More Details
Finding an underground water leak does not always require opening long sections of road or guessing the repair location. When water escapes from a pressurised pipeline, it produces acoustic energy that travels through the pipe in both directions. By comparing when that sound reaches different sensors, technicians can calculate where the leak is likely to be. The Fuji Digital Leak Correlator LC-5000 is a professional four-point real-time acoustic correlation system developed for underground water-leak investigation.
Unlike conventional two-sensor correlators, the LC-5000 can operate with four sensors and calculate up to six correlation routes simultaneously. All six results can appear on one screen, allowing technicians to compare the suspected leak from several directions during the same survey. The system also provides GPS-supported sensor positioning, logger mode, relay communication, large-pipe filtering and a 7-inch touch display.
Nassguard supplies the Digital Leak 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 water utilities, civil contractors, pipeline-maintenance companies, leak-detection specialists and facility-management teams.
What is Digital Leak Correlator?
A Digital Leak Correlator is an acoustic instrument that calculates the likely location of a hidden water leak by comparing noise detected at different positions along a pressurised pipeline. When water escapes through a crack, defective joint or damaged section of pipe, the leak generates vibration. This vibration travels through the pipeline toward both sides of the leak. Sensors placed on suitable accessible points such as valves, hydrants or fittings detect the sound.
The leak will normally be closer to one sensor than another. Therefore, the vibration reaches the sensors at slightly different times. The correlator measures this arrival-time difference and combines it with information about the pipe to calculate the likely distance from the sensors to the leak. The LC-5000 improves this process by allowing four sensors to work together. With four measurement points, the system can perform six separate correlations simultaneously, helping technicians verify whether several calculated routes indicate a similar leak position.

How Does the LC-5000 Work?
The LC-5000 calculates leak position from acoustic timing differences. First, technicians place sensors at suitable accessible points along the pipeline. These may include valves, hydrants or other fittings that provide good acoustic contact with the pipe. Next, the sensors detect vibration travelling through the pipeline. The main processor receives the signals and compares when the same leak sound reaches each sensor.
The operator also enters relevant pipeline information. Depending on the survey, this can include the distance between sensors, pipe diameter and pipe material. The processor then uses the acoustic delay and pipeline information to calculate the likely leak position. With four sensors installed, six different sensor-pair combinations become available. The LC-5000 processes these routes simultaneously and displays the results together.
