Installation
Dimensions: Waveguide
Notes:
You can connect a maximum of two waveguides together.
This option is recommended only for clean liquids on vessels without agitators or
turbulence.
Horizontal stress on this antenna must be avoided, otherwise mechanical support
may be required.
Process temperature and pressure capabilities are dependent upon information on
the process device tag. Reference drawing listed on the tag is available upon
request.
The Process Device Tag shall remain with the process pressure boundary assembly.
In the event the instrument package is replaced, the Process Device Tag shall be
transferred to the replacement unit.
WARNING: The user is responsible for the selection of bolting and
gasket materials which will fall within the limits of the flange and
its intended use and which are suitable for the service conditions.
