More Details
Leak Noise Correlator-LC-5000 finding an underground water leak can become difficult when there is no visible water at the surface. The leak may be several metres away from the nearest valve, hydrant or access point, while traffic and other background sounds can make conventional listening methods harder to use. The Leak Noise Correlator LC-5000 provides a more advanced way to locate hidden water leaks by comparing the sound arriving at sensors positioned at different points along a pipeline.
FUJI TECOM developed the LC-5000 as a digital four-point real-time correlation leak detector. When four sensors are deployed, the system can perform six correlation paths simultaneously and display the results on one screen. This allows technicians to compare several possible leak positions and cross-check results without repeating each measurement separately.
The system also includes logger operation, relay communication, GPS-supported sensor positioning, a 7-inch touch display and rechargeable batteries, making it suitable for professional water-network surveys and difficult field environments.
Nassguard supplies the Leak Noise Correlator LC-5000 across Qatar and Doha, including Doha (Ad Dawhah), Al Rayyan, Al Wakrah, Al Khor, Al Shamal, Umm Salal, Al Daayen and Al Shahaniya for utility authorities, water-network contractors, facility-management companies and leak-detection specialists.
What is a Leak Noise Correlator?
A Leak Noise Correlator is an acoustic water-leak detection instrument used to calculate the approximate position of a hidden leak between two or more measurement points on a pressurised pipeline. When water escapes through a crack, damaged joint or other opening in a pressurised pipe, it creates vibration and acoustic energy. That sound travels in both directions along the pipe. The LC-5000 uses sensors positioned on accessible pipeline fittings such as valves, hydrants or meters. Each sensor captures the leak noise reaching that location.
Because the sensors sit at different distances from the leak, the sound reaches each sensor at a slightly different time. The correlator analyses this arrival-time difference, together with information such as pipe length, diameter and material, to calculate the likely leak position. This method allows technicians to investigate underground leaks without immediately opening large sections of road or ground.

How Does LC-5000 Work?
The LC-5000 works by comparing leak noise recorded at different positions along the same pipeline. First, technicians identify accessible fittings on the pipe, such as valves, hydrants or meters. Sensors are then attached to those locations. Strong magnetic mounting helps create good contact with compatible metallic fittings. When water escapes from a pressurised pipeline, the resulting noise travels along the pipe in both directions.
The sensors receive that sound at different times. Next, the main processor analyses the time delay between the signals. The operator enters relevant information such as pipe material, pipe diameter and distance between sensors. Using these values, the correlator calculates where the leak is most likely located between the measurement points. With four sensors deployed, LC-5000 can perform six correlation routes simultaneously. This provides several possible comparisons and helps technicians cross-check the result.
