Nozzle Location; Device Orientation; Installation In Vessel With Obstructions - Siemens SITRANS LR460 HART Operating Instructions Manual

Nozzle location

• Locate antenna at least 1 meter away
from side wall.
• Keep emission cone free of
interference from ladders, pipes,
I-beams or filling streams.
• Make allowance for beam spread to
avoid interference with the emission
cone.

Device orientation

• Align the antenna so that the radar
cone is perpendicular to the surface of
the monitored material, if possible.
Easy Aimer Installation

obstructions
Polarization Reference Point
Obstructions such as ladders, pipes, or the fill path, can cause false reflections. To avoid
this, use the Polarization Reference Point to orient the device.
• A small center punch mark provides a polarization reference point.
• To get the best signal, loosen the Easy Aimer ball locking bolts and rotate the device
until the Polarization Reference Point either faces towards the obstruction, or faces
away from the obstruction (at 180 degrees). Tighten ball locking bolts when unit is in
desired position.
