一、试验目的在水表水平安装条件下,不同类型水表安装时,水平倾斜角度的合理范围在标准中并未明确规定。在国际标准中规定倾斜角不能大于3°。而在实际使用过程中,有时水平倾斜角度大于10°,水表仍能正常工作。为此,设计以下试验,以定量评价安装的水平倾斜角度对水表计量性能的影响。 First, the purpose of the test Horizontal installation of water meters, different types of water meters installed, the horizontal tilt angle of a reasonable range of standards is not clearly defined. In international standards, the tilt angle can not be greater than 3 °. In actual use, sometimes the horizontal tilt angle is greater than 10 °, the water meter can still work normally. To this end, the following tests were designed to quantitatively evaluate the effect of the installed horizontal tilt angle on the meter’s metering performance.
