    Abstract: Bei einer Ultraschall-Niveausensorvorrichtung ist vorgesehen, einen Ultraschallwandler (2) an einem Tauchrohr oder Tauchstab (7) anzuordnen und unmittelbar von oben in eine Flüssigkeit (4) in einem Behälter (1) einzuführen. Der Ultraschallwandler (2) sendet dann Ultraschallsignale (3) zu einem Reflektor (9) und einer Flüssigkeitsgrenzfläche (5) und empfängt daraufhin zunächst ein Reflexionssignal (10) vom Reflektor (9) und anschliessend ein Reflexionssignal (6) von der Flüssigkeitsgrenzfläche (5). Auf diese Weise ist die Messung selbstkalibrierend und die Vorrichtung eigensicher im Sinne des Explosionsschutzes ausgelegt; darüber hinaus misst die U.Itraschall-Niveausensorvorrichtung auch dann noch richtig, wenn sich ein Schaum (18) auf der Oberfläche der Flüssigkeit (4) ausgebildet hat.

    Abstract: A system for determining the depth of a fluid in a storage tank. The depth of the fluid is determined after the detection of a pulsed wave that is reflected from the top surface of the fluid. The system includes a transducer, an analog-to-digital converter, and a filter. The transducer is configured to sense the reflected pulsed wave and to generate an analog input signal that corresponds to the reflected pulsed wave. The analog-to-digital converter is coupled to the transducer, and configured to convert the analog input signal into a digital input signal. The filter is coupled to the analog-to-digital converter. The filter includes a finite impulse response filter that is configured to receive the digital input signal and to generate a digital output signal.

    Abstract: The present invention relates to a device (10) for providing a gas composition compensated acoustic measurement of the level of a liquid (16) in a tank (18). The device comprises a transducer (14) arranged outside said liquid for transmitting and receiving acoustic signals, and a waveguide (12) connected to said transducer and extending into the liquid. The device further comprises means for feeding a flow of fluid from said tank into the part of said waveguide which is located above the liquid level. That results in that the gas composition become essentially similar throughout the whole of the waveguide located above the liquid level, whereby the level measurement using the speed of sound in the waveguide, which speed is dependant on gas composition, becomes very accurate.

    Abstract: Das erfindungsgemässe Verfahren erlaubt insbesondere auch eine Extrapolation des Messwerts am oberen und unteren Ende des Messbereichs, wo in der Regel keine direkte Messung möglich ist durch die Überlagerung von Störsignalen, etwa durch Reflektionen an einer Radar-Antenne. Bei starken Störsignalen, etwa durch Eigenresonanzen des Behälters oder eines Stutzens, in den das Messgerät eingebaut ist, kann immer dann das direkte Füllstandssignal verwendet werden, wenn es durch Überlagerung mit einem Störsignal in der Amplitude gross und damit detektierbar wird, während dann, wenn es zwischen zwei Störsignalen liegt und nicht über diese hinausragt, mit der Verschiebung des Signals von der Reflektionsstelle ein Füllstandswert interpoliert werden kann. Das Verfahren adaptiert sich auch selbständig an eine vorliegende Messsituation, während bei bisher bekannten Verfahren vom Bediener zwischen der Messung über eine Verschiebung des EOL-Signals oder einer Messung über das direkte Füllstandsecho entschieden werden muss.

    Abstract: Apparatus for monitoring the composition of a medium comprises an elongated member for insertion into said medium. An array of transmitters and receivers of ultrasonic waves is disposed at intervals along at least part of the length of the member, and reflector means provided to reflect transmitted ultrasonic waves to the receivers. The reflector means is supported by, but laterally spaced from, said member so that the medium occupies the space between said elongated member and the reflector means so that transmitted ultrasonic waves pass through said medium en route to the receivers. Monitoring means are provided to give a signal dependent upon the time taken for an ultrasonic sound wave to travel from a transmitter to a receiver associated therewith.

    Abstract: Embodiments of the invention are described including a remote level monitoring device. The remote level monitoring device includes a ping source for placement on a tank containing a liquid. The ping source provides a ping signal that is transmitted into the tank. In a preferred embodiment, the ping signal is an ultrasonic signal. A transducer is provided for receiving reflections of the ping signal off of the top surface of the liquid. The difference between the time the ping is sent and the time it is received indicates the top level of the liquid in the tank. A signal indicating the level is transmitted to a central monitoring facility. Preferably, the signal is transmitted via a communications satellite. Refilling trucks are then sent to the remote site to refill the tank when the level signal indicates that refilling is necessary.
