How to calibrate and maintain a mechanical water meter

Mechanical water meters are important tools for measuring water consumption in homes and industries. Regular calibration and maintenance are particularly important to ensure the accuracy and stability of their measurements.

Importance of Mechanical Water Meter Calibration
Water meter calibration is an important step to ensure the accuracy of water measurement. Due to long-term use, the gears, scales and sensors of the water meter may wear or age, resulting in measurement errors. Regular calibration of the water meter can detect and correct these errors in a timely manner to ensure that the water bill paid by the user is consistent with the actual usage.

Basic steps of calibration
Prepare tools and equipment
Some professional tools such as flow standard devices, thermometers and pressure gauges need to be prepared during the calibration process. These tools can help detect water flow rate, temperature and pressure to ensure the accuracy of calibration.
Choose a suitable test environment
The test environment should avoid extreme temperatures and interference factors and maintain stable water flow conditions. The ideal test environment is a laboratory with moderate temperature and no vibration.
Connect the water meter to the flow standard device
Connect the Chinese mechanical water meter to be calibrated to the flow standard device, ensuring that the connection is tight and there is no water leakage.
Gradually increase the flow rate
According to the rated flow range of the water meter, gradually increase the water flow rate and record the readings at different flow rates. Several different flow points are usually selected for calibration tests to fully evaluate the performance of the water meter.
Data recording and analysis
Record the data obtained during the test and compare it with the standard flow rate. Evaluate the accuracy of the water meter by calculating the error percentage. If the error exceeds the specified range, it needs to be adjusted.
Adjust and recalibrate
According to the test results, make necessary mechanical adjustments to the Chinese water meter, including the correction of the gears and the position adjustment of the scale. After the adjustment is completed, it is necessary to calibrate again to ensure that the water meter readings meet the standard requirements.
Daily maintenance of mechanical water meters
In addition to regular calibration, daily maintenance is equally important. The use of correct maintenance measures can extend the service life of mechanical water meters and improve their measurement accuracy.

Regular inspection
At regular intervals, conduct a comprehensive inspection of the Chinese mechanical water meter, including appearance, connecting pipes, sealing, etc. When leaks, corrosion or other abnormal conditions are found, they should be handled in a timely manner.
Cleaning and maintenance
Due to the water quality conditions of the water meter, sediments will appear on the internal components. It is recommended to disassemble the water meter regularly for cleaning. Use appropriate cleaning agents and tools to ensure that there are no impurities and deposits inside the water meter.
Avoid violent impacts
Avoid violent collisions when using and moving the water meter. The precision components inside the mechanical water meter are easily damaged, resulting in inaccurate measurement.
Prevent freezing
In cold environments, water meters are prone to freezing. Therefore, anti-cold measures should be considered when installing the water meter, and the water meter should be wrapped with insulation materials if necessary.
Note on temperature and pressure
Mechanical water meters usually have a specified operating temperature and pressure range, exceeding this range will affect their performance. Therefore, when designing the pipeline, ensure that the water meter works under suitable conditions.
