在管理水库和渠道等排灌系统中,往往会遇到用流速仪和浮标测流难以克服的困难,比如:流速太小,水草多,有飘浮物,测时不准等等。为解决上述问题而采用由乌克兰科学院水生生物研究所研究的压气测流法是适宜的。采用该法测流,既可在桥上或涉水进行测量,也可以在船上操作。至于测流时选用什么样的测流装置,则视测流的目的、河流的状况和水利工程的类型不同而异。 (详见示意图) In the management of drainage systems such as reservoirs and channels, it is often difficult to overcome the difficulties of using flow meters and buoys to measure flow, for example, the flow rate is too small, there are many plants, floats, and the time is not accurate. In order to solve the above problems, it is appropriate to adopt a gassometry method which is researched by Institute of Hydrobiology, Ukrainian Academy of Sciences. The method of measuring the flow, either on the bridge or wading measurements, you can also operate on board. As for what kind of flow measurement device used when measuring the flow, then the purpose of the visual flow, the status of the river and the type of hydraulic engineering vary. (See diagram)
