Abstract

In recent years, calibration demands of automatic monitoring stations for atmospheric radiation environment inChina are increasing. However, large flow samplers in monitoring stations are relatively large, so dismountingand transportation will result in significant cost. While the monitoring stations may be dozens or evenhundreds of kilometers apart and the cost of field testing is too high, so the values couldn’t be guaranteed. Inthis paper, a set of remote calibration device for large flow samplers based on master meter method is developed, which is a fully automated calibration system. Sealing test and mutual verification test of double master meters are designed. Besides, an intelligent video recognition system, a control terminal of field tests and a remote monitoring platform are built to fully guarantee authenticity and effectiveness of remote data. Key Words: remote calibration, large flow samplers, master meter method, intelligent video recognition system, control terminal of field tests, remote monitoring platform
