vortex precession flowmeter meaning in Chinese
旋进流量计
旋涡进动流量计
旋涡流量计
Examples
- Vortex precession flowmeter
旋涡进动流量计 - There are two kinds of vortex type oscillatory flowmeter : vortex flowmeter and vortex precession flowmeter
基于旋涡流体振荡原理的流量计主要有两种：涡街流量计和旋进旋涡流量计。 - The technique of fluid mechanics simulation and the technique of modern fluid mechanics experiment were applied to research on the fluid oscillation characteristics of vortex flowmeter and vortex precession flowmeter
以流场仿真技术和实验流体力学的相结合的方法，系统地研究了旋涡型流体振动流量计的流体振动特性。 - In this work , a new dual triangulate bluff body vortex flowmeter was developed , the flux lower limit value of which lower by 50 % that of the old single bluff body vortex flowmeter . the linear correlation of the correlation between the velocity pressures of fluid disturbs wave and that of vortex precession in vortex precession flowmeter was brought to light , and a spectrum phase discrimination method based on fft to remove the effect of fluid pulsating interference on vortex precession flowmeter was advanced
研制出比传统单钝体涡街流量计流量下限降低约50的新型双钝体涡街流量计；揭示出脉动流中旋进旋涡流量计流体振动特性，并在此基础上提出基于fft相位判别的数字信号处理方法来消除流场脉动对旋进旋涡流量计的干扰的方法。
