Patent number: 7747397Abstract: Described is 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 described is also an evaluation device for implementing the method as well as to a computer program and a computer program product for carrying out the method.Type: GrantFiled: December 20, 2007Date of Patent: June 29, 2010Assignee: Vega Grieshaber KGInventors: Roland Welle, Karl Griessbaum, Josef Fehrenbach, Thomas Deck, Martin Gaiser
