This research paper proposes a new on-line detection technology for flow meters in water supply networks based on the principle of district metering area and mass balance. The mathematical models developed for this technology were successfully validated through different tests, confirming the correctness of the theoretical analysis and the feasibility of the proposed technology. The advantage of this technology lies in its ability to achieve online remote verification of water meters without the need for standard devices, accurately diagnose water meters that are out of tolerance, and provide more accurate data support for water metering in the water supply system.
