Mounting preparations The instrument is also available in versions with an antenna whose diameter is larger than the process fitting (thread, flange). In such cases the antenna must be disconnected from the process fitting before mounting.

By turning the instrument in the connection flange or mounting boss, the polarisation can be used to reduce the effects of false echoes. The position of the polarisation is marked on the process fitting of the instrument.

In practice, a cleanly constructed mounting socket, if necessary with rounded edges, introduces fewer disturbing influences than an antenna extension. Orientation To measure as much of the vessel volume as possible, the sensor should be aligned so that the measuring beam reaches the lowest level in the vessel.

  • Page 25 4 Mounting The silo walls of multiple chamber silos are often made of profile Mounting in multiple chamber silo walls, such as e.g. profile sheeting, to ensure the required stability. If the radar sensor is mounted very close to a heavily structured vessel wall, considerable false reflections can be generated. Hence the sen- sor should be mounted at a large distance from the separating wall. The optimal mounting position is on the outer wall of the silo with the sensor directed towards the emptying aperture in the silo center.
  • Page 26 4 Mounting To avoid strong buildup and dust in the antenna system, the sensor Dust deposits should not be mounted directly at the dust extraction of the vessel. In case of extreme dust deposits in the antenna system, VEGAPULS SR 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.
