直位移磁浮子流量计测量方法的探究

Explore on the Direct Displacement Magnetic Float Flowmeter Measurement

浮子流量计的浮子位移与流量之间对应着明确的函数关系,测出浮子的位移即可确定流量的大小。传统的浮子流量计的测量方法为角位移式测量,直位移测量式是在角位移测量式的基础之上而诞生的又一种测量方式,这种测量方式完全去掉了耦合磁钢、测量磁钢。它应用在小流量的测量中,比起角位移测量方式节约了成本,简化了结构。本文介绍了基于霍尔元件的直位移式磁浮子流量计的测量原理、方法,采集信号的处理、运算法则,实验数据及结果。

There are specific function relationships between the amount of flows and displacements of floater. We obtain the exact flows through measuring the floater displacements. The angular displacement is adopted traditionally, and the direct displacement is,a kind of new measurement based on the angular displacement, which has eliminated the coupling magnetic steel and measuring magnetic steel. Compared to the angular measurement, this method simplifies device structure and saves the expenses. This article introduces the measure methods and principles of direct displacement magnetic float flow meter, particularly in signal process, algorithm, experiment statistics and results.
