Horn antenna (FMR51)
Alignment
• Align the antenna perpendicular to the product surface.
The maximum reach of the antenna can be reduced if it is not installed perpendicular to the
product.
• A marking is provided on the flange (at a point between the flange holes), the threaded
connection or the gland to aid the alignment. This marking must be aligned towards the
tank wall as much as possible.
