资料介绍

涡街流量计是根据涡街原理制备的测量气体和液体流量计量仪器,自上世纪八十年代以来被广泛使用,其技术也不断进步。本文就涡街流量计的旋涡发生体(阻流体)、检测元件(传感器)、前置放大器、滤波整形电路、D/A转换电路、输出接口电路等方面的技术特点和研究进展进行了综述,通过对涡街流量计原理的进一步的了解,期待有更好的改进思路,推动涡街流量计技术的进步。

The vortex flow-meter is a kind of measurement equipment for gas and liquid by the vortex principle.Since 1980 s,it has been gradually developed at quantity and range of application with its technological progress. The technological characteristics and research progress on the vortex flow-meter involved vortex generator( flow barrier),detecting element( sensor),preamplifier,filter shaping circuit,D/A conversion circuit and output interface circuit were summarized. By means of a better understanding about vortex flowmeter structure,the better improvement ideas of the vortex flowmeter were looked forward to meet and promote the technology to a high level.
