Mounting cladded flanges
• Use flange screws according to the number of flange holes.
• Tighten the screws with the required torque (see table).
• Retighten the screws after 24 hours or after the first temperature cycle.
• Depending on process pressure and process temperature check and retighten the screws at
regular intervals.
Usually, the PTFE flange cladding also serves as a seal between the nozzle and the device
flange.

Horn antenna (FMR51)
Alignment
• Align the antenna vertically to the product surface.
The maximum range may be reduced if the horn antenna is not vertically aligned.
• A marking at the flange (somewhere between the flange holes) or the boss enables alignment of
the antenna. This marking must be aligned towards the tank wall as well as possible.
