  三、超声水表与机械水表主要技术性能指标对比:(以DN200水表为例)
快乐飞艇计划软件 10年以上3年无线方式先进可显著机械水表±2%2m3/h0.03~0.1MPa较大2~5年1年磁卡方式不可靠无  四、机械水表改换超声水表后,将在以下两个方面产生显著的经济、社会效益:(以DN200水表为例)

  2.节电效果:机械式水表工作在常用流速1m/s(流量113m3/h)时,产生的压力损失约为0.07MPa,即7m水柱,而超声水表压力损失几乎为0;当供水泵效率为80%,年供水时间约5000小时,按下表所给条件计算,超声水表每年可节电能13457度。按电价0.8元/度计算可节省资金10766元,这又是一个不小的数字;

  3、沈阳水司在铁西维华商场安装了一台DN150超声水表与新检定的机械式水表串联对比,观察发现正常营业时相差不大。在21:30-0:00流量大多处于2m3/h左右,机械式水表间断性计量,而超声水表正常计量;在0:00-8:00流量基本处于2m3/h以下,低于机械式水表的始动流量,而超声水表在0.3方以上是正常计量的。经过两个月的观察,超声水表可挽回损失10%以上。
 
快乐飞艇计划软件   4、沈阳医大二院安装了一台DN150超声水表和机械式水表串联对比,白天流量在2m3/h左右,仅2004年10月,超声水表计量2077m3,而机械式水表仅计量833m3,超声水表比机械式水表高出150%,这说明低流量效果更为显著。
