Please take a few minutes to read through
the manual before installing and operating
your meter. Always retain this manual for
future reference. 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. This includes the following
models:
FPD1001 FPD1202-IP
FPD1201 FPD1003
FPD1201-IP FPD1203
FPD1002 FPD1103
FPD1202 FPD1203-IP
FPD1102
Part breakdowns for each model are located at the back of this manual. For models
with displays and/or 4-20 mA output, an
additional instruction manual is provided.
The 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 oval rotor design. With low pressure
drop and high pressure rating, oval rotor
flowmeters are suitable for both gravity and
pump (in-line) applications.
OPERATION
Please read this information

carefully before use!
Before use, confirm the fluid to be used is
compatible with the meter. Refer to Industry
fluid compatibility charts or consult your
local representative for advice.
To prevent damage from dirt or foreign
matter it is recommended that a Y or basket type 200 mesh strainer be installed as
close as possible to the inlet side of the
meter. Contact your local representative
for advice.
NOTE: To prevent damage to the meter,
slowly fill the system with fluid (this will
prevent damage caused by air purge).
Failure to do this could damage the
meter.
To reduce pressure build up, turn off the
pump at the end of each day.
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. Flow is bi-directional.
3. OMEGA recommends use of flexible
connections.
4. Extreme care must be taken when
installing the meter. Pipe strain or
overtightening the meter connections
can cause meter damage.

MAINTENANCE
Disassembly:
1. Ensure the fluid supply to the meter
has been disconnected, and the line
pressure has been released before
disassembly.
2. Remove four (4) screws and remove
the meter body cover.
3. Remove O-ring and inspect. Replace
O-ring if damaged.
4. Remove rotors, clean and inspect.
Replace rotors if damaged.
Reassembly:
1. Place rotors into the meter body. The
rotors should be at 90 degrees to each
other.
NOTE: The rotor with magnets must be
placed in the body on the same side
as the groove on the body. (Refer to
diagram.)
2. Lightly rotate the rotors by hand. (They
must rotate freely.)
3. Install O-ring.
4. Replace the meter cap.
NOTE: The groove on the cover must line
up with the groove on the meter body.
(Refer to diagram.)
5. Replace the four screws.
