• Avoid reflective interference from vessel walls and obstructions by following the
Nozzle design
• Bottom edge of horn must project from nozzle.
• Nozzle must have adequate clearance to allow LR460 to be positioned at an angle (see

Nozzle location
• Locate antenna at least 1 meter away from
• Keep emission cone free of interference
• Make allowance for beam spread to avoid
Device orientation
Align the antenna so that the radar cone is
perpendicular to the surface of the monitored
material, if possible.

Holding the electronics enclosure firmly,
loosen the Easy Aimer ball locking bolts and
gently reposition the enclosure (see
design above).
Direct SITRANS LR460 so the horn antenna
is pointed at an angle perpendicular to the material surface, if possible. (As a guide, aim
the beam at a point approximately 2/3 of the way across the tank diameter.)
When the desired position is reached, re-tighten the 5 bolts to 15-23 N m (11 to 17 Lbf-ft).
