Caution!
If there is a risk of electrostatic discharge from the product, then both processconnection and rope
must be earthed before the probe is lowered into the silo.
Levelflex can be screwed into a threaded socket or flange. Proceed as follows:
Insert probe
• Uncoil rope and lower it slowly and carefully
into the silo.
• Do not kink the rope
• Avoid any backlash, since this mightdamage
the probe or the silo fittings.

• Note!
– For flange mounting: if a seal is used, be
sure to use unpainted metal bolts toensure
good electrical contact betweenprobe flange
and process flange.
Screw down
• Screw the Levelflex into the process
connection or to flange.
• When using an aramid fibre seal and a process
