• The minimum measuring span for the Dynamic Vapor Compensation functionality is
12 in. (300 mm).
• The long reflector, 20 in. (500 mm), has the best accuracy and is recommended for all
chambers where the dimensions of the chamber allow for it.
• If the distance from the flange to the upper inlet is less than 28 in. (710 mm), the short
reflector should be chosen. This distance is a minimum when dynamic compensation is
required within the whole measuring range from the lower to the upper inlet. If this is
not required, the long reflector can be used and dynamic compensation is possible up
to 28 in. (710 mm) from the flange.
• If a Rosemount 5300 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
