WANG Jian sheng, WANG Chen jian, CHEN Zhan xiu (Dept. of Thermal Energy Engineering, College of Mechanical Engineering, Tianjin University, Tianjin 300072,China)  
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.
