民用小口径机械水表每年在全国水表生产总量约占90%左右,水表生产单位要求申报计量器具制造许可证要做型式试验(型式评价),水表生产企业生产的水表要进行出厂检定,技术机构要履行水表在安装前的首次检定、使用周期后续检定以及使用中检验等。文章详细介绍了民用小口径机械水表的检定程序和要求,供有关人员参考。

Minimal-diameter mechanical water meters annually produce about 90% of the total water meters in the country. The water meter production units require to declare the manufacturing license for measuring instruments to be type tested (type evaluation), and the water meters produced by the water meter manufacturers must undergo factory test. To perform the first test before the installation of water meters, use cycle follow-up test and in-service inspection. The article details the verification procedures and requirements of civilian small-caliber mechanical water meters for reference by relevant personnel.
