摘　　要：设计了基于多电导式流速测量传感器的河流流速测量系统。系统包括多电导式流速测量传感器、滤波调理电路、现场可编程门阵列(FPGA)及显示器。经试验验证:该系统对河流流速测量误差小于4%,表明该系统测量准确。利用该系统测量出河流过水断面上不同深度点的流速和该点河流相应部分的断面面积相乘可计算出该部分流量,不同深度流量的和即为全断面的流量。A river flow velocity measurement system based on multi-conductance flow velocity measurement sensor is designed.The system consists of a multi-conductance velocity measurement sensor,a filtering and conditioning circuit,a field programmable gate array(FPGA)and a display.The experimental results show that the measurement error of the system is less than 4%,which indicates that the system is accurate and reliable.The system can be used to measure the flow velocity at different depth points on the river cross-section and multiply the cross-section area of the corresponding part of the river to calculate flow of the part.The sum of the flow volume at different depth is the flow of the whole section.
