为了克服在河渠中实测流量的实际困难,曾建議和試制一种使用簡便的仪器,此种仪器用在水工、水土改良和实騐研究的測騐工作上同样有效,不管水体的情况怎样,只要能滿足一个条件:即測騐地点的河槽必須稳定不变即可。此外,还必須頂先得出流量曲綫。
In order to overcome the practical difficulties of measuring the actual flow in the canal, an easy-to-use instrument has been proposed and trial-made which is equally effective in the testing of hydraulic engineering, soil and water improvement and experimental research. Regardless of the circumstances of the water body, As long as one of the following conditions can be satisfied: the trough of the test site must be stable. In addition, you must first come up with the flow curve.
