Rosemount 5300 Series
Replacing a Displacer in an Existing Displacer Cage
A Rosemount 5300 Series transmitter is the perfect
replacement in an existing displacer cage.
Proprietary flanges are offered, enabling use of
existing cages which makes installation easy.
5300 Benefits
• No moving parts: Less need for maintenance -
costs dramatically reduced, and as a result,
also improved measurement availability.
• Reliable measurement, independent of
density, turbulence, and vibrations.
Considerations when changing to 5300
When changing from a displacer to a Rosemount
5300 Series transmitter, make sure to correctly
match the 5300 series flange choice and probe
length to the cage. Both standard ANSI and EN (DIN)
as well as proprietary cage flanges are available.
See “Dimensional Drawings” on page 31 to identify
the proprietary flanges.
With rigid probes, the risk of touching the tank wall is
minor, so they are preferred in small diameter pipes
and bypass cages.
The single lead probe is the best choice. It is
excellent for interface measurements with a
submerged probe. It is good for viscous and dirty
liquids.
The twin lead probe has the same usage as the
single probe, except it is not suitable for
heavy-deposit liquids.
Both probe styles are easy to clean.
The coaxial probe measures best for low-dielectric
and clean fluids. It is not recommended for
submerged probe applications.
The following table gives guidelines on the required
probe length.
Centering Discs
In order to prevent the probe from contacting the
bridle wall when replacing displacers or installing in
pipes, centering discs are available for stainless steel
rigid single, flexible single and flexible twin lead
probes. The disc is attached to the end of the probe
and thus keeps the probe centered in the bridle. The
discs are made of stainless steel or PTFE.
The centering disc in PTFE is not available for HTHP
probes.
Vented Flanges and Flushing Connection Rings
The 5300 Series is available with vented flanges.
These flanges are designed with threaded
connection (model code RA) and are ordered as
accessories. As an alternative to a vented flange, it is
possible to use a flushing connection ring on top of
the standard nozzle (see “Special Flanges and
Flushing Connection Rings” on page 31).
