The antenna must project out of the nozzle. If necessary, use an antenna extension. But if the
tank roof is flat and the tank fitting is symmetrical, it is not necessary for the antenna to project
out of the nozzle. Thus, the device can have a larger measuring range.
Do an Empty Spectrum recording (refer to Operation Operation Operation Operation) to remove parasitic signals with a filter.

1 If the roof is not flat, the antenna must project out of the nozzle
2 Short tank nozzle
3 Long tank nozzle (device with an antenna extension)
4 If the roof is flat and the tank fitting is symmetrical, it is not necessary for the antenna to project out of the nozzle.
Thus, the device can have a larger measuring range.

Recommended height of tank process connection, a = 44...200 mm / 1.7...7.87¨
1 Device with a PTFE Wave Horn antenna and a flange connection. There are antenna extension options available
(100 mm / 4¨, 200 mm / 8¨ and 300 mm / 12¨) for long nozzles.
2 Device with a PP Wave Horn antenna and a thread connection
CAUTION!
If there are parasitic signals, the device will not measure correctly. Parasitic signals are caused
by:
• Objects in the tank.
• Sharp corners that are perpendicular to the path of the radar beam.
• Sudden changes in tank diameter in the path of the radar beam.
