The sensor must be directed with the hole to the rows
of holes or openings.
Hole
DN 50

Mounting and installation
Lockable measuring pipe on a pipe antenna system
Ball valve
Rows of holes in one axis with the hole
Polarisation direction
For reasons of radar signal polarisation the
holes and slots must be positioned in two
rows displaced by 180
°
. The mounting of the
radar sensors must then be such that the
hole of the sensor which is in the intermediate
flange, is in one axis with the row of holes of
the standpipe.
Standpipe with ball valve
When using a ball valve in a surge pipe, it is
possible to carry out maintenance and ser-
vice work without opening the vessel (e.g.
with liquid gas or toxic products).
The ball valve diameter must correspond to
the pipe size and provide a flush surface
when in open position.
Note that the surge pipe ventilation is avail-
able.
