灌区渠道水流流速的监测需要先进的测流仪器。声学多普勒测速仪测流装置,它不破坏流场、响应速度快、测量精度高,由于其方便、快速和精确的流速测量特点,应用范围起来越广泛。文章对比了传统流速仪和声学多普勒水流仪的适用条件,介绍了声学多普勒水流仪的基本原理,为灌区水利用系数和灌区的量水工作提供了一种新的测流装置和方法。
Irrigation channel flow velocity monitoring needs advanced flow measurement equipment. Acoustic Doppler velocimetry device, it does not damage the flow field, fast response, high accuracy, due to its convenient, fast and accurate measurement of flow characteristics, the more extensive range of applications. The article compares the application conditions of traditional anemometer and acoustic Doppler flowmeter, introduces the basic principle of acoustic Doppler flowmeter, provides a new flow measurement device for water utilization coefficient and irrigation water volume in irrigation district, method.
