摘要
本文设计了一种靶式在线粘度计,通过对传统数显靶式流量计靶板受力原理的分析,将靶板改造成细管形靶芯。经改造后的靶式流量计,在测量流体流量的同时,可以实现对流体粘性力的检测。然后再通过设计的外接信号处理电路,将粘性力转换成粘度值显示。文中所设计的靶式在线粘度计可以实现对非牛顿流体粘度的精确在线测量。
An on-line viscometer is designed in this paper. First, the targets＇s force-principle？of the traditional digital？target flowmeter is analyzed. And then the target is changed into a target core based on the principle analysis. The changed target flowmeter can not noly measure the flow, but also measure viscous force. Finally, by signal processing circuit, the viscous force can be transformed into viscosity display. The designed target on-line viscometer can realize the on-line viscosity measurement of non-Newtonian fluid accurately.
