The Design Of Oil Tank Cars Capacity Verification System

The origin of this paper is from measurement institute of science and technology in Anhui province, which focuses on research and production of oil tank vehicle's capacity verification system.Author summarized foreign and state reference and national standards, made deep and comprehensive research on master meter and geometric metrology method. According contribution in institute, and with the design requirements in JJG 133-2005 Oil Tanker Capacity, finished the design on a standard test table of tanker, The research involved testing device's temperature, pressure, liquid level volume measurement and selection of equipment which can complete design.With designed reasonably pipeline, the experimental results show that fixed-point electromagnetic flow meter measurement repeatability can be achieved 0.05%. Analysis of the composition of system error, the error transfer coefficient is derived and constitutes a systematic error of the experimental test. Synthesis error can meet the international requirements. The author has prepared verification system measurement software. Achieve flow control, human-computer interface, computer automated data acquisition, data processing functions of the verification system.The study in this paper will lay the foundation for set up verification system and improve test accuracy. The study of oil tanker volume verification system base on master meter method not only broadens the scope of application of master meter method, but also lays the theoretical and experimental foundation for the follow-up study of this topic.
