CONSIDERATIONS
Functional The Rosemount 405 produces the most accurate and repeatable
measurement when it is used in single-phase flow or steam flow above the
saturation temperature. Location of the 405 in pulsating flow will cause a
noisy signal. Vibration can also distort the output signal and compromise the
structural limits of the flowmeter.
Mount the 405 in a secure run of pipe as far as possible from pulsation
sources such as check valves, reciprocating compressors or pumps, and
control valves.
Install the 405 in the correct location within the piping branch to prevent
measurement inaccuracies caused by flow disturbances.
Maximum temperature for direct mount applications is 450 °F
(232 °C). Maximum temperature for remote mount applications is 850 °F
(454 °C).
Vibration Limits
Qualified per IEC61298-3 (1998) for field with high vibration level or pipeline
with high vibration level (10-60Hz 0.21mm displacement peak amplitude / 60 500Hz 3g).
The weight and length of the transmitter assembly shall not exceed 5.8 lbs
and 7.75-in.

Liquid or Steam in Vertical or Horizontal Pipes
Mount the transmitter below the 405 with the instrument lines sloping up.
NOTE
The 405 should not be used in vertical liquid or steam applications if the fluid
is flowing down.
Process Connections

The 405 is available with either ¼-in. – 18 NPT connections (standard) or
½-in. – 14 NPT connections (option code E). The ½-in. connections can be
rotated to attain connection centers of 2-in. (51 mm), 2
¼-in. (57 mm). The threads are Class 2; use a lubricant or sealant when
making the process connections.
Ensure all four flange studs are installed and tightened prior to applying
pressure to prevent process leakage. When properly installed, the flange
studs will protrude through the top of the module housing.
NOTE
Do not attempt to loosen or remove the flange studs while the 405 is in
service.
Perform the following to install flange adapters to the head of the 405.
1. Place o-ring in the groove on bottom of the flange adapter.
2. Position flange adapters over NPT connections on the adapter plate.
3. Insert studs through 405 head, adapter plate, and flange adapters.
4. Thread nuts onto studs. Tighten nuts to 300 in-lbs. (34 N-m).

O-RING
When compressed, PTFE o-rings tend to cold flow, which aids in their sealing
capabilities. When removing adapter plates or adapters, visually inspect the
o-rings. Replace them if there are any signs of damage, such as nicks or cuts.
If they are undamaged, you may reuse them. If you replace the o-rings,
retorque the nuts after installation to compensate for cold flow.
High Temperature Units (Option Code T)

Inconel
o-rings should be replaced any time the unit is disassembled.
INSTALLATION Install the 405 according to the procedure below.
1. Orient the assembly according to the guidelines provided in "Location
and Orientation" beginning on page 2-4. Ensure that the flow arrow is
pointing in the same direction as the process flow.
NOTE
An ANSI alignment ring is provided standard with the 405. If a DIN or JIS
alignment ring is required, it must be ordered as an option. Contact an
Emerson Process Management sales representative for additional
information.
NOTE
For ease of installation, the gasket may be secured to the flange face with
small pieces of tape. Be sure the gasket and/or tape do not protrude into the
pipe.
2. If using an alignment ring with through holes, proceed to step 9.
3. Insert two studs through the flange holes located opposite the head of
the 405.

4. Place the alignment ring on the 405 body (see Figure 2-10).
5. Insert gaskets.
6. Insert the 405 between the flanges so that the indentations on the
alignment ring contact the installed studs. The studs must contact the
alignment ring in the indentation marked with the appropriate flange
rating to ensure proper alignment.
7. Install remaining studs and nuts (hand tight). Ensure that three of the
studs are in contact with the alignment ring.
8. Lubricate studs and tighten nuts in a cross pattern to the appropriate
torque per local standards.
Steps 9-12 are for use with alignment rings that have through holes.
9. Place the alignment ring on the 405 body (see Figure 2-10).
10. Insert the 405 between the flanges. Insert one stud through the
flange hole located opposite the 405 head; passing through the
alignment ring through hole and the opposite flange hole. The stud
must contact the alignment ring through the through hole marked with
the appropriate flange rating to ensure proper alignment.
11. Repeat step 10 for a second (2) stud opposite the 405 head.
12. Insert gaskets.
13. Install remaining studs and nuts (hand tight). Ensure that three of the
studs are in contact with the alignment ring.
14. Lubricate studs and tighten nuts in a cross pattern to the appropriate
torque per local standards.
