冲击振动式物料位计原理与实验研究

The principle and experiment of a material level detection unit with impulse vibrations

一种全新的完全非接触料位测量方法。对容器外壁施加机械激励 ,并对容器外壁上所产生的机械波进行检测。通过特征分析、提取 ,得出内部物料界面的信息。全部测量装置都在容器外部 ,实现无污染、方便。

This paper gives an account of a brand new contactless way to measure a material level.Excited by mechanical impulses,a mechanical wave will spread on the wall of a vessel.With the signal processing of identification and analysis,we can get the information on the material level from the wall vibrations.Since the whole detection unit is located out of the vessel,it is an entirely contactless,clean,convenient and cheap way to measure the material level.
