The PQWT-L50 Electronic Water Leak Detector is a professional-grade instrument designed for precise detection of water leaks in plumbing systems. Using advanced acoustic technology, this portable device helps identify leak points through sound analysis and visual signal display.

This electronic leak detector operates by collecting and analyzing sound signals from potential water leaks. The sensor captures acoustic data, which is processed by the host unit and displayed as visible spectrum and signal bars on the screen. Simultaneously, audio output is transmitted to headphones, enabling technicians to combine auditory and visual cues for accurate leak detection.

1. General Mode Detection: Scan the entire pipeline using General mode. Monitor headphone sounds and cursor signal display to identify suspected leak points where audio becomes louder and cursor signals increase.
2. Locating Mode Verification: Use the 24 fixed frequencies in Locating mode to verify suspected leak points. For 8kg pipeline pressure, select approximately 800Hz as center frequency and identify the strongest signal point as the excavation location.
