To avoid strong buildup and dust in the antenna system, the sensor
should not be mounted directly at the dust extraction of the vessel.
In case of extreme dust deposits in the antenna system, VEGAPULS
68 is available with a rinsing air connection. The air is distributed via
channels in the antenna system and keeps it largely free of dust.
