摘　　要：针对目前在流量计生产制造中大量需要对气体流量计进行检定,为使检定结果高效、精确,在建立气体流量模型基础上,设计了标准表法气体流量检定装置的系统结构与构造,利用MATLAB实现了流量控制策略运算及仿真调试,采用OPC技术在组态王和King ACT软件之间实现了气体流量校准系统的数据采集的自动处理、在线检定、实时曲线查询,保证了检定过程自动化和高效性。对实验数据进行误差和不确定度计算分析,结果符合工业要求。At present there are a lot of works on gas flow meter calibration in production manufacture. The structure and compose of master meter calibration system with gas flow standard device were designed based on the gas flow model in order to test with efficient and accurate results. The flow control algorithm and simulation debugging were achieved by MATLAB. And the gas flow calibration system could be completed of automatic data acquisition,on-line verification,and real- time curve inquiry between Kingview and King ACT with using OPC technology. The verification process was ensured with automation and high efficiency. The experimental data is error and uncertainty analyzed,which results meet industrial requirements.
