How to prevent and quickly locate water meter self-rotation or measurement errors through technical means?

1. Remote Monitoring Platform: The company's developed intelligent remote reading terminal can upload water pressure, flow rate, and pointer status data in real time.  It automatically alarms when abnormal fluctuations occur, facilitating timely troubleshooting.
Gas Discharge Valve and Water Hammer Arrestor: Installing an automatic air release valve and a water hammer arrestor at the pipe inlet significantly reduces self-rotation caused by air and impact.
2. Regular Professional Calibration: It is recommended to perform a metrological verification every 2-3 years, especially after replacement or repair, to ensure the meter operates within the specified error range.
3. On-site Inspection and Maintenance: For water meters with frequent pointer fluctuations, conduct on-site inspections to check for leaks, abnormal pressure differences, or installation tilt, and perform necessary repairs or recalibration.
