Abstract
Aiming at the problem that rotating current meters and method floats are still used in discharge measurement of most middle and small rivers and ADCP can’t be tested when there are flood or floater, the article proposes using radar wave velocity apparatus at discharge measurement of middle and small creeks. Radar wave current meters have many kinds, such as wireless remote control radar wave digital flow measurement, online remote control multi-probe radar wave flow measurement, cableway radar wave flow equipment and hand radio wave current meter. “Wireless remote control radar wave digital flow measurement” is new. The article analyzes the principle of test and performance characteristics in detail. It is exhaustively tested in hydrometric stations of Shanxi Province, the Middle Innings of Yellow River, Hunan Changde and Zhangjiajie. By many tests of different rivers and environment, the parameters of the test results are complete and can be entered into database directly. All indications meet the requirement of《Hydrological test standard》. Construction and installation is convenient. It can be put into use at any time. And the data can be tested in the shortest time. It can be the main measurement tools of flow automatic test in middle and small creeks.关键词
