Key considerations

Correct location is critical to a successful application.

Avoid reflective interference from vessel walls and obstructions by following the guidelines below.

Nozzle design

Bottom edge of horn must project from nozzle.

Nozzle must allow adequate clearance to allow positioning if LR 460 has to be at an angle so that emission cone perpendicular to material surface.

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. (See Easy Aimer Installation on page 15.)

To compensate for vessels with obstructions, see also Polarization Reference Point on page 14.
