Questions about the MWL 500 water leak detector

Where can the MWL 500 find leaks?

The MWL 500 is designed for outdoor water pipelines and finds leaks on buried pressure pipes at depths of up to 5.0 m by picking up the leak noise with its medium sensor and filtering out background noise.

How long does the MWL 500 battery last?

The rechargeable lithium battery gives about 15 hours of work and charges over USB at 5 V 2 A. The main unit weighs 0.7 kg and works from -20 to +50 °C, and the kit includes noise-cancelling headphones, a telescopic pole and an aluminium flight case.

Should I use General Detection or Locating Mode on the MWL 500?

Use General Detection (census) mode to survey a length of pipeline and find the noisiest section, then switch to Locating Mode to narrow it down to the most likely leak point; the 10-level gain control helps on noisy sites.

Case study: finding a leak on a buried water main

In a typical leak search, a water utility or site maintenance team is losing treated water through leaks on buried pressure pipes that rarely show at the surface.

An acoustic leak detector picks up the sound of water escaping under pressure with a ground sensor and filters out environmental background noise. Its touch screen shows the signal and spectrum, so the operator can see where the leak noise is strongest rather than relying on hearing alone.

In the field, the operator walks along the pipe route, places the sensor at intervals, and compares readings point by point. The location with the highest leak signal marks where to excavate, which keeps the dig small and the repair targeted.
