If a Rosemount 5300 Series GWR transmitter is ordered from Rosemount together
with a Rosemount 9901 Chamber, these space requirements are met by using the
option code G1 or G2 for the chamber. G1 is used with the short reference reflector
and G2 is used with the long reference reflector.
If an existing chamber is used, which does not meet these space requirements, a
spool piece can be added. For the 4U probe, the spool piece needs to be at least 2
in. (50 mm) longer or shorter than the reference reflector, to ensure that there are
no disturbances from welds close to the reference reflector end. For a spool piece
with the 3V probe, this is not a requirement.
For the 4U probe, the spool piece needs
to be at least 2 in. (50 mm) longer or
shorter than the reference reflector.
For a spool piece with the 3V probe, this
is not a requirement.
