一、概述标准表法测量流量计依据JJG1029-2007《涡街流量计检定规程》,在检定过程中,将流量分别调到规程要求的流量值,运行至流体状态稳定。计算机同步采集相应量值并进行数据处理,直接输出被检流量计的平均仪表系数K和相对误差E及重复性Er。本次试验是在温度为23℃、湿度为50%RH、大气压力为100.123k Pa的环境下进行的。气体流量标准装置主要由流量标准器、试验管路、流体发生源、计时器、控制设备及数据合成采 First, an overview of the standard meter measuring flowmeter According to JJG1029-2007 “vortex flowmeter verification procedures” in the verification process, the flow were transferred to the requirements of the process flow values, running to the fluid state is stable. The computer collects the corresponding values ​​synchronously and processes the data, directly outputs the average meter factor K and relative error E and repeatability Er of the seized flow meter. This test was carried out under the conditions of a temperature of 23 ° C, a humidity of 50% RH and an atmospheric pressure of 100.123 kPa. Gas flow standard device mainly by the flow standard, test pipeline, fluid source, timer, control equipment and data synthesis
