3.3.1 Installation considerations
Measurement accuracy depends upon proper installation of the transmitter and impulse
piping. Mount the transmitter close to the process and use a minimum of piping to
achieve best accuracy. Keep in mind 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.
Important
Install the enclosed pipe plug (found in the box) in unused conduit opening. Engage a
minimum of five threads to comply with explosion-proof requirements. For material
compatibility considerations, see Material Selection
Rosemount.
3.3.2 Environmental considerations
Best practice is to mount the transmitter in an environment that has minimal ambient
temperature change. The transmitter electronics temperature operating limits are –40 to
185 °F (–40 to 85 °C). Mount the transmitter so that it is not susceptible to vibration and
mechanical shock and does not have external contact with corrosive materials.
3.3.3 Mechanical considerations
Steam service
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.

Installation procedures

3.4.1 Mount the transmitter
The following are approximate weights of each transmitter:
• Rosemount 2088 2.44 lb (1,11 kg)
• Rosemount 2090F 2.74 lb (1.24 kg)
• Rosemount 2090P 2.96 lb (1.34 kg)
In many cases its compact size and light weight makes it possible to mount directly to the
respective apparatus without using an additional mounting bracket. When this is not
desirable, mount directly to a wall, panel, or two-inch pipe using the optional mounting
bracket (see
For dimensional drawing information refer to
