VEGA VEGAPULS 65 (≥ 2.0.0 - ≤ 3.8) 4 … 20 mA_HART four-wire - Manual (Page 17)

Fig. 8: Recommended socket mounting
I n 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.
A lign the sensor in liquids as vertical as possible to the product surface
to achieve optimum measurement.

T he mounting location of the radar sensor should be a place where no
other equipment or fixtures cross the path of the microwave signals.
V essel 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.
I n case of existing vessel installations, a false echo storage should be
carried out during setup.
I f large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
S
mall, inclined sheet metal baffles above the installations scatter the
radar signals and prevent direct interfering reflections.
