    • The present invention relates to a method for automatically initiating an update of a parasitic echo storage device in a fill level meter operating according to a runtime method. In this method individual echoes of echo curves of different ages are allocated, according to their typical echo characteristics, to global echo groups so that subsequently, after examining the behaviour over time of the echoes of the respective global echo curves, it can be judged whether the echoes of the respective global echo curves are useful echoes or parasitic echoes. Starting from this classification, the parasitic echo storage device is then updated with the oldest echoes of the corresponding global echo groups. Apart from the method for updating a parasitic echo storage device, the invention also relates to an evaluation device for implementing the method according to the invention, as well as to a computer program and a computer program product for carrying out the method.
    • 本发明涉及一种在根据运行时方法操作的填充液位计中自动启动寄生回波存储装置更新的方法。 在这种方法中,根据其典型的回波特征将不同年龄的回波曲线的各个回波分配给全局回波组,从而随后在检查各个全局回波曲线的回波随时间的行为后,可以判断是否 各个全局回波曲线的回波是有用的回波或寄生回波。 从该分类开始,然后用对应的全局回波组的最旧的回波更新寄生回波存储装置。 除了更新寄生回波存储装置的方法之外,本发明还涉及用于实现根据本发明的方法的评估装置以及用于执行该方法的计算机程序和计算机程序产品。
