Abstract: A system and method for determining a physical parameter of a pipe-fluid system includes providing a mechanical vibration spectrum of the pipe-fluid system, which is generated by a mechanical excitation impacting an outer surface of the pipe-fluid system, providing characteristic data of a pipe of the pipe-fluid system, providing process-fluid data of the pipe-fluid system, determining a mechanical model vibration spectrum based on a provided theoretical model for the pipe-fluid system and the provided characteristic data of the pipe and the provided process-fluid data, and comparing the mechanical vibration spectrum and the model vibration spectrum for determining the physical parameter of the pipe-fluid system for determining the physical parameter of the pipe-fluid system.
