摘要
深圳河口河工模型因占地面积较大,干、支流进口较多且位置分散,不仅给供水系统的布置带来很大困难,而且使得模型设备投资较大。为了解决经费不足带来的压力,要求模型所用流量计既要满足测量精度又要价格低廉。为此,在模型试验研究中首次采用了水表流量计(简称水表)。该水表是一种速度式仪表,具有起动流速低、测量范围宽、重复性好、结构简单、使用操作及维修方便且价格低廉等优点,并具有很好的性价比。水表安装使用时采取了相应的完善措施,经过试验运行表明,该水表满足河工模型试验中的测量要求,并取得了较好的应用效果。
Shenzhen river mouth model is characterized by occupying a larger area with six entrances of its branch rivers and their locations spreading, resulting in increasing the collocation difficulty of the water supply system and investment cost. In order to meet the requirements of both the accuracy and cost-saving of the meter used, an intelligent flow meter was first used in the river model test. This meter possesses the advantages of lower speed in starting, broader range in measurement, better repetition, simple structure, convenience in use and repair and cheap price, and its higher ratio of property to price. The result shows that the effect used is satisfactory and the requirement in test is fully reached.
