Radar Tank Gauge
Roof Reflector
Measurements on floating roofs are not recommended
for highly accurate measurements due to the unsteady
movements of the floating roofs. A special reflector can
be used for applications on floating roofs (not for 7532
RTG with planar antenna!).
Optimum mounting position
• Positioning of the reflector on a floating roof:
• The upper edges of the reflector have to be aligned
horizontally.
• For slanted locations (e.g. dome-shaped floating
roof), the feet must be extended accordingly.
Construction hints
The construction serves as retroreflector such that a
tank roof incline does not influence the measured value.
The cross-sectional area shouldn‘t be smaller than
specified in the figure above to receive and transmit
enough energy
The construction should be open in the bottom part to
allow rainwater to drop out. Thin stainless steel sheets
should be used, to prevent the construction from
becoming too heavy.
Note! The roof reflector is not part of the standard offering
from Varec. Please contact Varec for further information.
