摘　　要：随着我国天然气工业的发展,已有大量超声波流量计用于高压、大流量的天然气计量。尽管我国已于2001年颁布并实施了气体超声波流量计使用方面的国家标准GB/T18604-2001,但是随着超声波流量计越来越广泛的使用,国内外对超声波流量计计量性能的影响因素已有了进一步的研究;而且,目前我国超声波流量计在天然气计量中的应用效果也还需要进一步改善。因此,根据目前国、内外最新研究成果,对噪声、脏污、压力及温度测量对超声波流量计计量系统性能的主要影响因素以及控制对策进行了分析探讨,以期改变虽经实验室检定合格、但用于现场却不能达到预期计量性能效果的情况,使超声波流量计在现场能够得到更好的应用。A lot of ultrasonic flowmeters have been used in high-pressure, large-flow rate natural gas metering, as the development of Chinese natural gas industry. Although China issued and implement the national criterion of GB/T18604-2001 on the application of nature gas ultrasonic flowmeters, there are further international researches on factors which have impacts on measurement performance of ultrasonic meter as its wide applications. Moreover, application efficiency of ultrasonic flowmeter needs to be improved in China. So further studies need to be conducted on international latest researches, main factors which influence ultrasonic flowmeters' performance as a result of measurement of noises, smudgy, pressure and temperature, and the related solutions, to improve the practical function of ultrasonic flowmeter making it be efficient not only in laboratory test but also in on-site applications.
