To the owner:
Thank you for purchasing an OMEGA FPD
Series Flowmeter. Please take a few min-
utes to read through the manual before in-
stalling and operating your meter. If you
have any problems with the meter, refer to
the Maintenance and Troubleshooting sec-
tions of the manual.
This manual contains connection and op-
erating instructions for the OMEGA FPD
Series meters with pulse outputs. This in-
cludes the following models:
FPD1202-HP
The OMEGA FPD Series flowmeter has in-
corporated 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 suit-
able for both gravity and pump (in-line) ap-
plications.
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 bas-
ket type 200 mesh strainer be installed as
close as possible to the inlet side of the
meter. (If required, contact OMEGA for fur-
ther information.)
To prevent damage to the meter, slowly fill
the system with fluid. This will prevent dam-
age 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.
FPD1203-HP
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-direc-
tional.
3. OMEGA recommends use of flexible
connections.
4. Extreme care must be taken when in-
stalling the meter. Pipe strain or over-
tightening meter connections can
cause meter damage.
