Patent number: 9395228Abstract: A device for measuring the level of a liquid within a container, in particular the level of liquid gas, comprises a housing and a piezoelectric element adapted for generating vibrations when energized. A coupling pad is provided which is bonded to the piezoelectric element for transmitting the vibrations to a surface of the container. Further, a non-tilting element is provided which surrounds the coupling pad. A method for measuring the level of liquid within a container uses a piezoelectric element for generating vibrations which are transmitted into the shell of the container. An analyzing strategy is used which distinguishes between normal post-pulse oscillations of the piezoelectric element after a measurement was triggered, and extended post-pulse oscillations which are the result of echoed oscillations in the shell of the container.Type: GrantFiled: February 15, 2013Date of Patent: July 19, 2016Assignee: Truma Geraetetechnik GmbH & Co. KGInventors: Thomas Molitor, Frank Ibach
