GENERAL INFORMATION
This manual will assist you in install-
ing and maintaining your FLOMEC G
Series Turbine. For best results, take
the time to fully acquaint yourself with
all information about all components of
your G Series Turbine. If you need as-
sistance, contact the distributor from
whom you purchased your turbine.
Product Description
FLOMEC G Series Turbine owme-
ters are volumetric ow measurement
devices. The moving uid is used to
turn a rotor, which is suspended in
the ow stream. The rotating speed
of the rotor is proportional to the uid
velocity or owrate. As the blades from
a spinning rotor pass by a magnetic
sensor, an AC voltage pulse is gener-
ated and transmitted to the readout
instrument. Each pulse is equal to a
given volume of liquid, therefore “x”
number of pulses are equal to a gal-
lon, litre, pound, barrel, etc.
Turbine Sizing
FLOMEC G Series Turbines are
identied by the internal diameter of
the inlet and outlet.
Model 050 ½ in. (0.6-6.0 gpm)
Model 051 ½ in. (0.8-6.0 gpm)
Model 075 ¾ in. (1.6-16 gpm)
Model 075E ¾ in. (2.3-23 gpm)
Model 100 1 in. (6.7-67 gpm)
Model 150 1½ in. (17.7-177 gpm)
Model 200 2 in. (33-330 gpm)
Model 300 3 in. (60-600 gpm)
Turbine owmeters should be sized
in accordance to the actual owrate
and not the process pipe size. For
example: a process having a owrate
of 10-20 GPM in a 1-½" process line
requires either a Model 075E or Model
100 turbine owmeter.
Another important factor to take into
consideration when sizing a turbine
owmeter is instantaneous owrate.

3
921977-01C
This is extremely important when
sizing a turbine owmeter where
the volume is measured per hour or
per day. For example, an application
where the total output is 500 barrels
per day, occurring in a 5 hour period;
the recommended turbine owmeter
should be sized according to the
instantaneous owrate:
(500 – 5) x 24 or 2,400 barrels per day
Thus, requiring an 1-½ inch turbine
owmeter.
INSTALLATION
Turbine owmeters are affected by
both upstream and downstream
process configurations. Turbine
owmeters should always be installed
with a minimum of 10 pipe diameters
upstream and 5 pipe diameters
downstream. The only exception is
the placement of the pumps, valves,
etc., on the upstream end. When this
occurs, 20 diameters of straight pipe
should be used. The direction of ow is
indicated by the arrow on the turbine.
All turbine owmeters are designed
to measure ow in only one direction.
Check the items below once the
turbine owmeter is installed in the
process line. This will ensure a suc-
cessful start-up.
1. Before installing the magnetic sen-
sor, make sure that it is functioning
properly.This can be accomplished
by checking the ohm resistance.
RefertoCheckingMagnetic Pickup
in the Troubleshooting section.
2. If a magnetic pickup enclosure is
used on a sanitary turbine, discard
the seal cap that is included with the
unit. If no enclosure is used, install
the magnetic pickup and slip the
seal cap over the magnetic pickup
and threads on the adapter.
NOTE: This is not applicable for units
that use a low prole adapter.
3. Check the interconnection cable
between the turbine owmeter and
readout device. Refer to Checking
the Cable Assembly section.
4. Make sure that the new or correct
K-factor is entered into the readout
device.
Initial Start-Up
Turbine owmeters can be installed
in the horizontal or vertical position.
When installing a turbine owmeter
in the vertical position, it is important
that the direction of ow be up through
the turbine owmeter.
A spool should be installed in place
of the turbine owmeter during initial
start-up of a new process line. The
process line should be purged, thus
eliminating any solids contained in
the line. Once this is completed, the
spool can be removed and the turbine
owmeter installed.
Whenever possible, use 20 straight
pipe diameters upstream and down-
stream of the turbine owmeter. The
length of straight pipe upstream and
downstream of the turbine owmeter
can be reduced with the use of ow
straighteners or straightening vanes.
A minimum of 10 straight pipe diam-
eters upstream and 5 downstream
are required.
NOTE: Control valves should always
be installed downstream of the
turbine owmeter.
The turbine owmeter should be
installed in a location where the pro-
cess line will remain full of liquid at all
times. Otherwise, when the process
line becomes empty and a valve is
opened, the high velocity uid hitting
the turbine owmeter rotor can cause
severe damage.
When there is entrained air in the
process line, an air eliminator should
be used. This entrained air causes
air pockets and these air pockets

4921977-01C
will cause the rotor to spin at a faster
rate than liquid, thus resulting in in-
correct readings, which results in an
overstatement of actual owrate and
volume. This condition can damage
the owmeter.
In process lines where particulates
are present, a lter/strainer should
be used. Refer to the table below for
the recommended mesh size.

MAINTENANCE
Disassembling the Turbine
1. Disconnect the turbine owmeter
cable from the magnetic pickup.
Refer to Figure 1.
2. Remove the magnetic pickup.
3. Ensure that the process line is
depressurized and empty prior to
removal of the turbine owmeter.
Remove the turbine owmeter from
the process line.
4. Using a small screwdriver or similar
tool, insert it into the radius notch
of the retaining ring, pull away from
the groove and up, removing the
retaining ring from one end of the
turbine owmeter. This will allow
the support to slide out of the
turbine owmeter body. Remove
the rotor before proceeding to the
other support.
NOTE: To remove the other support,
simply repeat this operation.
If liquid being measured by
sleeved bearing turbine owme-
ters contains large solids, install a
lter or strainer. Without the use
of a lter or strainer, damage can
occur to the internal components.
WARNING

921977-01C
5. Once the turbine owmeter is taken
apart, inspect the turbine owmeter
body for signs of wear or defects.
The body bore should be smooth
and show no evidence of wear.
NOTE: Do not install a new replace-
ment kit into a turbine owmeter
body that shows signicant signs
of wear.
6. Examine the rotor for broken and/
or bent blades.
7. Examine the supports for signs of
deterioration, such as wear marks
and/or burrs along the outer edge
of the support vanes.
8. When the rotor or the supports
show any sign of deterioration,
a new replacement kit should
be installed. Do not install a new
replacement kit into a defective
turbine owmeter body.
Replacement Kits
A replacement kit is comprised of all
the internal component parts within
the turbine owmeter. A replacement
kit consists of the following:
Parts Description Quantity
Rotor Assembly 1
Support Assembly*2
Retaining Ring 2
*The support assemblies come complete with bush-
ings and thrust balls, which are factory installed.
Proper selection of bearing material is critical when
ordering a new replacement kit.
FLOMEC®supports are identical in
design, thus eliminating assembly er-
ror. Each support incorporates a thrust
bearing, which allows for bidirectional
ow and prevents damage to the rotor
and/or supports in the event the tur-
bine owmeter is installed backwards
with respect to the direction of ow.
Notice that the direction of ow is
displayed on the body of the turbine
owmeter. This is important when
installing the rotor and also denotes
the direction in which the turbine
owmeter was calibrated.
NOTE: FLOMEC rotorsare taperedon
one end (except ½" and ¾"). The
tapered end should be installed
on the inlet side. See Figure 1.
The ½" and ¾" rotors are marked
with a point on the hub and should
be installed with the marked side
of the rotor hub on the inlet side.
1. Install a support on the inlet side
(where the ow starts), placing a
vane between the notches in the
turbine owmeter body. Install a
retaining ring – this will keep the
support in place.
2. Place the rotor with the shaft in
the support that has not been in-
stalled. Hold the turbine owmeter
body with the open end down and
slide the rotor and support into the
turbine owmeter body. Make sure
the vane is placed between the
notches.
3. Once the support is in place, install
the retaining ring.
4. Blow into the turbine owmeter to
ensure the rotor spins freely.
Installation of the replacement kit is
complete and the turbine owmeter
can be reinstalled into the process line.
5. Install the magnetic pickup. HAND
TIGHTEN ONLY.
NOTE: Be sure to use the proper
magnetic pickup, cable and con-
nector for the application.
6. Enter the new K-factor supplied
with the replacement kit into the
electronic readout device. (Refer
to the calibration report.)
NOTE: All internal replacement kits
are factory calibrated and are sup-
plied with a ve point calibration
certicate.

can be either Local or Remote. Remote
electronics include FLOMEC Remote
Displays or output to customer supplied
equipment. Follow the next three steps
when choosing a magnetic pickup .
1. Select your size: ½ in. or ¾ to 3 in.
2. Choose Local or Remote/Output.
Local uses a wire lead pickup. Re-
mote/Output requires a connector.
3. Choose either Sine Wave or
Square Wave as your signal
type. Sine Wave does not require
external power for sensor and can
be used with battery powered dis-
plays. Square Wave means sensor
power is required.

TROUBLESHOOTING
Locating the Problem
To determine the location of the
problem, whether it is occuring at the
turbine owmeter or at the electronic
readout device, disconnect the cable
assembly from the magnetic pickup
and connect the cable from the por-
table rate indicator onto the magnetic
pickup. Refer to Figure 6.
The portable rate indicator will dis-
play the instantaneous rate of ow
through the turbine owmeter. If the
rate displayed is equal to the rate of
the process, then both the magnetic
pickup and the turbine owmeter are
operational. The problem will be lo-
cated either in the cable assembly or
the electronic readout device.
When there is no rate displayed on
the portable rate indicator, the prob-
lem may be caused by a defective
magnetic pickup or turbine owmeter.
Checking the Magnetic
Pickup
To determine the status of a hermeti-
cally sealed, two-wire lead, or stan-
dard magnetic pickup, simply remove
it from the turbine owmeter, and us-
ing an ohm meter, measure the ohm
resistance by placing the leads of the
ohm meter on each pin of the mag-
netic pickup. Refer to Figure 7. If the
ohm meter reads 1400 ohms ±20%,
Figure 6
Model R150
Hand-held
Portable Rate
Indicator
then the magnetic pickup is good and
should NOT be replaced. If the ohm
meter reads less than 1000 ohms,
install a new magnetic pickup. DO
NOT throw the old magnetic pickup
away. Failure of the magnetic pickup
may have been caused by moisture
trapped inside. In some cases when
the magnetic pickup is allowed to dry,
it has become completely functional
and can be reused. When the ohm
meter reads in excess of 1700 ohms,
the magnetic pickup is defective and
should be discarded.
NOTE: It is recommended that the
ohm resistance be measured
before installing a used magnetic
pickup.
Checking the Turbine
Flowmeter
Once it has been determined that
the magnetic pickup is functional
and there is no output displayed on
the portable rate indicator, it can be
concluded that the problem lies within
the turbine owmeter. Remove the
turbine owmeter from the process
line. DO NOT remove the internals
at this time.
Visually inspect the internals of the
turbine owmeter. Check for particu-
lates and/or foreign objects which may
have lodged between the rotor and
the body. In the event an object is
detected, simply remove the retaining
ring on the outlet side of the turbine
owmeter and remove the support
and rotor assembly. Once the turbine
Figure 7

11
921977-01C
owmeter parts are free from any
foreign matter, reassemble.
NOTE: Always ensure that a sup-
port vane is installed between the
indention marks on the body.
Upon completion, verify the rotor spins
freely, reinstall the turbine owmeter
into the process line.
If there are no signs of particulates or
any other foreign matter obstructing
the rotor, try blowing into the turbine
owmeter. If the rotor does not spin
freely, insert a thin screwdriver or
similar tool, gently so as not to dam-
age any of the rotor blades, and turn
the rotor.
There may be another cause for the
rotor to drag or stop, incorrect bearing
material used for the application. For
example, noncompatibility of the bear-
ing material with the process liquid,
bearing material may not withstand
the temperature of the application, etc.
When there is uncertainty with respect
to the selection of bearing material
for a given application, contact GPI.
Before installing a new replacement
kit, inspect the turbine owmeter body
for wear and damage. By placing your
nger inside the turbine owmeter
body, feel for any signs of wear such
as grooves, ridges, irregular spots. If
such signs are evident, it is a strong
possibility that the turbine owmeter
body is damaged and the installa-
tion of a new replacement kit is NOT
recommended.
When a new replacement kit is
installed inside a damaged turbine
owmeter body, the internals will be
ruined after a short period of operation
and will have to be discarded. In the
event it is uncertain whether or not the
turbine owmeter body is functional,
it should be sent to GPI so the I.D.
dimension of the turbine owmeter
body bore can be checked. If it is
found to be within tolerance, a new
set of internals will be installed. This
will eliminate the possibility of using
and/or discarding a turbine owmeter
which shows signs of wear.
NOTE: A good turbine owmeter body
should have a smooth inner bore
free of wear signs.
If it is determined the turbine owmeter
body is in good condition, install a
new replacement kit and reinstall the
turbine owmeter into the process line.
Checking the Cable
Assembly
This can be accomplished with the aid
of a frequency oscillator. Simply plug
the cable assembly with the mating
connector end that is located at the
turbine owmeter into the frequency
oscillator. The frequency oscillator
will simulate the output of a turbine
owmeter. If an output is displayed
on the electronic readout device, then
the cable assembly is good.
In the event an output is not displayed,
disconnect the frequency oscillator
from the cable assembly and connect
the cable supplied with the frequency
oscillator directly to the electronic
readout device, the same as you
would a turbine owmeter cable as-
sembly. Refer to Figure 8.
Figure 8

12 921977-01C
When the frequency oscillator is con-
nected and an output is displayed on
the electronic readout device, this indi-
cates that the turbine owmeter cable
assembly is defective and should be
replaced. If no output is displayed, the
turbine owmeter cable assembly is
good and the problem lies within the
electronic readout device.
Checking the Electronics
Using the frequency oscillator and
the cable that is supplied, connect
it to the electronic readout device,
the same as you would a turbine
owmeter cable assembly. Once the
frequency oscillator is connected, if no
output is displayed on the electronic
readout device, check to ensure that
the power is on, the fuses are good,
and the correct K-factor is dialed/
programmed into the electronic
readout device. After verication of
these items, if there is still no output
displayed and/or registered, then the
manufacturer of the electronic readout
device should be consulted.
