摘　　要：在实际应用中,燃油流量计常会工作于非稳定流量状态下,此时流量计的计量性能可能会发生变化。利用燃油动态流量标准装置,对科里奥利质量流量计和容积式刮板流量计分别进行非稳态流量试验,分析了非稳态流量环境对这两种流量计测量结果的影响,并给出了使用和校准建议。In practical applications, the fuel flowmeter will work in unsteady flow state, and the measurement performance of the flowmeter may change. Using the dynamic fuel flow standard device, the unsteady flow tests was performed on the Coriolis mass flowmeter and the volumetric scraper flowmeter. The influence of unsteady flow environment on the measurement results of the two kinds flowmeters is analyzed, and the use and calibration of recommendations are given.
