摘　　要：提出了用同等级的流量仪表作为流量传递标准检定其它流量计的流量量值等精度传递系统 ,分析了等精度传递系统中影响传递准确度的各种因素。并用实验研究的方式对等精度传递系统的综合性能进行评价 ,试验表明 :只要流量仪表具有足够好的重复性 。The equal-graded accuracy dissemination system for flow value of quantity using the equalgraded flowmeter as a standard to calibrate the other flowmeters is presented in the paper. The factors that influence the dissemination accuracy in such system are analyzed and the general features of the system are evaluated with the method of experimental study. The experimental results show that if the instrument features have good repeatability then the actual accuracy of the flow standard facilities with standard meter method using them will approach or reach the accuracy of the higher graded standards.
