Technical information / Instruction manual
Improper installation may result in loss of process pressure.
Materials of construction are choosen based on their chemical compatibility (or inertness) for
general purposes. For exposure to specific environments, check with chemical compatibility
charts before installing.
The torque at the fastening spot must not exceed the specified ratings. See page G7 for details.
Keep away from incoming material and from silo walls.
The installation has to be carried out, that the sensor elements cannot hit the wall of the silo. The
flow of the medium and fixtures in the container must be considered.
For devices to be used in Hazardous Locations the respective valid installation regulations must
be observed.
The housing can be rotated against the threaded connection after mounting.
When the unit is mounted from the side, ensure, that the cable glands face downwards and are
closed to avoid water penetration into the housing.
Seal the process connection thread with Teflon tape or a flat gasket against process pressure.
Use teflon tape to avoid seizing of aluminium process connection thread with the socket
A Full detector vertical and oblique from the top
B Full detector horizontal
C Demand or empty detector horizontal
Protective angle recommended, depending on load
D Empty detector oblique from the bottom
Protective angle recommended, depending on load
Horizontal mounting (except full detector) : Boot shaped vane
recommended (min. mech. load, because the vane aligns to the
movement of the material).
