Abstract
The invention relates to a system for determining relief on a granule filling surface in a petrochemical reactor, the filling direction in which the reactor is filled defining a vertical direction, the reactor having a central vertical axis, the system including a transmitter configured to be positioned above the filling surface in such a manner as to transmit a signal to various points of said surface. The system includes shift means for shifting the transmitter about the central axis of the reactor through an angle that is great than 60°.
