Procedure to measure the level (14) of a liquid (13) by means of elastic waves, such liquid (13) being contained within an axially moving tube (11) and cooperating with a filler tube (12), the filler tube (12) being used as an element in the transmission of elastic waves to the liquid (13), such elastic waves being picked up (16) outside the axially moving tube (11). Device (10) to carry out the above procedure, which device (10) cooperates with a filler tube (12) and comprises: at least one transducer (15) to transmit energization of the vibration of the filler tube (12), and at least one receiver transducer (16) located outside the axially moving tube (11).

A method of measuring the level of a liquid comprising the steps of filling a moving, generally tubular, container through a liquid filler tube while the container moves relative to the filler tube, maintaining at least a portion of the filler tube immersed in the liquid within the tubular container

A method of measuring the level of a liquid comprising the steps of filling a moving, generally tubular, container through a liquid filler tube while the container moves relative to the filler tube, maintaining at least a portion of the filler tube immersed in the liquid within the tubular container, creating energy waves in the filler tube which are transmitted to the liquid in the tubular container, detecting the transmitted energy waves, and converting the detected energy waves into an indication of the liquid level of the liquid in the tubular container. A device for measuring the level of a liquid comprising filler tube means for introducing liquid into a generally tubular container during movement of the container relative to the filler tube means while maintaining at least a portion of the filler tube means immersed in a liquid, means for creating energy waves in the filler tube means which are transmitted therethrough to the liquid in the tubular container and to the tubular container, means for detecting the transmitted energy waves, and means for converting the detected energy waves into an indication of the liquid level of the liquid in the tubular container.
