Reference Manual

October 2010

Rosemount 3051S Series

2-10

Suite includes: Statistical Process Monitoring (SPM), Power Advisory, Status

Log, Variable Log, Advanced Process Alerts, Service Alerts, and Time Stamp

capability.

The Advanced HART Diagnostics Electronics can be ordered using option

code DA2 in the transmitter model number or as a spare part (p/n

03151-9071-0001) to retrofit existing 3051S transmitters in the field. See

Section 7 Advanced HART Diagnostics of this manual for more information.

NOTE

Option code DA2 or spare part (p/n 03151-9071-000X) are limited to a T4

temperature rating.

Mounting Requirements

Impulse piping configurations depend on specific measurement conditions.

Refer to Figure 2-3 for examples of the following mounting configurations:

Liquid Flow Measurement

• Place taps to the side of the line to prevent sediment deposits on the

process isolators.

• Mount the transmitter beside or below the taps so gases vent into the

process line.

• Mount drain/vent valve upward to allow gases to vent.

Gas Flow Measurement

• Place taps in the top or side of the line.

• Mount the transmitter beside or above the taps so to drain liquid into

the process line.

Steam Flow Measurement

• Place taps to the side of the line.

• Mount the transmitter below the taps to ensure that impulse piping will

remain filled with condensate.

• In steam service above 250 °F (121 °C), fill impulse lines with water to

prevent steam from contacting the transmitter directly and to ensure

accurate measurement start-up.

NOTE

For steam or other elevated temperature services, it is important that

temperatures at the process connection do not exceed the transmitter’s

process temperature limits. See “Process Temperature Limits” on page A-11

for details.
