SAFETY MESSAGES Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Please refer to
the following safety messages before performing any operation in this section.
Failure to follow these installation guidelines could result in death or serious injury:
• Make sure only qualified personnel perform the installation.
• Remove pressure and drain the pipe assembly prior to installing or removing the
orifice plate.
• If the process fluid is caustic or otherwise hazardous, follow the instruction closely
to prevent mishap.
Checklist The following is a summary of the steps required to complete a 1595
installation.
If this is a new installation, begin with step 1.
If the mounting is already in place, verify that the orifice flange size and rating
match the recommended specification and begin with step 5.
1. Determine where the 1595 is to be place within the piping system.
2. Establish the proper orientation as determined by the intended
service for the orifice plate.
3. Orient the 1595 Conditioning Orifice Plate so the pressure taps are
centered between any two (of four) orifice bore holes. In addition, the
pressure taps should be located at 90° to the plane of the last elbow.
4. Review “Location and Orientation” on page 2-2.
5. Confirm the 1595 configuration.
6. Measure the pipe’s internal diameter (I.D.), preferably at 1 x I.D. from
the orifice flange (upstream or downstream).
NOTE
Providing the pipe’s I.D. at the time of purchasing the 1595 is necessary to
maintain published orifice plate accuracy.
7. Install the orifice plate.
8. Check for leaks.
9. Commission the orifice plate.

1. When an alignment tool is provided, install the alignment tool on the
flange studs shown in Figure 2-7.
2. For Horizontal installation, use the horizontal lift hole (stamped HLH
on paddle) to lift the conditioning orifice plate from a horizontal
position and guide into location between the flanges.
3. For Vertical installation, first use the horizontal lift hole (HLH) to lift the
conditioning orifice plate from a horizontal position to vertical, then
use the vertical lift hole (stamped VLH on paddle) to lift the
conditioning orifice plate vertically and guide into location between
the flanges.

NOTE
To ensure the best possible flow measurement accuracy, Emerson provides
an Official DP Calculation Sheet with every 1595 Conditioning Orifice Plate.
The Official DP Calculation sheet uses the calibration factor which is unique to
that device and is also stamped on the orifice plate. The Official DP
Calculation Sheet displays the expected full scale flow value and the
calculated full scale DP value and is corrected for the unique calibration factor
which is also displayed on the sheet. This full scale DP value should be used
to range a DP transmitter for the referenced application. Or, the calibration
factor should be used as a correction factor when configuring a flow computer
for the Rosemount Conditioning Orifice Plate.
Step 1: Determine the Proper Orientation
See “Location and Orientation” on page 2-2.
Step 2: Weld the Flange Union.
Follow these steps to weld the orifice flanges to the pipe.
1. Depressurize the line using site-specific requirements
2. Prepare the pipe ends.
a. For flanged models, ensure the pipe mounting flange is the same
size or rating.
b. For threaded models, ensure the pipe union or coupling is the
same size pipe thread as the meter section
3. Ensure that the pipe mounting flange is the correct size and rating.
4. Ensure that the flange taps are aligned and level.
5. Weld the orifice flange to the pipe. To avoid serious burns, allow the
orifice flanges to cool before continuing.

Follow these steps to weld the orifice flanges to the pipe.
1. Depressurize the line using site-specific requirements
2. Remove the section of pipe that will be replaced by the meter section
using site-specific requirements
3. Ensure that the pipe mounting flange is the correct size and rating
a. For flanged models, ensure the pipe mounting flange is the same
size or rating.
b. For threaded models, ensure the pipe union or coupling is the
same size pipe thread as the meter section
4. Orient the assembly appropriately for the type of service (liquid, gas,
or steam).
5. Ensure that the I.D. of the meter section and the I.D. of the pipe are
concentric.
6. Complete assembly to the appropriate connections. To avoid serious
burns, allow the orifice flanges to cool before continuing.
