System and method for real time remote measurement of geometric parameters of a pipeline in the launch step, through sound waves

A system for real time remote measurement, through sound waves, of geometric parameters of a pipeline in the launch step is described. System comprises an acoustic transceiver unit which can be positioned in pipeline , and a control unit. The acoustic transceiver comprises an acoustic transmission configured to emit an input acoustic signal sa1 into pipeline 2, based on an electric pilot signal sp; and further comprises an acoustic receiving unit 5, distinct from the acoustic transmission unit 4, configured to detect the input acoustic signal sa1 and to generate a first electric measurement signal se1, dependent on the input acoustic signal sa1 The acoustic receiving unit 5 is further configured to receive an input return signal sa2, generated in pipeline 2 and dependent on the input acoustic signal sa1 and on the geometric parameters of pipeline 2, and to generate a second electric measurement signal se2 based on the return acoustic signal sa2. The control unit 3 is configured to generate the electric pilot signal sp and is operatively connected to the acoustic transceiver unit 1 to provide the electric pilot signal sp and to receive the first electric measurement signal se1 and the second electric measurement signal se2. Furthermore, the control unit 3 is configured to measure the geometric parameters of pipeline 2 based on the first and second electric measurement signals (se1, se2 ). A method for real time remote measurement, through sound waves, of geometric parameters of a pipeline 2 in the launch step is further described, which can be carried out by the aforesaid system 100
