摘要
作为环境保护的一个重要方面,排放污水的准确计量一直存在着成本高、精度低的问题。自主研发、改进了一种板式流量智能传感器,介绍了其系统的原理,硬件设计及软件结构。通过实验室巴歇尔槽的流量检测实验测得的数据进行比较,得到改进的板式流量计的平均误差为1.76%,大大减小了改进前的误差,实现了高精度、低成本的要求,具有广阔的市场应用前景。
As an important aspect of environmental protection, there has been a problem of high cost and low accuracy for the accurate measurement of sewage discharge. A kind of improved slab intelligent sensor for flow measurement is researched and developed independently. Principle of system, hardware design and software structure is introduced. Through compared datas of the flow testing experiment of the Parshall flume in the laboratory, average error of the improved sensor is 1.76 %, which greatly reduces the error of the old one, the sensor meets requirements of high precise and low cost, and has broad application prospect in market.
