In the verification process, the verification personnel strictly follow the metrological verification procedures, carefully examine the water meter's appearance and sealability to see if the water meter is leaking. The use of advanced instruments to detect the corresponding indication error, increase the number of verifications for water meters in doubt, to ensure the stability of the water meter.
In the field of metrology work, meter verification is a very important business content. Among them, civilian water meters, electric energy meters, gas meters, and heat energy meters (commonly referred to as “civil metersâ€) are widely used in social production and life. Therefore, their verification work has very important economic and social significance. After vigorous publicity in recent years, more and more users already know the importance of strong inspection. Here, the residents are reminded that the water meter used for trade settlement will only undergo the first-time mandatory verification, and will be used within a limited period of time. The rotation period will expire. The general validity period will not exceed 6 years.
In addition to the inspection personnel of the Xinjiang Tushushuq Bureau of Quality Supervision and Supervision who are highly responsible for the measurement and supervision of metering, the water metering workers in other regions of China are also people-oriented and patient.
The owners who lived in the Times Homestead of Yukuang Lane in the north of Xi’an City, Shaanxi Province, felt that the new water meter for the property had gone faster than the original. Subsequently, the Shaanxi Provincial Quality Inspection Bureau took six water meters with dissenting opinions and took the inspection. Yesterday morning, Shaanxi Province Quality Inspection Bureau feedback test results: all qualified.
Although the results of the six water meter tests are all qualified, in order to allow the owner representative to accept it more frankly, the Shaanxi Provincial Bureau of Quality Supervision invited experts from the Provincial Institute of Metrology, who is in charge of the water meter test, experts from the Xi’an Water Supply Company, and representatives from the water meter manufacturers. Waiting for the courtesy, analyzed the multiple possibilities that would affect the metering methods.
Water supply company experts said that the new meter's metering accuracy and sensitivity have improved by leaps and bounds. The old water meter leaked faucets, line leaks, and water seepage. The internal leakage of the toilet was counted in the total amount of water. With the calculation of the amount of drops, the cumulative amount of water in the 24 hours will reach more than 20 liters. Therefore, under the circumstance that the water use habits and methods have not changed, the total amount of water consumption has increased a lot. We also hope that residents will develop good quality of life. The use of water, close the tap after use, often check the toilet and other water leaks.
Here's a water meter verification method, which is actually very simple and intuitive.
The verification process is such that the inspector puts the water meter to be calibrated on a specific instrument and sets 0.1 tons of water to go from this watch. Finally, the word on the water meter is not accurate. After comparison between the two sides, we can see that the metering is very accurate.
Since the water meter has been calibrated and the measurement is accurate, it indicates that there is something leaking in the user's home. The staff of the water company explained that some users had previously noticed that the amount of water used in the home had increased. Finally, after inspection, it was found that many of them were Because the flush toilet was not reset in time.
Finally, to remind everyone that the current water meter measurement is still very accurate, in the daily life, if some people find that the amount of water at home suddenly become more, it is best to first check the home ware, washing machines and water heaters, these devices are leaking This can also avoid unnecessary waste.
