Aquaphon A-50 Ground Microphone Kits (Leak Listeners)

Electro-acoustic water leak detection

When a pressurized pipeline develops a leak, water flows through it into the surrounding soil at high speed. As a consequence of this:

  • The pipeline material vibrates at the exit point. This vibration is transmitted by the pipe, with the result that it can be picked up even at remote contact points (e.g. valves & fire hydrants). This structure-borne noise is rendered audible by the AQUAPHON® A50.
  • The water jet and the pipe, in the vicinity of the leak also induce vibration in the soil. This is transmitted to the surface, where it can be picked up as ground-borne noise.

 

Key Benefits

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 50 is supplied with headphones that provide outstanding sound reproduction.

Preliminary location using the test rod

In metallic pipes structure-borne sound is transmitted over particularly long distances. This makes the test rod very effective for preliminary location.

Using T-4 Test Rod

Leak detection within structures can involve working in some tight locations. To carry out this work we provide the small, light, microphone TS50 complete with short probe tip. Also available: Magnet, tripod and compact case.

Location with the ground microphone

Structure-borne 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 50 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.

EM30 Field Use

The Ground microphone UM50 can be used for paved surfaces.
The special insulated, optuional housing provides excellent protection against background noises.

The hearing protection function

When developing the AQUAPHON® A 50 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 analyzed. 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® A50 automatically reverts to normal. The hearing-protection function can be adjusted to suit the wearer's comfort in any given environment.

The filter-optimization function

The filter-optimization function of the AQUAPHON® A50 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 analyzed and the instrument automatically sets the optimum frequency range to render the sound of the leak particularly clear.
