Title
(ZH) 用于测量管的共振频率的系统和方法
Abstract
(ZH)

本发明提出一种用于测量管的共振频率的系统。所述系统包括:振荡单元(21),其用于分别以多个振荡频率来振荡所述管;检测单元(22),其用于检测当所述管以每个振荡频率振荡时在将压力脉冲从所述管中的第一位置传输到第二位置的时间延迟,其中,在所述管以所述多个振荡频率的特定振荡频率范围中的每个振荡频率振荡时,所述检测单元(22)检测时间延迟的变化;确定单元(23),其用于确定当所述管以所述特定振荡频率范围中的振荡频率振荡时时间延迟的最大变化;以及指示单元(24),其用于将与所述时间延迟的最大变化对应的振荡频率指示为所述管的共振频率。
