Correlation Leak Detection

Correlation Leak Detection is a technique to find leaks in pressurised water pipes with pinpoint accuracy. A leaking pipe creates a sound which travels along the pipe wall material.

A Leak Noise Correlator works by attaching two sensors on the pipe.

The sensors emit and record a sound via radio to a separate processing unit. The correlator then calculates the location of the leak using a mathematical algorythm.

The calculation is composed of:

  • Signal Delay
  • Sensor Distance
  • Sound Velocity
The calculation tells the operative how far along the pipe the leak is from each sensor.

What Type Of Leaks Can Be Located Using Leak Correlation?

Leak Noise Correlators are highly technical pieces of equipment that can be used to locate water leaks over long distances.

Our engineers use Leak correlation devices to detect leaks on water mains and large irrigation systems.

Do Not Delay – Call ADI Leak Detection Today


The longer any leak is left unattended, the greater the risk of significant damage to your property. 

If you have any inclination that you have a leak but are unable to locate the source of that leak, then call ADI today on 0800 731 3843.
