For FMP52: Use spring washers in order to compensate a possible creep deformation of the
PTFE cladding between the tank and the device flange; see figure below.
Alternative: Retighten the flange bolts periodically, depending on process temperature and
pressure. Recommended torque: 60 to 100 Nm (44.3 to 73.7 lbf ft).

1 Spring wahsers ensure sufficient preload between the tank and the flange of the FMP52.
Hight and diameter of the nozzle
•
Permissible nozzle diameter: £ 150 mm (6 in).
For larger diameters the near range measuring capability may be reduced.
For nozzles ³ DN300: (® ä 39).
•
Permissible nozzle height
1)
: £ 150 mm (6 in).
For a larger height the near range measuring capability may be reduced.
Larger nozzle heights may be possible in special cases (see sections "Center rod for FMP51 and
FMP52" and "Rod extension/centering HMP40 for FMP54").
With thermally insulated vessels the nozzle should also be insulated in order to prevent
condensate formation.
Center rod for FMP51 and FMP52
For rope probes it may be necessary to use a version with center rod in order to prevent the probe
rod from coming into contact with the nozzle wall. Probes with center rod are available for
FMP51 and FMP52.
