A mechanical or acoustic excitation apparatus 26 imparts mechanical vibrations to a pipeline 12 in at least two longitudinally spaced areas of its outer surface. At least one sensor 30 is positioned in proximity to the pipeline, which collects vibration data supplied to it along the pipeline. A processing and analysis apparatus 40 derives from the vibration data information concerning the gas and liquid content of the multiphase fluid, in particular the length and rate of travel of liquid plugs and air pockets, and a control device 42 regulates intake valves of downstream petroleum equipment to adjust the intake flow rate of the phases as a function of the storage and/or treatment capacity of the equipment.
