Application and Analysis of Acoustic Time-of-Flight Method in Tidal River Sections
摘要
Abstract
Online flow monitoring in tidal river sections has always been a challenge in hydrological monitoring,requiring high standards for water level measurement data.The acoustic full-cross-section time-of-flight flow measurement system addresses this issue by measuring the laminar velocity across the entire horizontal cross-section and correlating it with the average cross-sectional velocity to obtain accurate cross-sectional flow rates.This method is suitable for turbulent flow conditions and bidirectional flows(both positive and negative)characteristic of tidal river sections.The application of this system at the Guangchen station meets the accuracy requirements of Class Ⅱ hydrological stations,satisfies the needs for hydrological measurement data,and the measured flow can be used as actual flow data.The research conclusions provide a solution approach and practical guidance for online hydrological monitoring in tidal river sections.关键词
