Change the open channel water conveyance into pipeline full flow water conveyance installed the ultrasonic liquid level gauge and pipe flow gauge on the inflow point and surface of pipe water level and discharge would detect in real time .

将测流渠段明渠输水改造成管道满流输水，分别在管道进口前及管管上安装 超声波 液位 计和管道式流量计，将水位和流量实时测出。

Application of Gas Medium Ultrasonic Water Level Gauge in Different River

气介 式 超声波 水位 计在不同河流中的应用

Currently there are many methods to detect water level such as float-type water level gauge pressure-type water level gauge and ultrasonic water level gauge etc.

当前检测水位的方法有许多种，如浮子式水位计、压力式水位计、气介或液介 超声波 水位 计等，在不同的情况下有着不同的应用。

The structure function and working theory of the CCS ⅱ type ultrasonic water level gauge was introduced here . Its practicality and reliability were demonstrated by Nanning hydrologic station .
