影响涡街流量计测量准确度的几个因素

Several Influence Factors to Vortex Flowmeter Accuracy

涡街流量计是生产中测量流量的重要工具之一。文章简述了涡街流量计的测量原理、基本结构,详细分析了影响涡街流量计测量准确度的选型、安装、温度压力补偿、旋涡发生体迎流面堆积、配管内径与流量计内径不一致等因素,并提出了解决影响测量精度的具体方案。

Vortex Flowmeter is one of the most important implements of flow measuring in industry. The measure principle and basic configuration of vortex flowmeterwas introduced in the paper. Then the causes which may affect the precision of flow measuring was analyzed, including products type selection, installation, temperature and pressure compensation, mating pipe diameter, and so on. Furthermore, the means which could resolve vortex flowmeter＇s measuring precision was explored.
