Mounting: Location/Beam Angle
Due to the polarization effect of
the microwave signal related to
the wall of the vessel, we
recommend locating the IQ160
a minimum of 30 cm (1’) away
from the side wall for every 3 m
(10’) of vessel height.

Polarization Effect
Mounting the unit too close to a wall may cause echoes to disappear at
specific levels due to wave cancellation. A strong false reflection from an
internal tank obstruction can be reduced or eliminated by rotating the unit to
reduce the polarization effect.
False Reflections
Flat obstructions, and struts that are perpendicular to the emission cone,
cause large false reflections. They reflect the radar signal with high amplitude.
Round profile interfering surfaces diffuse reflections of the radar signals and
cause false reflections with low amplitude.
Beam
Angle
Keep the emission cone
free of obstructions.
