3.4 Installation recommendations for solids
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.
We recommend that you configure the device when the silo is empty.
For the best device performance, the antenna should be silo-intrusive. Refer to the illustration
that follows.
Figure 3-4: 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
If there are too many objects in the radar footprint, do an empty spectrum scan. Refer to the handbook for the proce-
dure.
3
Conical silo bottoms. Refer to the handbook for fine adjustment of the device.
