This guide provides basic guidelines for Rosemount 405. It does not provide instructions for configuration,
diagnostics, maintenance, service, troubleshooting, Explosion-pr oof, Flameproof, or intrinsically safe (I.S.)
installations. Refer to the Rosemount 405 Reference Manual (document number 00809-0100-4810) for
more instruction. This manual is also available electronically on www.rosemount.com.
If the Rosemount 405 was ordered assembled to a Rosemount
Rosemount 3051SFC Compact Flowmeter. See the following Quick Start Guide for information on
configuration and hazardous locations certifications: Rosemount 3051S Series Pressure Transmitter
(document number 00825-0100-4801).
If the Rosemount 405 was ordered assembled to a Rosemount 3051S MultiVariable™ Tra nsm itt er, th e ne w

information on configuration and hazardous locations certifications: 3051S MultiVariable Transmitter
(document number 00825-0100-4803).
Process leaks may cause harm or result in death.
To avoid process leaks, use only gaskets designed to seal with the corresponding flange and O-rings to seal
process connections.
To ensure correct operation download the most current version of the Engineering Assistant software at:
Install the Rosemount 405 in the correct location within the piping branch to
prevent inaccurate measurement caused by flow disturbances.

Note
Recommended lengths are represented in pipe diameters. If longer lengths of straight run
are available, position the Rosemount 405 so 80% of the pipe run is upstream and 20% is
downstream.
Flow conditioners may be used to reduce the required straight run length, improving
performance.

2.0 Primary element orientation
The primary element can be installed in any position around the circumference of
the pipe, provided the vents are positioned properly for bleeding or venting.
Optimal results for liquid or steam in a vertical line are obtained when flow is up.

Top mounting for steam
Top mounting in steam is an alternative mounting method for steam installations
that can be used if there are space restrictions or other concerns. This installation
method is intended for applications that run with limited interruptions or
shutdowns. Also, for outdoor applications, top mounting can eliminate the need
for heat tracing, if steam is flowing.

June 2016
Note
For the Rosemount 405A Model in wet steam applications, do not mount the flowmeter at
the direct vertical position. Mounting at an angle will avoid measurement inaccuracy due to
water running along the bottom of the pipe.

Figure 9. Remote mount up to 850 °F (454 °C) – 405C, 405P, and 405A
Note
When top mounting with a remote mount transmitter, use enough impulse piping to
dissipate the process heat to avoid damaging the transmitter.
Quick Start Guide
Suggested top mounting orientations:
For steam up to 400 °F (204 °C) use direct mount orientation and for steam up
to 850 °F (454 °C) use remote mount orientation.
For direct mounting, ambient temperature should be less than 100 °F (38 °C).
For remote mount installations, the impulse piping should slope up slightly
from the instrument connections on the Rosemount 405A Model to the cross
fittings, allowing condensate to drain back into the pipe.
From the cross fittings, the impulse piping should be routed downward to the
transmitter and the drain legs. The transmitter should be located below the
instrument connections of the Rosemount 405A Model.
For technologies C, P, and A, depending on the environmental conditions, it may
be necessary to insulate the mounting hardware.

Quick Start Guide
3.0 Primary element installation
1. Orient the assembly according to the guidelines provided in “Primary element
orientation” on page 5. Ensure the flow arrow stamped on the
405 Primary Element is pointing in the same direction as the process flow.
Note
ANSI 150 - 600# alignment ring is included as standard when ordering for up to 8-in. line
sizes. For the 10-in. and 12-in. line size, the alignment ring must be ordered (Installation
Accessories). 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 or tape does 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
Rosemount 405.
4. Place the alignment ring on the Rosemount 405 body (see Figure 10 ).
5. Insert gaskets.
6. Insert the Rosemount 405 between the flanges so 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 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.
Step 9 through Step 12 are for use with alignment rings that have through holes.
9. Place the alignment ring on the Rosemount 405 body (see “Horizontal gas” on
page 6).
10. Insert the Rosemount 405 between the flanges.
a. Starting on the side opposite the Rosemount 405 head, rotate the
alignment ring such that the radius corresponding to the alignment ring
marking matches that of the application flange rating.
b. Insert one stud through both the upstream and downstream flanges and
allow the ring to rest on the bolt. This will ensure proper alignment.
11. Repeat Step 10 for the installation of the remaining bolts that will contact the
alignment ring.
12. Insert gaskets.
13. Install remaining studs and nuts (hand tight). Ensure 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.

Quick Start Guide
Note
Standa rd 1/16-in. gaskets are recommended for use with the Rosemount 405. Using other
gaskets could potentially cause a bias shift in the measurement.
3.1 Recommended insulation guidelines
For flowmeters with integral temperature assembly:
It is recommended that the meter be insulated when the difference between
process and ambient temperature is greater than 30 °F (16.6 °C).
1. For line sizes
4-in. (100 mm) of insulation of at least a 4.35 R-factor.
2. For line sizes 6-in. (150 mm) to 12-in. (300 mm), it is recommended to have
5-in. (125 mm) of insulation of at least a 4.35 R-factor.
The full thickness stated above may not be necessary for the entire flowmeter,
but is required for the temperature sensor area at a minimum. Insulation is
needed to ensure meeting our specified temperature measurement accuracy.
Insulation should only be placed up to the neck and not cover the transmitter.
