In the case of longer nozzles, reduced measuring performance must be expected.
Please note the following:
• The end of the nozzle must be smooth and free from burrs.
• The edge of the nozzle should be rounded.
• Mapping must be performed.
• Please contact the manufacturer's support department for applications with nozzles
that are higher than indicated in the table.
10.3.4 Antenna, PTFE cladded, flush mount 80 mm (3 in)
The cladding on the antenna also acts as a process seal. An additional seal is not
required for installation.
Mounting cladded flanges
Note the following for cladded flanges:
• Use the same number of flange screws as the number of flange bores provided.
• Tighten the screws with the necessary torque (see Table).
• Retighten after 24 hours or after the first temperature cycle.
• Depending on the process pressure and temperature, check and retighten the screws,
where necessary, at regular intervals.
The PTFE flange cladding normally acts simultaneously as a seal between the nozzle and
the device flange.
