目前,中国一般工、农业生产及民用水表使用量最多的是口径集中在DN15~DN150mm的旋翼式湿式冷水水表。实际使用中,往往发现各规格水表,在一个使用周期下来,甚至在不到一个周期时,其计量准确度已发生很大变化,超出允许误差范围,给使用者造成损失和不公。对于这种状况,现在尝试分析其主要影响因素及应对、调节的方法。1.选择水表,工艺质量是基础经过我单位的大量水表误差试验后发现,使用无
At present, the most widely used general industrial, agricultural and civilian water meters in China are rotary-wing wet-cold water meters with diameters ranging from DN15 to DN150mm. In actual use, it is often found that water meters of various specifications come down in a period of use. Even in less than one cycle, the measurement accuracy has changed greatly beyond the allowable error range, causing losses and injustices to the users. For this situation, now try to analyze its main influencing factors and coping, adjusting methods. 1. Select the water meter, the quality of the process is based on a large number of my water meter error test found that the use of
