【摘要】 采用实验研究的方式，讨论了用同等级的流量仪表作为标准表检定其它流量计的可能性与可行性，提出了等精度传递的概念，分析了等精度传递系统中影响传递精度的因素。试验表明，只要仪表具有足够好的重复性，用其作为传递标准组建标准表法流量标准装置，可以使装置的准确度接近上一级流量标准的准确度。更多还原

【Abstract】 With the method of experimental study the possibility and feasibility of using the equal-graded flowmeter as the standard to cali- brate the other flowmeters is discussed and the equal-grad- ed accuracy transfer is stated. The factors which are affecting the ac- transfer in such are analyzed. The experiments show that if the instrument features good repeatability then the actual accu- racy of the standard device using this instrument will reach the higher graded accuracy.更多还原
