1、河北大学硕士学位论文移动式气体流量标准装置的研制姓名:赵宁申请学位级别:硕士专业:测试计量技术及仪器指导教师:刘辰魁;李金海20100501摘要摘要流量标准装置就是用来复现流量量值,最终溯源到国家基本量基准的实验装置。其主要作用就是对流量计进行检定和校准,确保流量量值的统一和准确可靠。由于实验室计量检定的局限性,本文设计了移动式气体流量标准装置,作为实验室标准装置的补充,实现了对无法送检气体流量计的现场检测。整套装置自动化程度高,数据显示实时化,检测手段智能化;针对现场检测这一特点,本装置加装了现场环境监测系统,对检测现场环境温度、大气压
2、力等数据进行实时采集,并在最终数据处理时参与补偿计算,从而使整套装置在整个计量过程中的准确性、快速性、可靠性等方面得到了很好的保证。本文从市场调研到课题的提出,从设计思想和基本工作原理的确立到硬件设计、软件设计,都进行的详尽的阐述。经过近一年的努力,样机试制成功。本装置运行时性能稳定、操作简便、性价比高、测量精度和测量重复性均达到了设计要求;软件界面直观,人机交互性好。通过近三个月的实验调试,各项技术指标均能达到设计要求,满足计量检定校准工作的需要。关键词气体流量标准装置自动检定系统补偿系统IAbstractAbstractFlowsta
