Emerson Rosemount 3051S MultiVariable - Installation Considerations

WARNING
Spare parts
Replacement equipment or spare parts not approved by Emerson
™
for use as spare parts
could reduce the pressure retaining capabilities of the transmitter and may render the
instrument dangerous.
Use only bolts supplied or sold by Emerson as spare parts.
CAUTION
Improper assembly
Improper assembly of manifolds to traditional flange can damage sensor module.
For safe assembly of manifold to traditional flange, bolts must break back plane of flange
web (i.e., bolt hole) but must not contact sensor module housing.
3.3 Installation considerations
3.3.1 General
Measurement performance depends upon proper installation of the transmitter, impulse
piping, and process temperature sensor. Mount the transmitter close to the process and
use minimum piping to achieve best performance. Also, consider the need for easy access,
personnel safety, practical field calibration, and a suitable transmitter environment. Install
the transmitter to minimize vibration, shock, and temperature fluctuation.
Note
Install the enclosed pipe plug (found in the box) in the unused conduit opening if optional
process temperature input is not used. For proper straight and tapered thread
engagement requirements, see the appropriate approvals drawings in Product
Certifications.
For material compatibility considerations, see the Material Selection Technical Note.
3.3.2
Mechanical
For steam service or for applications with process temperatures greater than the limits of
the transmitter, do not blow down impulse piping through the transmitter. Flush lines
with the blocking valves closed and refill lines with water before resuming measurement.
When the transmitter is mounted on its side, position the coplanar flange to ensure proper
venting or draining. Mount the flange as shown in Bolt installation, keeping drain/vent
connections on the bottom for gas service and on the top for liquid service.
3.3.3
Environmental
Access requirements and Cover installation can help optimize transmitter performance.
Mount the transmitter to minimize ambient temperature changes, vibration, mechanical
