SYSTEM FOR DETERMINING THE RELIEF OF A SURFACE FOR FILLING A PETROCHEMICAL REACTOR WITH GRANULES

摘要

The invention relates to a system (22) for determining the relief d of a surface for filling a petrochemical reactor with granules, the direction of filling of the reactor defining a vertical direction, the reactor having a central vertical axis (X), the system comprising a transmitter (24) designed to be positioned above the filling surface so as to transmit a signal to various points of this surface. The system includes means (26) for moving the transmitter (24) through an angle of greater than 60° relative to the central axis (X) of the reactor.
