Mounting and installation
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.
