For your safety, review the major warn-
ings and cautions below before operat-
ing your equipment.
The apparatus enclosure may con-
tain aluminum and is considered to
constitute a potential risk of ignition
by impact or friction. Care must be
taken into account during installa-
tion and use to prevent impact or
friction.
Part of the enclosure is constructed
from plastic. To prevent the risk of
electrostatic sparking the plastic
surface should only be cleaned with
a damp cloth.
1. Use only fluids that are compatible
with the housing material and wet-
ted components of your turbine.
2. When measuring flammable liq-
uids, observe precautions against
fire or explosion.
3. When handling hazardous liquids,
always follow the liquid manufac-
turer’s safety precautions.
4. When working in hazardous envi-
ronments, always exercise appro-
priate safety precautions.
5. Always dispose of used cleaning
solvents in a safe manner accord-
ing to the solvent manufacturer’s in-
structions.
6. During turbine removal, liquid may
spill. Follow the liquid manufac-
turer’s safety precautions for
cleanup of minor spills.
7. Do not blow compressed air
through the turbine.
8. Do not allow liquids to dry inside the
turbine.
9. Handle the rotor carefully. Even
small scratches or nicks can affect
accuracy.
10. When tightening the turbine, use a
wrench only on the wrench flats.
11. For best results, always verify ac-
curacy before use.
Produ t Des ription
FLOMEC® Industrial Meter Turbines
are identified by the internal diameter of
the inlet and outlet.
Model 05 – 1/2 inch
Model 07 – 3/4 inch
Model 10 – 1 inch
Model 15 – 1-1/2 inch
Model 20 – 2 inch
Each turbine is designed to work with
onboard computer electronics and/or
with one of several accessory output
modules.
Liquid flows through the turbine hous-
ing causing an internal rotor to spin. As
the rotor spins, an electrical signal is
generated in the pickup coil. This signal
is converted into engineering units (gal-
lons, litres, etc.) on the local display.
Accessory modules can be used to ex-
port the signal to other equipment.
Upon receipt, examine your meter for
visible damage. The turbine is a preci-
sion measuring instrument and should
be handled as such. Remove the pro-
tective plugs and caps for a thorough
inspection. If any items are damaged or
missing, contact your distributor.
Make sure the turbine model meets
your specific needs. Refer to the Spec-
ifications Section and confirm the fol-
lowing:
1. The flowrate is within the limits of
your model.
2. The liquid is compatible with the tur-
bine’s wetted components.
3. The system’s pressure does not ex-
ceed the turbine’s maximum pres-
sure rating.

lon (PPG).
INSTALLATION
For your future reference, it might be
useful to record this information in the
manual in case it becomes unreadable
on the turbine.
All FLOMEC® turbines are designed to
measure flow in only one direction. The
direction is indicated by the arrow,
cast-molded in the turbine.
Flow altering devices such as elbows,
valves, and reducers can affect accu-
racy. See Diagram 1. The following rec-
ommended guidelines are given to en-
hance accuracy and maximize perfor-
mance. Distances given here are mini-
mum requirements; double them for
desired straight pipe lengths.
Upstream from the turbine, allow a min-
imum straight pipe length at least 10
times the internal diameter of the tur-
bine. For example, with the 1-inch tur-
bine, there should be 10 inches (25.4
cm) of straight pipe immediately up-
stream. The desired upstream straight
pipe length is 20 inches (50.8 cm).
Downstream from the turbine, allow a
minimum straight pipe length at least 5
times the internal diameter of your tur-
bine. For example, with the 1-inch tur-
bine, there should be 5 inches (12.7
cm) of straight pipe immediately down-
stream. The desired downstream dis-
tance is 10 inches (25.4 cm). See Dia-
gram 2.

A typical backpressure of 5 to 50 PSI
(0.34 to 3.4 bar) will prevent cavitation.
Create backpressure by installing a
control valve on the downstream side
of the meter at the proper distance de-
tailed above.
Foreign material in the liquid being
measured can clog the turbine’s rotor
and adversely affect accuracy. If this
problem is anticipated or experienced,
install screens to filter impurities from
incoming liquids.

To ensure accurate measurement, re-
move all air from the system before
use.
Threaded Conne tions
1. To protect against leakage, seal all
threads with an appropriate sealing
compound. Make sure the sealing
compound does not intrude into the
flow path.
2. Make sure the arrow on the outlet is
pointed in the direction of the flow.
3. Tighten the turbine onto the fittings.
Use a wrench only on wrench flats.
Note: If connecting to new male
threads, burrs and curls can ad-
versely affect accuracy. Correct
the problem prior to turbine in-
stallation.
Verify accuracy after connections are
complete. See Operation section.
ANSI Flange Conne tion
Use a gasket between the meter flange
and mating flange. Determine the ma-
terial of the gasket based on the oper-
ating conditions and type of fluid.
Note: Do not over tighten the flange
bolts. This may cause the gas-
ket to be compressed into the
flow stream and may decrease
the accuracy of the meter. See
ANSI flange specification sec-
tion for flange installation dia-
gram.
Verify accuracy after connections are
complete. See Operation section.
Tri-Clover
®
Flange
Conne tion
1. Make sure the arrow on the outlet is
pointed in the direction of the flow.
2. Insert a gasket between the meter
fitting and the mating fitting. Deter-
mine the gasket material based on
the operating conditions and the
type of fluid used.
3. Fasten with the appropriate clamp.
Tighten clamp to manufacturer’s
specifications.
Verify accuracy after connections are
complete. See Operation section.

OPERATION
Verify A ura y
Before use, check the turbine’s accu-
racy and verify calibration.
1. Make sure there is no air in the sys-
tem.
2. Measure an exact known volume
into an accurate container.
3. Verify the volume against the
readout or recording equipment.
Note: If necessary, use a correction
factor to figure final volume.
For best results, accuracy should be
verified periodically as part of a routine
maintenance schedule.
MAINTENANCE
Removing the Turbine
During turbine removal, liquid may
spill. Follow the liquid manufac-
turer’s safety precautions for
cleanup of minor spills.
1. Drain all liquid from the turbine.
Wear protective clothing as neces-
sary.
2. Disconnect both ends of the tur-
bine. For threaded connections,
loosen both ends of the turbine us-
ing a wrench only on the turbine’s
wrench flats.
3. If the turbine is not immediately in-
stalled again, cap lines as neces-
sary.
Cleaning the Turbine
During use, the turbine should be kept
full of liquid to ensure that drying does
not occur inside the turbine. If drying or
caking should occur, the rotor will stick
or drag, affecting accuracy. To deter-
mine if the rotor is stuck or dragging,
gently blow air through the meter and
listen for the quiet whir of the rotor.
Never blow compressed air through
the meter. It could damage the rotor.
1. Remove the turbine from the sys-
tem following the directions below.
2. Carefully clean residue off all parts.
Remove internal parts as detailed
above. Note orientation carefully for
correct assembly. Internal parts can
be soaked for 10 to 15 minutes in
compatible cleaning solutions.
3. Use a soft brush or small probe to
carefully remove residue from the
rotor.
Follow the liquid manufacturer’s in-
structions for the disposal of con-
taminated cleaning solvents.
3. When the rotor turns freely, assem-
ble and install it again following the in-
structions above.
4. Check accuracy after cleaning. See
Diagram 3 for example of bucket test
method.

Repla ing Internal Parts
1. Remove the turbine from the sys-
tem as detailed above.
Note: Carefully notice the orientation of
all internal parts as they are re-
moved, especially the orientation
of the rotor to the flow direction
arrow. See Figure 2.
2. Using a small tool such as a screw-
driver or awl, gently pry one retain-
ing ring from its groove. Remove
the support. If necessary, use nee-
dle nose pliers. Little or no force
should be required.
3. Carefully remove the rotor.
Handle the rotor carefully. Even
small scratches or nicks can affect
accuracy.
4. Turn the turbine over and remove
the other retaining ring. Remove
the other support.
5. Clean, as detailed below, or discard
as necessary.
6. Replace one support and retaining
ring. Parts should drop easily into
place with little or no force.
7. Install the rotor. Make sure the wide
end of the rotor’s blades faces the
flow direction. See Figure 3.
8. Turn the turbine over and drop the
second support into place. Put the
final retaining ring into position.
9. Reinstall the turbine, purge the sys-
tem of air, and verify accuracy be-
fore use.
