To the owner:
Thank you for purchasing an OMEGA FPD
Series Flowmeter. Please take a few minutes to read through the manual before installing and operating your meter. If you
have any problems with the meter, refer to
the Maintenance and Troubleshooting sections of the manual.
This manual contains connection and operating instructions for the OMEGA FPD
Series meters with pulse outputs. This includes the following models:
FPD1202-HP FPD1203-HP
The OMEGA FPD Series flowmeter has incorporated the oval rotor principal into its
design. This has proven to be a reliable and
highly accurate method of measuring flow.
Exceptional repeatability and high accuracy
over a wide range of fluid viscosities and
flowrates are features of the OMEGA FPD
Series flowmeter design. With low pressure
drop and high pressure rating, means the
OMEGA FPD Series flowmeters are suitable for both gravity and pump (in-line) applications.
INSTALLATION
1. Use thread sealant on all pipe threads.
2. Ensure the meter is installed so that
rotor shafts are always in a horizontal
plane (See Figure 1). Flow is bi-directional.
Figure 1
DO NOT install
meter this way.
3. OMEGA recommends use of flexible
connections.
4. Extreme care must be taken when installing the meter. Pipe strain or overtightening meter connections can
cause meter damage.

IMPORTANT INFORMATION
Please read this information

▲
carefully before use!
Before use, confirm the fluid to be used is
compatible with the meter or consult with
OMEGA for advice.
To prevent damage from dirt or foreign
matter, OMEGA recommends a Y or basket type 200 mesh strainer be installed as
close as possible to the inlet side of the
meter. (If required, contact OMEGA for further information.)
To prevent damage to the meter, slowly fill
the system with fluid. This will prevent damage caused by air purge.
NOTE: Failure to do this could damage the
meter.
For pump applications, turn off the pump
at the end of each day.

MAINTENANCE
Disassembly:
1. Ensure the fluid supply to the meter has
been disconnected, and the line pressure has been released before disassembly.
2. Remove the four screws and remove the
pulser cap.
3. Remove the gasket.
4. Remove eight screws and remove the
meter cap.
5. Remove O-ring and inspect. Replace Oring if damaged.
6. Remove rotors, clean and inspect. Replace rotors if damaged.
7. To remove the PCB, remove the two
screws.
NOTE: Reed Switch PCB’s cannot be re-
moved.
Reassembly:
1. Replace rotors into the meter body. The
rotors should be at 90 degrees to each
other.
2. Lightly rotate the rotors by hand. They
must rotate freely.
3. Install O-ring.
4. Replace the meter cap and tighten the
eight screws uniformly to 35Nm (25 Ft.
Lbs.).
5. Replace the pulser cap and tighten the
four screws.
