Thewallsofmultiple-chambersilosareoftenmadeofprolematerial,
e.g.prolesheeting,toensuretherequiredstability.Iftheradarsen-
sor is mounted very close to a heavily structured vessel wall, substan-
tialinterferingreectionscanbegenerated.Thusthesensorshould
be mounted at the largest possible distance from the separating wall.
The best mounting location is on the outer wall of the silo, with the
sensor pointing towards the discharge opening in the silo centre. This
can be accomplished, for example, with the mounting strap.
