新疆喀什市灌区自动化测流设备选型

Selection of Automatic Flow Measuring Equipment in Kashgar Irrigation District,Xinjiang

为推进喀什市灌区水利信息化的发展,结合喀什灌区渠道实际情况,对多种测流设备进行选型研究。结果表明:在喀什市灌区干、支渠宜选用雷达表面测流设备、斗渠宜选用电磁式全渠宽测流设备,通过灌区当地进行的自动化测流方式和人工测流方式的测流数据对比试验,两者测量的水位流量关系曲线接近,最大误差不超过10%,两种自动化测流设备稳定可靠,对测流设备在灌区的应用具有参考意义。

In order to promote the development of water conservancy information in Kashi irrigation district,the selection of various flow measuring equipment was studied in combination with the actual situation of Kashi rrigation district.The results show that:In the dry and branch canals of Kashi irrigation district,radar surface current measuring equipment should be selected,and electromagnetic full channel width current measuring equipment should be selected for the canals.Through the comparison test of current measuring data between automatic current measuring method and manual current measuring method conducted locally in the irrigation district,the relationship curves of water level and flow measured by the two methods are close,and the maximum error is not more than 10%.The two automatic current measuring equipment are stable and reliable.It has reference significance for the application of current measuring equipment in irrigation area.
