摘要
通过对多种液位检测技术对比分析 ,提出一种利用超声波技术由储罐底部直接测量的方法 ,介绍了基于该方法的测量原理和仪器实现。此方法能够较好解决分界面明显的液位检测问题 ,但是对于一些气 -液界面模糊的介质的液位检测存在一定的问题 。
By the contrast and analysis of several techniques on measuring liquid-level, this paper introduces a method that uses ultrasonic technique to measure liquid-level directly from the bottom of pot, and presents the principle of measurement and the design of instrument. This method can measure the propellant level when the interface is clear, but happen some questions when the interface is faint. This paper analyzes the latter and brings some feasible suggestion for it.
