流量和热量计量是供热管网和供热站长期存在的一个难题。唐山工程技术学院研制的国家专利产品“ＺＬＲＪ－Ｉ型智能流量热量积算仪”，很好地解决了这一问题。本文介绍此积算仪所用的工业标准弯头弯管流量计的部分常温实验。在实验研究的基础上，重点介绍了这种流量计的一致性实验结果和统计分析情况，说明了该弯头作为流量传感器的可行性。 Flow and heat metering are long-standing problems for heating networks and heating plants. Tangshan Institute of Technology developed a national patent product “ZLRJ-I intelligent flow calorimeter,” a good solution to this problem. This article describes some of the industry standard elbow flow meters used in this calculator. Based on the experimental study, the consistency of experimental results and statistical analysis of the flowmeter are introduced emphatically, and the feasibility of the elbow as the flow sensor is demonstrated.
