencies; some people prefer listening to high frequencies others to lower. Water leaks do not produce noise at the same frequency. Interfering noises make listening at certain frequencies very difficult.
	The Aquaphon has a number of ways to assist with these problems. Suit yourself -Select your own filters By applying your own choice of frequency filters you can listen to any frequency grouping that best suits your hearing the leak noise being listened to. Let the Aquaphon do it - Automatic frequency analysis: The Aquaphon takes a sound sample which is analysed & the optimum frequency range is set and filtered. This can greatly assist those with less experience making the sound of the leak particularly clear.
	Listen to a Water Leak
	Structure borne noise 600 ‐ 2000 Hz
	Ground borne noise 200 ‐ 600 Hz
	Minimum Noise Level
	Current Minimum Noise Level A leak noise does not get quieter but traffic and wind noise fluctuates. The Aquaphon ignores these interfering noises digitally displaying only the “quietest” it has been during the time you have been listening. This is the important value to concentrate on, the real water leak noise Last Minimum Noise Level The previous Minimum Noise Level is stored and displayed Are you closer or further away from the leak in the current listening position compared to the last? Is the leak sound getting louder or quieter? The higher the number on the display the closer to the leak you are.
	A Choice of Microphones
Test rod T-4	Pre-location of Water Leaks: Pre location of leaks is carried out using the test rod T-4 a highly sensitive microphone for listening for water leaks at valves and hydrants.
BO-4 Microphone	Pinpointing on pavements and level surfaces - BO-4 Microphone When the section of pipeline with the leak has been identified, or if you choose to walk the surface of the pipe to find the water leak, pin pointing can be carried out using the wind insulated ground microphone BO-4.
3P-4 Microphone	Pinpointing on uneven surfaces - 3P-4 Microphone On uneven or off road surfaces the 3P-4, complete with ground spike, is the perfect choice; its tripod foot ensures stable contact at all times, reducing interferences from unnecessary vibrations. The 3P-4 can also be used on paved surfaces.
Tripod Adaptor BO-4	Tripod Adaptor BO-4 If off road use is only anticipated as being infrequent there is the Tripod adaptor which fits on the base of the BO-4 converting it into an off road or uneven terrain ground microphone.
EM30	Indoors - EM30 Compact mic with tripod adaptors. Ideal for working indoors with occasional outdoor use
	Sets can be tailored to suit your applications
	Ground microphone BO-4 Ground microphone 3P-4 Handle H-4 Test rod T-4 Noise insulating headphones Charging station Aquaphon A 100 Carrying system "Triangle"
	Plumbers' Compact Kit A useful set for locating water leaks in kitchens, bathrooms and other rooms. This set comes with the EM30 microphone and a tripod which screws onto the end of the EM30 for use on floors. Listening rods can be attached to the EM30 to listen on valves and directly on the pipe. If you intend to carry out a lot of work outdoors it is best to consider the BO-4 outdoor microphone
Aquaphon AF100 - A Water Leak Locator and a Pipe-Cable Location and Tracing Tool
	How many times have you found that utilities marked on network plans are not where they should be when you get out into the field? In order to find the leak in a pipe the first thing you need to find is the pipe itself, so we designed a version of the Aquaphon which is also a pipe locator and tracer. This instrument is called the AF100.The Aquaphon AF100 has all the a features of the A100 described above with the these added functions: CLICK HERE TO DISCOVER MORE ABOUT THE AQUAPHON AF100
