VEGA VEGAPULS 65 (≥ 2.0.0 - ≤ 3.8) Foundation Fieldbus - Manual (Page 17)

Fig. 8: Recommended socket mounting
In case of very big socket diameters, the active antenna part can be
slightly recessed in the socket. The following rule applies to the
standard version of VEGAPULS 65: Socket diameter corresponds to
max. socket height.
Align the sensor in liquids as vertical as possible to the product surface
to achieve optimum measurement.

The mounting location of the radar sensor should be a place where no
other equipment or fixtures cross the path of the microwave signals.
Vessel installations such as, for example, ladders, limit switches,
heating spirals, struts, etc. can cause false echoes that get super-
imposed on the useful echo. Make sure when planning your measuring
site that the radar sensor has a "clear view" to the measured product.
In case of existing vessel installations, a false echo storage should be
carried out during setup.
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
Small, inclined sheet metal baffles above the installations scatter the
radar signals and prevent direct interfering reflections.
