摘要
介绍了长喉道量水槽的结构、测流原理、设计计算方法以及在江苏省南通市几个灌区 3年多的应用研究成果。实际应用表明 :长喉道量水槽具有稳定的工作性能 ,精度高 ,相对误差小于 5 % ,能满足农用量水设备的精度要求。
long throat flume is recommended nowadays to use in flow rate measurement in irrigation areas for its several advantages over other types of flumes known: ① with a simple flow rate table determined on the flume dimensions, errors of measurement results can be controlled to be less than 5%; ② water head loss over the flume is minimal; ③ this type of flume is suitable nearly to any kinds of channel and is nearly free from floating debris effects.
