3.6 Installation recommendations for solids
CAUTION!
Do not install the device above objects in the silo (ladder, supports etc.). Objects in the silo can
cause parasite radar signals. If there are parasite radar signals, the device will not measure
correctly.
If it is not possible to install the device on another part of the silo, do an empty spectrum scan.
INFORMATION!
We recommend that you configure the device when the silo is empty.
INFORMATION!
For the best device performance, the antenna should be silo-intrusive. Refer to the illustration
that follows.
Figure 3-7: General installation recommendations
1 The level transmitter can continue to measure to the bottom of the silo if you tilt the device as shown in the illustration
(a 2° slanted flange option is available for all antennas)
2 We recommend that you do an empty spectrum recording if there are too many obstacles in the radar beam. For more
data, refer to How to make a filter to remove radar signal interference on page 62.
3 Conical silo bottoms. For fine adjustment of the device, refer to How to measure correctly in silos with curved or conical
bottoms on page 63.
4 Beam radius (DN80 horn antenna): increments of 90 mm/m or 1.1¨/ft (5°)
Beam radius (DN100 horn antenna, DN150 horn antenna, DN200 horn antenna or DN80 Drop antenna): increments of
70 mm/m or 0.83¨/ft (4°)
Beam radius (DN150 Drop antenna): increments of 35 mm/m or 0.42¨/ft (2°)
