摘　　要：简述了测控一体闸的设备组成以及测流原理,并对所选测控一体闸在冬灌、夏灌和秋灌期间的测量精度数据进行分析,分析结果表明在不受低温以及泥沙堵塞过滤外壳和滤网的影响下,测控一体闸的测流精度较高。还针对影响测控一体闸测流精度的一些因素,结合具体实践提出建议,为中国各大、中型灌区的决策者提供参考,同时也为将来进一步研究测控一体闸应用的学者提供参考。This paper makes an introduction to the composition of flumegate and it＇s principle of discharge measurement.A comparison is done between the flow rate measured by flumegate and FP201 current meter.Through the analysis to the data obtained in winter,summer and autumn irrigation season respectively,the conclusion is that the measurement accuracy is high with a temperature above 0 ℃ and little sediment blocking the filter.And also some recommendations are put forward to solve the problem.It not only provides references for decision makers in large and medium irrigation districts,but also for the further study to the application of flumegates in china.
