为了改变翻斗式雨量计滴定测试设备的落后面貌,南京水利水文自动化研究所最近研制成功了EDY—4型雨量滴定设备。该设备是用来检测翻斗式雨量计的计量误差的。它也与目前国内所使用的“玛里奥特”水箱一样,采用“排水测量法”,但它的稳压原理,滴水精度,排沙清洗,操作方式等各方面都优于“玛氏水箱”。本文将对该设备作一扼要的介绍,以便读者对它有所了解。
In order to change the backwardness of tipping bucket gauge titration test equipment, Nanjing Institute of Water Conservancy and Hydropower Automation successfully developed the EDY-4 rainfall titration equipment. The device is used to detect tipping bucket gauge measurement error. It is also used in the current domestic “Mariotte” tank, using the “drainage measurement method”, but it’s the principle of regulation, drip accuracy, sand cleaning, mode of operation and so on are better than “Mars tank” . This article will be a brief introduction to the device, so that readers understand it.
