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). |
