摘    要：为解决部分控制系统软件中需要自编公式进行气体流量温压补偿的问题,结合现场需要,作者对差压变送器开方和线性两种输出方式下,普通气体和蒸汽两种常用介质的软件温压补偿公式分别进行了推导,并举例说明公式在软件中的配置应用方法。为自动化软件开发人员进行气体流量温压补偿提供了实用方案。

Abstract: To solve temperature and pressure compensation problem of gas flow in some control system software,according to need of field,applied software temperature and pressure compensation formula for two output modes of square root and linear in common gas and steam were derived respectively.Configuration and application method of the formula in software is illustrated with examples.It provides a practical solution of gas flow temperature and pressure compensation for automation software developer.
