AI Technical Summary
Water pressure fluctuations in secondary water supply networks can interfere with online water quality monitoring equipment. Existing technologies are unable to effectively suppress high-frequency, small-amplitude fluctuations and distinguish between water quality changes and noise, resulting in inaccurate measurements and slow response.
It adopts a structure of buffer tank, conical fairing, spoiler and wave absorber, combined with Helmholtz resonator and microprocessor to monitor water flow status in real time. By buffering and converting water pressure kinetic energy, it stabilizes water flow and controls sensor operation to reduce the impact of fluctuations.
It improves the validity and accuracy of water quality testing data, extends sensor lifespan, and achieves energy conservation and consumption reduction.
