8.7 Process pressure
The maximum permissible process pressure PS is stated on the rating plate and depends
on the fluid temperature.
8.8 Fluid temperature
The maximum permissible fluid temperature of the device depends on the version and the
lining material of the flow tube and is stated on the rating plate. The German Industrial Safety
Act stipulates that very cold or hot components of working equipment must be provided with
guards which prevent physical contact of workers with the respective parts. For this reason
and also to save energy, in practical applications at temperatures of > 60°C, all pipes and
installed measuring instruments are normally thermally insulated.
Refer to Section 8.6 for information on the relation between the fluid temperature and the
ambient temperature limits.
The temperature ranges for use of the device are listed below for the lining materials
