基于框架式流速仪法的明渠流量测量方法研究

Research on Open Channel Flow Measurement Method Based on Framework Flow Meter Method

框架式流速仪法是对传统流速仪法的优化和升级,通过合理布设一定数量的流速仪,配套专用采集计算系统,可以实现流速仪多点布置、同步测量、精准计算,确保断面流量实测精度可以达到2%,使框架式流速仪法作为可靠的基本测流方法运用于现场明渠测流和标定其它测流方法。

The framework flow meter method is an optimization and upgrade of the traditional flow meter method.Reasonably arranging a certain number of flow meters and supporting a dedicated collection and calculation system can achieve multi-point layout,synchronous measurement,and accurate calculation of flow meters,ensuring that the accuracy of cross-sectional flow measurement can reach 2%.The results show that the framework flow meter method is a reliable basic flow measurement method that can be applied to on-site open channel flow measurement and calibration of other flow measurement methods.
