This section describes the orientation, location and alignment limits for installing the
Rosemount 1495 Orifice Plate, 1496 Flange Union. Read it thoroughly before starting the
installation.
2.1 Safety messages
February 2014
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.
2.2 Installation checklist
The following list is a summary of the steps required to complete a Rosemount 1495 Orifice
Plate installation. If this is an entirely new installation, begin with step 1. If the Flange Union is
already in place, verify that the orifice flange size and rating match the recommended specifications, and begin with step 5.
1. Determine where the Rosemount 1495 Orifice Plate, 1496 Flange Union is to be placed
within the piping system.
2. Establish the proper orientation as determined by the intended service for the orifice plate.
3. Review Appendix B: Recommended Installation Requirements .
4. Confirm the Rosemount 1495 and/or 1496 configurations.
5. Measure the pipe’s internal diameter (ID), preferably at 1 x ID from the orifice flange
(upstream or downstream), or at the tap location for flange taps.
Installation, Location, and Orientation

Section 2: Installation, Location, and Orientation
February 2014
NOTE
Providing the pipe internal diameter at the time of purchase is necessary to maintain published
orifice plate accuracy.
6. Install the hardware. Refer to Section 3: Installation instructions for 1495 Orifice Plate
installation and Section 4: Hardware installation for Rosemount 1496 Flange Union for 1496
Orifice flange union installation.
7. Check for leaks.
8. Commission the orifice plate flowmeter.
2.3 Receiving and inspection
Rosemount 1495 Orifice Plates, 1496 Flange Unions are available in different models and with
different options, so it is important to inspect and know which model you have before
beginning installation.
Reference Manual
00809-0100-4792, Rev CB
Upon receipt of the shipment, check the packing list against the material received and the
purchase order. Report any damage to the carrier.
2.4 Installation configuration
The Orifice Flowmeter Assembly must be installed in the proper orientation relative to the pipe
and the fluid measured.
Gas applications
Mount hardware upward to allow moisture to drain out and not fill the impulse piping:
Slope impulse piping at least one inch per foot (8 centimeters per meter) downward
from the transmitter toward the process connection.

Installation, Location, and Orientation
Reference Manual
00809-0100-4792, Rev CB
Liquid applications
Mount hardware downward to allow the escape of trapped vapor in the impulse piping:
Slope impulse piping at least one inch per foot (8 centimeters per meter) upward from
Vent all gas from the liquid piping legs.
Prevent sediment deposits in the impulse piping.
Keep the liquid head balanced on both legs of the impulse piping.
Section 2: Installation, Location, and Orientation
February 2014
the transmitter toward the process connection.
Steam applications
Mount hardware to allow for a water leg in the impulse piping:
In steam or other elevated temperature services, do not allow the temperatures at the
transmitter process flanges to exceed 300 °F (149 °C).
Do not blow down impulse piping through the transmitter. Flush the lines with the
blocking valves closed and refill the lines with water before resuming measurement
Keep the liquid head balanced on both legs of the impulse piping.
Flow
Installation, Location, and Orientation

Section 2: Installation, Location, and Orientation
February 2014
Other installation considerations:
Orient the high side of transmitter to measure upstream of the DP element.
Orient the low side of transmitter to measure downstream of the DP element.
Temperature taps and thermowells should be located downstream of the DP element.
Flow Conditioners and Straighteners are always located upstream of the DP element.
Refer to Appendix B: Recommended Installation Requirements .
The handle of the orifice plate has the word “Inlet” stamped on the side that faces
upstream.
To correct for installation effects, the transmitter should be zeroed after mounting.
2.5 Straight run requirements
To obtain published accuracy, sufficient straight run is required to produce a fully developed
flow profile. Shorter straight run lengths are possible, but accuracy will be affected. Consult the
Factory for further information. Refer to Appendix B: Recommended Installation Requirements
for recommended straight pipe lengths.
