Combining the engineering examples, this paper introduces several practical flowmeasurement methods of contain impurity fluid, and only refers to automation instrument design and repair persons.
本文结合工程实例，介绍了几种实用的含杂质流体的流量测量方案，供自动化仪表设计及维护人员参考。

The average shear rate obtained with this method is a more reasonable measurementof the average shear history of fluid in turbulent pipe flow.
对于湍流，按本方法计算的平均剪切率能合理地度量流体的平均剪切历史。

In order to achieve a remote measurement for fluidflow, research was made on theoretic models and experimental measurement methods for transmission pressure wave of the horizontal pipeline.
