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.
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. Review “Location and Orientation” on page 2-2.
4. Confirm the 1595 configuration.
5. 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.
6. Install the orifice plate.
7. Check for leaks.
8. Commission the orifice plate.
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.

LOCATION AND
ORIENTATION
The orifice plate electronics must be installed in the proper orientation relative
to the pipe and the fluid measured.
Horizontal Pipe
Installation
NOTE
The maximum acceptable temperature is –100 to 700 °F (-73 to 370 °C).
Gas in Horizontal Pipes
The electronics should be mounted above the pipe to ensure that condensate
does not collect on the transmitter sensing diaphragms. Orient the unit within
the 120°recommended zone as shown in Figure 2-1.

Liquid or Steam in Horizontal Pipes
The electronics should be mounted below the pipe to ensure that gases do
not collect on the transmitter sensing diaphragms.
