基于S3C44B0X智能补偿式流量积算仪

摘要

A natural gas flow totalizer based on S3C44B0X was designed in need of accuracy of natural gas measurement in practice. Using the gas compression factor Z, to revise ideal gas status equation which could more accurately achieve the temperature and pressure compensation of natural gas real time. The design of hardware and software of the system were introduced in detail. The application shows that this system runs accurately and stably. The technology and methods adopted in the system are practical and worthy using widely. [Ch,3 fig. 10 ref. ]%为解决天然气计量中的准确性问题,设计基于S3C44B0X为核心的天然气流量积算仪,引入天然气压缩系数Z,对理想气体状态方程进行修正,使流量积算仪能够更精确地进行实时温压补偿;该系统详细介绍了积算仪的硬件和软件设计方案,应用结果表明,该系统检测精度高,运行稳定可靠,具有一定的实用性和推广价值.
