direct reading flow velocity and direction meter

Improvement of direct read out current meter and tactics of use and maintenance;

直读式流速仪升级的使用维修对策

With the advanced technologies of electronics,computers,patents and newly developed propeller velocity sensors,multi-function intelligent velocity meters and flow velocity and direction meters adopted in the system,the flow velocity and flow.

该系统应用先进的电子量测技术、计算技术及多项专利技术,采用最新研制的新型流速旋浆传感器、多功能智能流速仪和流速流向仪同步测量大型农业灌区的渠道流速与流量。

Using the reading way that the camera replaces eyes in the test of flow meter with no signal, the testing system of shoot for flow meter with no signal is developed.

针对直读式流量仪表检定问题，采用了摄像头代替人眼读数的方法，研制了直读式流量计的摄像检定系统。
