Water Leak Detection and Diagnostics
Acoustic Leak Detection
The acoustic method is one of the most widely used in leak diagnostics.
A ground microphone detects the vibration and sound generated by escaping water, allowing us to pinpoint even the smallest leaks beneath floors or buried pipes.
Additional stethoscope-type devices can be used for direct pipe listening and more accurate localization.
Tracer Gas Method
When a leak cannot be located acoustically or with thermal imaging, the pipe is filled with a tracer gas mixture (5% hydrogen, 95% nitrogen).
The hydrogen escapes through the smallest cracks and is detected by sensitive gas sensors, allowing for high-precision leak localization without destructive work.
Correlation Method
For long or complex water mains, we use correlators that calculate the leak location based on the time difference between sound signals detected at two points.
This method is particularly effective in central and municipal networks.
