摘　　要：根据“十三五”发展规划提出的环保系统辐射环境自动监测站建设的配置标准,针对目前自动站中超大流量采样器计量精度较低的现状,本文应用高精度气体涡轮流量传感器和温度、压力补偿方法,设计了基于电池供电的空气采样器现场标定装置,该装置核准的计量精度为1%,装置在杭州丁桥站和上海监测站,其测试结果表明,可以提高自动站超大采样器的计量精度。According to the 13th Five-Year-Plan,the allocation standard of automatic radiation environmental monitoring station for environmental protection system.A high-precision gas turbine flow sensor and temperature and pressure compensation method are used to design this on-site calibration device for air samplers based on battery power supply.The calibration accuracy of the device is 1%.The test results of the device at Dingqiao Station in Hangzhou and Shanghai Monitoring Station show that the measurement accuracy of the super-large sampler can be improved.
