DESCRIPTION: ==================================== Receiver AQUAPHON® A 100
Electro-acoustic water leak detection 
Innovative technologies The principle When a pressurised water pipe develops a leak the water flows out it into the surrounding soil at high speed, which causes: • The pipe material to vibrate at the exit point. This vibration, or sound, is transmitted by the pipe. This “noise” (called structure-born) can be heard with the AQUAPHON®
A 100 even at remote contact points, e.g. valves. • The water jet and the pipe, in the vicinity of the leak, also induce vibration into the surrounding soil. This “noise” (called ground-born) is transmitted to the surface, where it can be picked up by the AQUAPHON® A 100. The importance of listening Combined with the advantages offered by the graphics of the integral LCD the human ear remains an important tool for assessing incoming noises. Practice enables noises of different types and tones to be differentiated and actual leak noise to be distinguished from extraneous noise. To assist the operator the AQUAPHON® A 100 is supplied with headphones that provide outstanding sound reproduction. Preliminary location using the test rod In metallic pipes structure-born sound is transmitted over particularly long distances. This makes the test rod very effective for preliminary location. 
Location with the ground microphone Structure-born sound is not transmitted very well by non-metallic pipe materials.
Taking readings at the valves with the test rod may not lead to satisfactory results. In these cases, by using the ground microphone, the sections between valves should also be checked.

Using the ground microphone at regular intervals enables the leak to be located with sufficient accuracy for confident excavation. 
The AQUAPHON® A 100 shows a precise display comparison of the noise levels between locations.

Is the noise getting louder or quieter? What is the trend? The LCD digital and analogue display is of great assistance, especially for beginners or less experienced operators, in answering these questions. The hearing protection function When developing the AQUAPHON® A 100 an important consideration was providing the operator with protection from accidental exposure to high noise levels. With other instruments an uncomfortable sound level can be heard when the test rod slips from the contact point, or the headphones are activated too soon, or not soon enough, or something falls close to the ground microphone.

A novel technology makes this danger a thing of the past. The incoming noise is constantly analysed. When a very loud noise is picked up the sound in the headphones is immediately muffled. If the noises increase even further, the headphones finally are switched off completely. Once this noise source has ceased the AQUAPHON® A 100 automatically reverts to normal. The hearing-protection function can be adjusted to suit the wearer´s comfort in any given environment. The filter-optimisation functio The filter-optimisation function of the AQUAPHON® A 100 allows it to detect a leak even when the sound is very muffled. 

The receiver takes a noise sample with the ground microphone. This is automatically analysed and the instrument automatically sets the optimum frequency range to render the sound of the leak particularly clear. Specifications AQUAPHON® A 100 Ground microphone BO-4 Ground microphone 3P-4 Handle H-4 Test rod T-4 with various adapters Noise cancelling headphones Charging station HS   AQUAPHON® A 100 Carrying system "Triangle" The Ground microphone BO-4 is especially suitable for paved surfaces. The outside housing of the microphone is acoustically insulated from the internal microphone. The microphone body is mounted in a flexible rubber membrane which can move freely within the housing and it is therefore unaffected by rugged surfaces.   The Ground microphone 3P-4 is for use on unpaved surfaces. A ground spike (supplied) can be screwed on for use in soft ground. Its tripod foot ensures stable contact at all times. Easy-to-maintain microphones: Cables are wearing parts. Therefore all microphone cables have been designed to be replaced by the field operator. This means low service costs and less down time. Leak detection within structures can involve working in some tight locations. To carry out this work we provide the small, light, microphone EM 30 complete with short probe tip. Also available: Magnet, tripod and compact case. ====================================
