旋翼式水表倾斜安装对计量性能的影响

摘要

The influence on measurement performance of DN15-25 rotating water meters with ifxing tilt angle is analyzed. This paper presents the difference of metering errors between the water meters which are ifxed in a horizontal way and water meters which are ifxed in an inclination way by the testing data from laboratory.The result can promote water meters to be ifxed on the spot and improve the measurement accuracy of water meters.%通过实验室开展的试验性研究,分析上海地区使用DN15-25小口径民用旋翼式水表以不同径向倾角安装后,对计量误差所产生的影响.通过实验室测试、数据分析,对水表水平安装与不同的倾斜角度前后进行数据对比,分析水表计量误差发生的变化,从而提出进一步规范水表的现场安装,提高水表计量准确性的论点.
