Rosemount 3051N

Mounting

The Rosemount 3051N Pressure Transmitter weighs approximately 6.0 lb

 

(2,7 kg) without additional options. For complete weight information, including

 

options, see “Physical Specifications” in Section 5. Optional mounting

 

brackets available with the Rosemount 3051N allow mounting to a panel or

 

wall. The B4 Bracket Option for use with the Coplanar flange is 316 SST and

 

provided with 316 SST bolts.

 

Bracket option B2 is a polyurethane painted carbon steel bracket designed for

 

use in panel mounting the traditional flange (H2). The B2 bracket is provided

 

with carbon steel bolts.

 

Bracket option BS is a 316LSST bracket provided with carbon steel bolts that

 

is designed for use in panel mounting the traditional flange (option code H2).

 

It is the same bracket used on other Rosemount Nuclear Instruments, Inc.

 

nuclear qualified transmitters, including the Rosemount 1153 Series D and

 

Rosemount 1154.

 

Bracket option PM is a SST pipe mount bracket assembly designed for use in

 

pipe mounting the traditional Flange (option code H2). It is the same bracket

 

used on other Rosemount Nuclear Instruments, Inc. nuclear qualified

 

transmitters, including the Rosemount 1154 Series H.

 

When installing the transmitter to the mounting bracket, torque the mounting

 

bolts to 21 ft.-lbs.

 

Dimensions and typical mounting configurations are contained in this section.

 

 

 

NOTE

 

The transmitter is calibrated in an upright position at the factory. If you mount

 

the transmitter in any other position, the zero point will shift by an amount

 

equivalent to the liquid head caused by the varied mounting position. To reset

 

the zero point, refer to “Sensor Trim” in Section 2.

 

 

 

Mounting Requirements

 

Refer to Figure 3-6for examples of the following mounting configurations:

Liquid Flow Measurement

•Place taps to the side of the line to prevent sediment deposits on the transmitter’s process isolators.

•Mount the transmitter beside or below the taps so gases can 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 liquid will drain into the process line.

Steam Flow Measurement

•Place taps to the side of the line.

•Mount the transmitter below the taps to ensure that the impulse piping will stay filled with condensate.

•Fill impulse lines with water to prevent the steam from contacting the transmitter directly and to ensure accurate measurement start-up.
