摘　　要：对GB1 2 36- 85圆弧型集流器改用为ISO 580 1文同位置处的流量压差数据进行了测试比较 ,并将其折算为流量系数 ,两者最大误差不超过 0 2 5%。The feasibility about the inlet quadrant nozzle for GB1236-85 substituted by the ISO 5801 Venturi nozzle has been analyzed and a contrastive experimentation has been done. On the basic of analyzing the geometric characteristics that are similar for the two types, conclusions has been got that the flowmeter differential pressures of the two types are similar at the different positions when converting them into flow coefficient and that the errors between them are no more than 0 25%.
