Innovative technologies

The principle of the acoustic water leak detectors:
When a pressurized underground water pipe develops a leak, water flows through it into the surrounding soil at high speed. In consequence:

The pipeline material vibrates at the water leak. This vibration is transmitted through the pipe, and can be picked up even at remote contact points (water valves, hydrants, water meters, etc.). The sensitive headphones, microphone and amplifier with noise filters helps the user determine water leak location.

The water leak jets and pipes induce vibration in the soil which transmits to the surface, where it can be picked up as ground-borne noise.

Structure-borne water leak noise is transmitted over long distances in metallic pipes. The test rod with a special microphone picks up structure-borne sound very effectively.

Water Leak Detection with the ground microphone

Structure-borne water leak noise is not transmitted as well by non-metallic pipe materials. Taking readings at the valves is not enough: the sections between valves must also be checked with a ground microphone.

Using the ground microphone at brief intervals enables the water leak to be detected and located with sufficient accuracy.

The AQUAPHON^® EW receiver displays the water leak noise level both graphically and with a number including displaying the level of the last reading for comparison. The graphical bar display across the top also shows the lowest current sound levels and indicates the lowest sound level during each reading. This is a primary indicator of water leak location since the background noises vary, but the water leak noises are constant. Finding the location where the minimum sound level is the highest is an important key to water leak detection.
