Replacing a displacer in an existing displacer chamber
A Rosemount 5300 Series Transmitter is the perfect replacement for an existing displacer
chamber. To simplify installation, proprietary flanges are offered to allow for using the same
chambers.

Rosemount 5300 benefits
No moving parts: Less maintenance - dramatically reduced costs, and as a result,
improved measurement availability
Reliable measurement, that is independent of density, turbulence, and vibrations
Considerations when changing to Rosemount 5300
When changing from a displacer to a Rosemount 5300 Series Transmitter, make sure to
correctly match the Rosemount 5300 Series flange choice and probe length to the
chamber. Both standard ANSI and EN (DIN), as well as proprietary chamber flanges are
available.
