Chamber / pipe installations
Rosemount 9901 Chamber
Rosemount 9901 allows external mounting
of process level instrumentation. It supports
a variety of process connections, and
optional drain and vent connections. The
Rosemount 9901 chamber is designed to the
ASME B31.3 standard, and is Pressure
Equipment Directive (PED) compliant. Use
option code XC to order together with the
5300 Series transmitters.
The probe length to use for a Rosemount
9901 chamber can be calculated by using
Table 13 on page 53.
Use a centering disc if the probe length >3.3
ft (1 m). See “Probe Type in Chamber
Considerations” on page 52 and “Centering
Discs” on page 52 for which probe and disc to
use.
For additional information, see the Rosemount 9901 Chamber for Process Level
Instrumentation Product Data Sheet (Document Number 00813-0100-4601) and the
Combining Guided Wave Radar with Rosemount 9901 Chambers Technical Note (Document
Number 00840-0100-4601).
Existing Chamber
A Rosemount 5300 Series transmitter is the perfect
replacement in an existing displacer chamber.
Proprietary flanges are offered, enabling use of
existing chambers to make installation easy.
Considerations when changing to 5300:
 The 5300 series flange choice and probe length
must be correctly matched to the chamber. Both
standard ANSI and EN (DIN), as well as proprietary
chamber flanges, are available. See “Special
flanges and flushing connection rings” on page 77
to identify the proprietary flanges.
 See “Probe Type in Chamber Considerations” on
page 52 and “Centering Discs” on page 52 for which probe and disc to use. See Table 14 on
page 53 for guidelines on the required probe length.
For additional information, see the Replacing Displacers with Guided Wave Radar Technical
Note (Document Number 00840-2200-4811).
