我公司在水表周检更换时采用了一批量程比达到200的WPD水表,但在使用过程中发现,许多更换后水表的计量结果比原先水表计量的水量有所减少,而且经查询用户的用水情况并未出现明显变化,是不是因为大量程比的水表并不适合这些用户?因此,研究大量程比的大口径水表是否适用于任何大口径水表用户,探讨大口径水表量程比优化及应
Our company adopted a number of WPD meters with a range ratio up to 200 during the weekly inspection of the water meters. However, during the process of use, many of the meters after replacement have a smaller measurement volume than that of the original water meters, and the users’ Is there any significant change in the situation, is not because of the large scale than the meter is not suitable for these users? Therefore, the study of large-scale than the large-diameter water meter is suitable for any large-caliber water meter users,
