A fill level monitoring device (100) for monitoring a fill level (210) of a fluid in a container (200) comprises an exciter (10), a sensor (20), a signal source (30) connected to the exciter (10), a processor (40), at least one spatial orientation and acceleration sensor (60), and a fill level indicator (50). An apparatus (100) couples a vibratory load having a plurality of frequency components into a container (200) using a signal source (30) and an exciter (10). The sensor (20) measures vibrations in the container (200) after the exciter (10) transmits the vibration load into the container (200). The processor (40) performs a spectral analysis of the input signal (31) and the vibration signal (21) from the sensor (20) to compare these respective spectral functions to extract a resonant frequency of the container (200), the resonant frequency being based on the spatial orientation of the container (200). A fill level indicator (50) calculates a current fill level (210) of the container (200) from the extracted resonance frequency and the spatial orientation signal from the spatial orientation sensor (60) by associating the collected data with reference data.

    一种用于监测容器(200)中的流体的填充液位(210)的填充液位监测装置(100),包括激励器(10)、传感器(20)、连接至激励器(10)的信号源(30)、处理器(40)、至少一个空间取向和加速度传感器(60)以及填充液位指示器(50)。装置(100)使用信号源(30)和激励器(10)将具有多个频率分量的振动载荷耦合到容器(200)中。传感器(20)在激励器(10)将振动载荷传递到容器(200)中之后测量容器(200)中的振动。处理器(40)执行输入信号(31)和来自传感器(20)的振动信号(21)的频谱分析,从而比较这些相应的频谱函数以提取容器(200)的共振频率,共振频率基于容器(200)的空间取向。填充液位指示器(50)通过使收集的数据与参考数据相关联来根据所提取的共振频率和来自空间取向传感器(60)的空间取向信号计算容器(200)的当前的填充液位(210)。
