Installation

2.3 Installation considerations

2.3.1 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” on page 1.

For material compatibility considerations, see technical note 00816-0100-3045 on

www.rosemount.com.

2.3.2 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 Figure 2-5 on page 17, keeping drain/vent

connections on the bottom for gas service and on the top for liquid service.

2.3.3 Environmental

Access requirements and “Cover installation” on page 2-13 can help optimize transmitter

performance. Mount the transmitter to minimize ambient temperature changes, vibration,

mechanical shock, and to avoid external contact with corrosive materials. “Specifications and

Reference Data” on page 9 lists temperature operating limits.

2.4 Installation procedures

2.4.1 Configure security and alarm

Configure security (Write protect)

Changes to the transmitter configuration data can be prevented with the security (write

protect) switch located on the feature board. See 2-1 for the location of the switch. Position the

switch in the “ON” position to prevent accidental or deliberate change of configuration data.
