Considerations

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 housing conduit opening with a
minimum of five threads of engagement to comply with explosion-proof requirements.
For material compatibility considerations, see document number 00816-0100-3045 on

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). Refer to
element operating limits. 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. Refer to

Installation procedures

3.4.1

Mount the transmitter

The Rosemount 2088 Transmitter weighs approximately 2.44lb. (1,11 kg). In many cases its
compact size and light weight makes it possible to mount directly to the impulse line 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
