基于大口径表计选型的表观漏失分析研究

Analysis of apparent leakage based on type selection of large caliber water meter

大口径水表计量偏差是供水企业产生漏损率的重要因素之一,通过实验分析了不同型号大口径水表对瞬时流量、计量精度、流量误差、计量性能等参数的影响,为供水企业合理选择大口径表计提供参考,从而提高售水收益,有效降低漏损率。

Deviation of large caliber water meter was one of the important factors of leakage rate for water supply enterprises. Effect of different types of large caliber water meters on parameters such as instantaneous flow, measurement accuracy, measurement error and flow performance were analyzed by experiments, which could provide reference for water supply enterprises reasonable choice of large caliber meter reference, so as to improve the water yield, reduce leakage rate.
