First of all, check whether the product has the manufacturing license of measuring instruments marked with CMC, and the newly installed water meter shall also have the first verification mark of water meter;
Secondly, it is necessary to check whether the materials of copper parts such as connecting pipe, connecting nut and copper cover that affect the installation and use safety are thin. If necessary, relevant departments can be entrusted to inspect them to see whether they meet the safety standards, whether there is any problem of cutting materials and endangering the use safety.
In the process of use, people can sometimes check whether the water meter is accurately measured with a convenient and reliable container or weighing instrument, or send it to the water meter verification station and the measurement technical organization for verification. However, the accuracy of the water meter in use is not only related to the meter itself, but also may be related to water quality, pipe material and whether the installation meets the requirements. Users who use intelligent remote water meters or prepaid water meters should pay attention to product requirements and use tips, such as timely replacement of batteries, etc., and should not use some crooked brains to "steal" water, because many products have anti-theft measures in design, and the behavior of malicious disassembly and assembly may be related to the punishment of valve stop using water and reducing available water.
In cold winter area, the water meter installed outdoors should be kept warm and antifreeze. If the water meter is broken by the glass of the frozen meter, it shall be sent to the relevant department for replacement of the movement and glass, and re verification.
As a fair measuring instrument for water trade settlement, water meter products ensure the interests of both consumers and water suppliers. After the new water meter is used for a period of time, its measurement performance will be affected by many aspects, and there are also technical requirements in product standards and verification regulations.
