Abstract: A system and method remotely measure in real time through sound waves, geometric parameters of a pipeline in the launch step. An acoustic transceiver positioned in a pipeline includes an acoustic transmitter emitting an input acoustic signal into the pipeline, based on an electric pilot signal. An acoustic receiver detects the input acoustic signal and generates a first electric measurement signal, dependent on the input acoustic signal. The acoustic receiver receives an input return signal dependent on the input acoustic signal and on pipeline geometric parameters, and generates a second electric measurement signal based on the return acoustic signal. A control unit generates an electric pilot signal and connects to the acoustic transceiver and receives the first electric measurement signal and the second electric measurement signal. The control unit measures the geometric parameters of the pipeline based on the first and second electric measurement signals.
