Maximum permissible error of heat meter in operation摘要分析了热量表的误差组成及影响误差的因素，并模拟计算了实际不同运行工况下热量表的最大误差，得出结论；当散热器进出水温差t达到最小值、流量q达到最小允许值时，热表误差限的最大值为10%，随流量的增加，误差限逐渐降为8%；t不变时，流量较小误差较小；q不变时，t越大，误差越小，当t3t min时，误差接近常数；一定温差下，当实际流量大于常用流量的一半后，误差近似为常数。关键词：热量表/最大允许误差/供热计量收费AbstractAnalyses the constitution of the heat meter measurement error and its affecting factors， calculates the maximal measurement error of a heat meter under the different operation conditions. Concludes that the maximal meas
