The water meter is composed of iron casing, movement and copper parts. When purchasing a water meter, you should first check whether the product has a manufacturing license for measuring instruments with the CMC mark, and the newly installed water meter should also have the first verification mark of the water meter; secondly, check whether the copper parts such as connecting pipes, connecting nuts and copper covers that affect installation safety are Thin, if necessary, you can entrust the relevant departments to test to see if it meets the safety standards, and whether there are problems of cutting corners and endangering the safety of use.
First of all, you should check whether the product has the manufacturing license of the measuring instrument with the CMC mark, and the newly installed water meter should also have the first verification mark;
Secondly, check whether the copper parts such as connecting pipes, connecting nuts and copper covers that affect the safety of installation and use are thin. If necessary, you can entrust the relevant departments to test to see if they meet the safety standards and whether there are any problems that cut corners and endanger the safety of use. .
In the process of use, to check whether the water meter is accurate or not, people can sometimes check it with a more convenient and reliable container or weighing apparatus, or send it to the water meter verification station and measurement technical institution 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 factors such as water quality, pipe material and whether the installation meets the requirements. Users who use intelligent remote water meters or prepaid water meters should also pay attention to product requirements and usage tips, such as timely replacement of batteries, etc., and do not use some crooked brains to "steal" water, because many products are already designed. Anti-theft measures, malicious disassembly and assembly may be punished by shutting down the valve and reducing the amount of water available.
In cold winter areas, water meters installed outdoors should take measures to keep warm and prevent freezing. If the frozen glass of the water meter is broken, it should be sent to the relevant department to replace the movement and glass, and re-check.
