在这项工作中，一种新的在线非侵入式流变测量技术的开发和测试中试工厂和工业规模的应用。该方法是基于超声脉冲回波多普勒技术（UVP）和压差法（PD）的组合。流变流动特性来自于同时记录和在线分析的速度分布在管通道和相关的径向剪切应力分布计算从压力损失沿着流动通道。结果表明，在线UVP-PD技术允许非侵入性的非透明和高浓度悬浮液的流变流动行为表征。
In this work a novel in-line non-invasive rheological measuring technique is developed and tested in pilot plant and industrial-scale applications. The method is based on a combination of the ultrasonic pulsed echo Doppler technique (UVP) and pressure difference method (PD). The rheological flow properties are derived from simultaneous recording and on-line analysis of the velocity profiles across the tube channel and related radial shear stress profiles calculated from the pressure loss along the flow channel. It is shown that the in-line UVP-PD technique allows for the non-invasive rheological flow behaviour characterization of non-transparent and highly concentrated suspensions.
