    Abstract: 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.

    Abstract: A system for estimating a flowable substrate level in a storage unit is disclosed. In one embodiment, the system includes a transmitter and a conductor that extend downwardly into a grain storage bin, which cycles through a range of frequencies in order to determine the resonant frequency of the conductor which changes depending on the amount of grain in the bin.

    Abstract: A liquid storage device includes: a liquid storage having a storage chamber for storing liquid; first communication devices each for transmitting a radio wave for carrying out short distance wireless communication; a second communication device for receiving the radio wave transmitted from each first communication device; and a controller. The first communication devices are arranged in a configuration corresponding to a direction of movement of a boundary surface between a liquid stored area and a liquid non-stored area in the storage chamber. The movement is caused by increase or decrease of an amount of the liquid in the storage chamber. The storage chamber is partly interposed between the second communication device and the first communication devices. The controller detects a position of the boundary surface based on a reception status of the radio wave transmitted from each first communication device and received by the second communication device.

    Abstract: A model is based on noise-suppression technique in level indicators that uses mutually independent mathematical models, the quality of each of which models is calculated by comparing with measured values. The models are then weighted and combined, or a single model is selected, in order to calculate the level at a later point in time. Effective noise suppression may be achieved by these means.
