52 VEGAPULS 42 and 44 – 4 … 20 mA
Pipe antenna: The surge pipe open to the bottom
must have a ventilation or equalisation hole on top
Correct
Wrong
VEGAPULS 44 on the surge pipe: The sensor type
plate must be aligned with the rows of holes.

Installation mistakes in the standpipe
Pipe antenna without ventilation hole
Pipe antenna systems must be provided with
a ventilation hole on the upper end of the
surge pipe. A missing hole will cause false
measurements.
Wrong polarisation direction
When measuring in a surge pipe, especially if
there are holes or slots for mixing in the tube,
it is important that the radar sensor is aligned
with the rows of holes.
The two rows of holes (displaced by 180°) of
the measuring tube must be in one plane with
the polarisation direction of the radar signals.
The polarisation direction is always in the
same plane as the type label.
