Leak Detection saves time and money

Today’s sophisticated leak detection technologies allow for the ability to pinpoint leaks without the hassle and expense of digging up and damaging your property.

Leak detection has many advantages over traditional methods of leak finding, including

There are 3 methods used for leak detection

Correlation

A leak in a pipe under pressure creates noise that travels along the pipe and through the surrounding ground.

Two highly sensitive microphones are attached to the leaking pipe.

The sound from the leak takes longer to travel to the microphone furthest from the leak.

The correlator uses the ‘’time delay’’ to pinpoint exactly where the leak is situated.

Acoustics

When a pressurised pipeline leaks, the water gushes/pushes out of the crack/damaged pipe into the surrounding ground.

The pipe material vibrates at the leakage point.

These vibrations are transmitted by the pipe and can even be noticed at distant contact points. Eg. Fittings.

This is known as structure-borne sound and is made audible by an acoustic listening device.

Tracer Gas

A tracer gas consisting of a mixture of hydrogen and nitrogen iss introduced into the water pipe with the suspected leak.

The tracer gas containing hydrogen (which is the smallest and lightest molecule in the atmosphere) will exit at the leak point and make its way to the surface where it is detected by the highly sensitive gas detector.
