摘 要:田间末级渠道量水设施的应用日益受到重视,针对内蒙古河套灌区末级渠道量水的特点,从准确性、经济性、便捷性等方面对旋杯式流速仪、文丘里自动量水系统、直读式流速仪、遥测水位计进行比较分析.结果表明:与旋杯式流速仪相比,文丘里自动量水系统、直读式流速仪、遥测水位计测流平均误差为9. 8% ~ 17. 7% ,具有较高的测流精度.4 种量水技术各有一定的适用条件,XD -2206 遥测水位计经济性、便捷性最优;FP211 直读式流速仪、文丘里自动量水系统次之;旋杯式流速仪-次性投资低,但工作效率低、运行费高,已无法满足末级渠道现代化量水需要,急需更新换代.It is very important to generalize the use of accurate, convenient and cheap technology of water measurement of terminal channel in Hetao irrigation area.Cup-type Current Mete, Automatic Venturi Water System, Direct Reading Current Meter and Telemetry Water Level Recorder were anglicized base on accuracy, economics and convenience.The results show that average error of discharge in canal is between 9.8%~17.7%, showing higher accuracy of water measuring equipment.The application condition of every water measuring equipment is different, the economics and convenience of Telemetry Water Level Recorder is the best, Automatic Venturi Water System and Direct Reading Current Meter come second.Cup-type Current Mete is inexpensive in one-time investment, but the efficiency is low and the operating cost is high, it should be taken place by other water measuring equipment.
