摘　　要：在系统分析涡街流量计所具有优点的基础上,具体阐述了涡街流量计的耐振性能等。同时也指出了它所存在的缺点,并相应地给出其新的改进,指出在选择合适的流量计时应扬其所长,避其所短。为流量计的选型提供了可靠的参考价值。On the basis of the analysis on the merits of vortex flowmeter, the performance of anti-vibration is described concretely. Meanwhile, the disadvantages of the flowmeter are also pointed out, and the relative improvement to these disadvantages is proposed. For selecting proper flowmeter to application, we shall maximize favorable factors and minimize unfavorable ones. The paper is a good reference to model selection of flowmeters.
