【摘要】 热计量仪表中各组成部分的准确度对其热量计量准确度起着至关重要的作用。目前的有关标准与规程只给出了热计量仪表误差极限的计算方法 ,并由此确定其准确度等级。实际上 ,热计量仪表的误差并不是其各部分组件误差的代数和。文中根据热计量仪表误差计算的基本方法 ,提出了一种计算热计量仪表准确度的简化法 ,具有一定的准确性 ,便于在实际测量中使用更多还原

【Abstract】 The accuracy of components in heat meter has fateful effect on its measuring accuracy. The calculation method of error limit is given in actual product standards and testing specifications of heat meter. The accuracy grade of heat meters will be determined by it. Actually, the accuracy of heat meter is not the sum of the component accuracies. Based on the basic accuracy calculation method of heat meter, a simple accuracy calculation method of heat meters is proposed. It has sufficient veracity and can be used in practice measurement conveniently.更多还原
