摘　　要：河流流量和流速测量是水利测量的基础工作,然而设计测量精确而又使用方便的仪器比较困难。本文改进了部分面积法,适用于河流流量测量仪器的设计;介绍了采用单片机开发的便携式流量计算仪,提出该装置的硬件原理和组成,并讨论用于实现信号采集、流速和流量处理的软件设计方法。经实验验证本装置具有实用价值。The measurement of flow quantity and velocity is the primary task of hydrological measurement, whereas it is much hard to design a meter with high precision and convenient usage. In this article, partial area method is improved to adapt to designing of meter, the hardware structure of portable flow quantity calculator developed with MCU is introduced, and software module of signal collecting, and velocity and quantity processing is presented and discussed. It is validated that the calculator is provided with practicality.
