Product Introduction
The PQ125E series water leak detector is a new generation of intelligent detection equipment independently developed by our institute, specifically designed for pressure pipeline leak detection scenarios in municipal, firefighting, and thermal energy applications. Equipped with a multi-sensor configuration, including the dualmembrane resonance sensors DMR-V59 and DMR-H40 , the acoustic resonance sensors RCS-L6 and RC-S3 , and the trace leak detection sensor TLS-H8 , it offers flexible adaptation to various detection needs such as external main pipelines and indoor branch lines.
Leveraging its core technology of precise acoustic signal acquisition and intelligent analysis algorithms, the instrument enables centimeter-level accuracy in locating leak points. It effectively addresses industry challenges in detecting leaks in both outdoor and indoor pressure pipelines, providing an efficient and intelligent technical solution for municipal maintenance, fire safety, and household pipeline management.
