vessel radius
On dished vessel tops, please do not mount
the instrument in the centre or close to the
vessel wall, but approx.½ vessel radius from
the centre or from the vessel wall.
Dished tank tops can act as paraboloidal
reflectors. If the radar sensor is placed in the
focal point of the parabolic tank top, the radar
sensor receives amplified false echoes. The
radar sensor should be mounted outside the
focal point. Parabolically amplified echoes are
thereby avoided.

Mounting and installation
3.2 Measurement of liquids
Sensor on DIN socket piece
Radar sensors are usually mounted on short
DIN socket pieces. The lower side of the
instrument flange is the reference plane for
the measuring range. The antenna must
always protrude out of the flange pipe.
Mounting on short DIN socket piece
Reference plane
If the DIN socket piece is longer, please
make sure that the horn antenna protrudes at
least 10 mm out of the socket.
When mounting on dished or rounded vessel
tops, the antenna must also protrude at least
10 mm (long socket side).
