摘　　要：以DN 80 mm气体涡轮流量计为研究对象,对涡轮流量计在不同介质、不同压力下的流量计仪表系数进行实验研究,分析流量计计量性能。不同介质标定的仪表系数具有明显的差异性。为保证公平贸易,在同一计量系统中使用的流量计宜使用同一种介质进行标定。Taking the DN 80 mm gas turbine flowmeter as the research object,experimental research was conducted on the instrument coefficient of the turbine flowmeter under different media and pressures,and the metrological performance of the flowmeter was analyzed.The instrument coefficients calibrated with different media have significant differences.To ensure fair trade,flow meters used in the same measurement system should be calibrated using the same medium.

关 键 词：涡轮流量计标定 仪表系数 示值相对误差
