LC-5000

Powerful Leak Noise Correlator

The Water Leak Correlator is a cutting-edge device designed to revolutionize water leak detection and localization. This advanced equipment employs sophisticated algorithms and acoustic technology to analyze and compare the sound signatures of water leaks in pipelines. By precisely correlating the acoustic signals captured at different points along the pipe network, the correlator pinpoints the exact location of the leak with remarkable accuracy. This non-intrusive and efficient solution not only minimizes water wastage but also reduces the time and resources required for leak detection and repair, making it an indispensable tool for water utilities and infrastructure maintenance teams.

Main Processor Unit

The primary unit is equipped with a 24-bit digital signal processor, which enables expedited correlations. Weighing roughly 5 pounds, this compact device is easily portable throughout the day. It can project up to 6 correlations on a single screen when the 4 transmitters are deployed, and the user can conveniently access each correlation through the touchscreen interface.

Pre-amp/Transmitter

The transmitter is designed to be fully submersible and powered by lithium rechargeable batteries. It can be connected to the main unit using cable or radio mode. Additionally, the operator can attach an external antenna to the transmitter when it is connected to a deeper pipe. The system has logger capabilities and the pre-amplifier can be used as a repeater to expand the radio propagation range even if there is no incidental facility near the leak point.

External sensor and cable

External sensors equipped with a 10-foot cable, which are fully submersible, offer a cost-effective means of collecting noise in deeper, muddier access points to pipes and couplers. This solution is ideal for those who require efficient data collection in challenging environments, where traditional methods may not suffice. With this setup, one can expect reliable and accurate readings, even in the most adverse conditions.
