Adelaide Pipeline Maintenance Services commitment to offer continual customer satisfaction has allowed us to expand our range of equipment to incorporate a new state of the art, raidodetection pipe, cable and leak detection unit.
The radiodetection unit enables us to provide an advanced technical service solution for problem pipe and drain locating as well as under floor ground leak detection.

Our Radiodetection RD4000 pipe and cable locating unit has many built in features allowing for varied applications for differing services including;

  • transmitter clamps - for safe application to live cables
  • reciever clamps - for cable identification in duct, etc
  • flexrods - for pushing sondes down non-metallic and cast iron pipes

The RD4000 is ideal for:

  • Locating of various constructed pipes and drains to depths of 3m, including; PVC plastic, HDPE/Blue brute, cast iron, steel or concrete
  • Checking for buried cables prior to excavations
  • Finding leaking pipes under concrete or natural ground
   
 
   
 
   

 

 

  
   
 

Electro Acoustic Water Leak Detection
Location with the ground microphone
Strucure-borne sound is not transmitted as well by non-metallic pipe materials. Taking reading 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 leak to be located with sufficient accuracy for excavation. The AQUAPHON© ELW receiver indicates a precise optical comparison of the noise intensities.

The hearing-protection function
Operator protection is integral to the AQUAPHON© ELW. It's a common problem: the test rod slips off the contact point, or the headphones are activated too soon or not soon enough. Another example: some object falls onto the ground close to the ground microphone. Both cases expose the ears to unpleasant sound pressure, which may even permanently impair the hearing. The new hearing-protection function of the AQUAPHON© ELW makes this a thing of the past.

The noise signal is constantly analysed. With very loud noises the sound in the headphones is immediately muffled - and if signals are both very loud and sudden, the headphones are switched off. Once this noise source has ceased the ELW reverts to normal functioning.

The filter-optimisation function
When a leak noise is detected with the ground microphone but the noise is too diffuse for it to be located exactly, the filter-optimisation function of the AQUAPHON© ELW facilitates location to the point where excavation can begin. Briefly holding down the "Hz" button makes the ELW take a noise sample with the ground microphone. This is automatically analysed, and the device then spontaneously sets the frequency range which makes the leak particularly vivid.
