Rosemount 5300 Series
October 2014
High pressure steam applications
Considerations
Saturated steam under high pressure can influence radar level transmitter measurements.
Rosemount 5301 with Dynamic Vapor Compensation will automatically compensate for this
and maintain the level accuracy.
 Probe type 3V (for 3- to 4-in. chambers) or 4U (for 2-in. chambers) must be used.
 Mount in a 2-, 3-, or 4-in. bypass chamber with flanges appropriately sized for the pressure
and temperature of the application.
 Dynamic Vapor Compensation requires a minimum distance from the flange to the surface
level in order to measure the change in the vapor dielectric constant. If the level rises within
this area, the unit switches over to static compensation, using the last known vapor dielectric
constant.
 If a 5300 Series transmitter is ordered from Rosemount together with a 9901 Chamber, these
space requirements are met by using the option code G1or 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.
 Always ensure that there are no disturbances from inlets etc close to the reference reflector
end when using probe type 4U.
Minimum measuring span:
12 in. (300 mm)
Level: 0%
Level: 100%
Probe Type 3V Probe Type 4U
Short reflector (option code R1):
Minimum 22 in. (560 mm)
Long reflector (option code R2):
Minimum 28 in. (710 mm)
Minimum measuring span:
12 in. (300 mm)
Level: 0%
Level: 100%
Short reflector (option code R1):
Minimum 22 in. (560 mm)
Long reflector (option code R2):
Minimum 28 in. (710 mm)
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.
