PURPOSE:To detect exactly the water level of dam by a method in which the water level of dam is detected by a water pressure gauge, the detecting points of water pressure and automatically switched by the number of water-pressure pipes, and the water pressure detected is corrected to measure...
A weir (sometimes called an "overflow dam") is a small dam that is often used in a river channel to create an impoundment lake for water abstraction purposes and which can also be used for flow measurement or retardation.【参考译文】堰坝(有时称为“溢流坝”)是一种小型水坝,通常用于河道中创...

high flow velocity and local vortexes are also factors involved. Despite this, measurements are usually repeated 2–4 times to guarantee accuracy. With the elapse of time, the measurement equipment and methods are also upgraded continuously; many manual undertakings are replaced by automatic procedures...
