Emerson Rosemount 1195 User Manual

2-7
Functional Limitations The ProPlate/Mass ProPlate best produces accurate and repeatable
flow measurement under the following conditions:
• The maximum differential pressure is not exceeded.
• The ProPlate is not used for two-phase flow or for steam service
below saturation temperature.
Install the ProPlate in the correct location within the piping branch to
prevent measurement inaccuracies caused by flow disturbances.
Straight Run Requirements Use Figure 2-2 to determine the proper ProPlate straight run
requirements.
NOTES
If longer lengths of straight run are available, position the ProPlate
where 80% of the run is upstream of the ProPlate and 20% is
downstream.
Straightening vanes may be used to reduce the required straight run
length and will improve performance.
Environmental
Considerations
Location of the ProPlate/Mass ProPlate in pulsating flow will cause a
noisy signal. Vibration can also distort the output signal and
compromise the structural limits of the flowmeter. Mount the ProPlate
in a secure run of pipe as far as possible from pulsation sources such as
check valves, reciprocating compressors or pumps, and control valves.
Mount the transmitter to minimize ambient temperature changes.
Section 15: Specifications and Reference Data lists the temperature
operating limits. Mount the transmitter to avoid vibration and
mechanical shock; also avoid external contact with corrosive materials.
See Section 10: Specifications and Reference Data for environmental
considerations.
Access Requirements
When choosing an installation location and position, take into account
the need for access to the ProPlate.
Process Flange Orientation
The process flanges must be oriented so that process connections can be
made. In addition, consider the possible need for a testing or calibration
input. Drain/ vent valves must be oriented so that the process fluid is
directed away from technicians when the valves are used.
Housing Rotation
The electronics housing may be rotated to improve field access to the
two compartments. To rotate the housing less than 90 degrees, release
the housing rotation set screw and turn the housing not more than 90
degrees from the orientations shown in Figure 2-11. To rotate the
housing greater than 90 degrees, consult factory. Rotating the housing
greater than 90 degrees without performing the disassembly procedure
may damage the Mass ProPlate sensor module.
