一、引言计量标准的不确定度是衡量计量检定/校准工作可靠性的重要指标,也是衡量被检器具溯源结果的主要依据。凝胶流量计标准装置采用凝胶水基模拟液作为工作介质,主要用于凝胶发动机用质量流量计(以下简称“凝胶流量计”)的测试和量值传递。本装置是为了模拟凝胶流量计的实际使用工况,实现凝胶流量计的实流模拟校准建立的一套液体流量标准装置。为了确保流量测量的准确度,
I. INTRODUCTION The uncertainty of metrological standards is an important index to measure the reliability of metrological verification / calibration work. It is also the main basis for measuring the traceability of the inspected instruments. Gel flow meter standard device using gel water-based simulation liquid as the working medium, mainly for the gel engine mass flow meter (hereinafter referred to as “gel flow meter ”) test and the value of transmission. This device is to simulate the actual use of gel flowmeter conditions, to achieve real-time gel flowmeter analog calibration established a set of standard liquid flow device. In order to ensure the accuracy of the flow measurement,
