Dayu Electronics; How the M26 Hydrophone Monitors 24/7 to Pinpoint Leaks in Water Supply Networks

For an invisible water supply network, the biggest fear is not the leak itself, but the leak that goes undetected for a long time.

Manual inspections are slow, positioning is inaccurate, and nighttime leaks are even harder to hear—leakage is like a bill that keeps deducting charges, silently draining water resources and operational costs. The value of the M26 hydrophone lies in turning "passive detection" into "round-the-clock surveillance": it continuously collects leak vibration signals 24/7 and, combined with data analysis, locks the leak location to a sufficiently accurate range.

Let's first clarify its working logic: when a leak occurs, the fluid inside the pipe generates specific vibration and acoustic signatures. The M26 hydrophone, based on piezoelectric ceramic technology, captures these "weak but real" signals with high sensitivity, and uses 16-bit resolution acquisition (dynamic range ≥96dB) to record subtle changes, providing a high-precision data foundation for subsequent identification and localization.

In practical applications, we deploy the M26 hydrophone and pressure sensors on the same pipe segment. The hydrophone captures the acoustic frequency generated by the leak, while the pressure sensor monitors fluctuations in pipe pressure. The two data streams are aggregated and cross-analyzed through algorithms—like performing a "CT scan" on the pipe. The system comprehensively determines whether a leak exists and precisely calculates the leak location based on the time difference of acoustic wave arrival at different sensors.

In terms of installation and maintenance, it is more like "close listening" rather than "major surgery."

The M26 hydrophone supports non-invasive monitoring, installed on the outer wall of the pipe with a clamp-type fastener—no water shutdown required. The entire unit consumes ≤150mW and can operate long-term with solar power. A four-core shielded cable transmits signals, using structural measures to suppress electromagnetic noise interference. For maintenance teams, this means faster deployment, less impact on water supply, and more manageable long-term maintenance pressure.
