CONSIDERATIONS
General Measurement performance depends upon proper installation of the
transmitter and impulse piping. 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.
IMPORTANT
Install the enclosed pipe plug (found in the box) in the unused conduit
opening. For straight threads, a minimum of 6 threads must be engaged. For
tapered threads, install the plug wrench-tight.
For material compatibility considerations, see document number
00816-0100-3045 on www.rosemount.com.
Mechanical 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.
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and terminals.
Process leaks could result in death or serious injury.
• Install and tighten all four flange bolts before applying pressure.
• Do not attempt to loosen or remove flange bolts while the transmitter is
in service.
Replacement equipment or spare parts not approved by Rosemount Inc. for use
as spare parts could reduce the pressure retaining capabilities of the transmitter
and may render the instrument dangerous.
• Use only bolts supplied or sold by Rosemount Inc. as spare parts.
Improper assembly of manifolds to traditional flange can damage SuperModule
™
Platform.
• For safe assembly of manifold to traditional flange, bolts must break back
plane of flange web (i.e., bolt hole) but must not contact module housing.
SuperModule and electronics housing must have equivalent approval labeling in
order to maintain hazardous location approvals.
• When upgrading, verify SuperModule and electronics housing certifications are
equivalent. Differences in temperature class ratings may exist, in which case
the complete assembly takes the lowest of the individual component
temperature classes (for example, a T4/T5 rated electronics housing
assembled to a T4 rated SuperModule is a T4 rated transmitter.)
