| 摘 要： | 为提高灌区用水计量工作的水平,对流速仪量水、闸门量水、量水槽量水三种方法进行了对比试验。结果表明:流速仪量水平均误差为4.96%,闸门量水平均误差为6.70%,量水槽量水平均误差为1.15%。相比之下,量水槽测流操作最为便捷,且精度最高,建议有条件的灌区优先采用量水槽测流。

| Abstract: | The experimental research on methods of measuring water was performed in the article to promote the work of measuring irrigation water.The average error measured by current meter is 4.96 %.The average error measured by gate is 6.70 %.The average error measured by flume is 1.15%.By contrast,the measuring flume is the best,not only because of the high precision but also convenience.The paper recommends that the measuring flume is the first choice for measuring irrigation water if the conditions permit. |
