In a hydrocarbon well, a speed measurement is performed at substantially the same level as a determination of the proportions of the phases of the fluid flowing along the well in at least one local region. To this end, local sensors are placed on the hinged arms of a centering device, and a speed-measuring spinner is placed between the arms.
