Notes:
• Installation shall only be performed by qualified personnel and in accordance with
local governing regulations.
• This product is susceptible to electrostatic shock. Follow proper grounding
procedures.
• Do not use a Ground Fault Interrupt (G.F.I.) with the SITRANS LR 300. The ground path
is used for filtering purposes in conjunction with the universal power supply.

Installation
Beam Spreading
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 this polarization effect.
False Reflections
Flat obstructions and struts 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.
Minimize false reflections first by rotating the instrument for best signal (lowest false
echo amplitude). Then use the TVT shaper parameters (P831, 832, 837 and 838) to prevent
false echo detection.
(rod antenna or 150mm [6”]
horn antenna)
(200mm [8”] horn antenna)
(100mm [4”] horn antenna)
Keep the emission cone (12o,
20oor 28o, depending on
configuration), free of
obstructions.
Due to the polarization effect of
the microwave signal related to
the wall of the vessel, we
recommend locating the
SITRANS LR 300 a minimum of
30cm (1’) away from the sidewall
for every 3m (10’) of vessel
