General Information ...................................2
This manual will assist you in installing and
maintaining your GPI 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
assistance, contact the distributor from whom
you purchased your turbine.
Product Description
GPI G Series Turbine owmeters are volu-
metric flow 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 generated 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 gallon,
litre, pound, barrel, etc.

Turbine Sizing
GPI G Series Turbines are identied by the
internal diameter of the inlet and outlet.
Model 050 1/2 inch (0.6-6.0 GPM)
Model 051 1/2 inch (0.8-6.0 GPM)
Model 075 3/4 inch (1.6-16 GPM)
Model 075E 3/4 inch (2.3-23 GPM)
Model 100 1 inch (6.7-67 GPM)
Model 150 1-1/2 inch (17.7-177 GPM)
Model 200 2 inch (33-330 GPM)
Model 300 3 inch (60-600 GPM)
Turbine owmeters should be sized in ac-
cordance to the actual owrate and not the
process pipe size. For example: a process
having a owrate of 10-20 GPM in a 1-1/2"
process line requires either a Model 075E or
Model 100 turbine owmeter.
Another important factor to take into con-
sideration when sizing a turbine owmeter
is instantaneous owrate. 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 1-1/2 inch turbine ow-
meter.
1. Install magnetic pickup (See Figure 1).
2. Make sure that the new or correct Kfactor is entered into the readout device.
NOTE: The K-factor is printed on the turbine
body. The calibration report included
with the product provides several points
along the ow curve.
INSTALLATION
Turbine flowmeters are affected by both
upstream and downstream process congu-
rations. 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 direc-
tion 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 that follow once the turbine
owmeter is installed in the process line. This
will ensure a successful start-up.
Figure 1
Initial Start-Up
Turbine owmeters can be installed in the
horizontal or vertical position. When installing a turbine owmeter in the vertical posi-
tion, 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.
NOTE: Control valves should always be
installed downstream of the turbine
owmeter.

The turbine owmeter should be installed in
a location where the process 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 trapped air in the process line,
an air eliminator should be used. This trapped
air causes air pockets and these air pockets
will cause the rotor to spin at a faster rate than
liquid, thus resulting in incorrect readings,
which results in an overstatement of actual
flowrate and volume. This condition can
damage the owmeter.
WARNING
If liquid being measured contains large
solids, install a lter or strainer. Without
the use of a lter or strainer, damage can
occur to the internal components.
In process lines where particulates are pres-
ent, a lter/strainer should be used. Refer
to the table below for the recommended
mesh size.

MAINTENANCE
Cleaning Procedures
G Series Sanitary Turbines are designed to
be compatible with commercially accepted
methods of both CIP (Cleaned-In-Place)
mechanical cleaning as well as intermittent
SIP (Steam-In-Place) cleaning methods.
If CIP or SIP cleaning methods are not available, manual COP (Cleaning-Out-of-Place)
methods can be used.
Care must be taken during system start-up,
chemical cleaning, air purge or steam cleaning processes to ensure that the turbine rotor
does not over speed as damage can result to
the rotor and/or bearing. Maximum allowable
over range for G Series Turbines is 125%
of maximum rated owrate for intermittent
periods.
A minimum uid velocity of 5 foot per sec-
ond (1.5 meter per second) must be maintained during the CIP process to ensure
adequate cleaning.
Reference: 3-A Accepted Practices for
Permanently Installed Product and Solution Pipelines and Cleaning Systems Used
in Milk and Milk Product Processing
Plants, Number 605-XX as amended for
procedures and recommended owrates.
The following owrates are recommended by
the 3-A Recommended Practices 605-XX to
achieve 5 FPS or 1.5 MPS in the respective
Sanitary Tube size:

Temperature limit for SIP cleaning is primarily limited by the temperature rating on the
magnetic pickup. If the pickup temperature
rating will be exceeded during SIP cleaning,
remove it during the cleaning process or
a higher temperature rated pickup should
be specied. Internal components of the G
Series Sanitary Turbine must be limited to
less than 285°F (140°C). The temperature
and pressure rating of gaskets and clamps
used in the installation must also be taken
into consideration when determining cleaning parameters.
Minimum requirements for effective ster-
ilization with SIP cleaning are to maintain
250°F (121°C) at the coldest point in the
system for a minimum of 30 minutes. This
requires a minimum of 15.3 psig (106 kPa)
saturated steam pressure. Normal recommended maximums for SIP cleaning on G
Series meters is 285°F (140°C) and 39 psig
(269 kPa) saturated steam pressure.
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 depressur-
ized 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.
5. Once the turbine flowmeter is taken
apart, inspect the turbine flowmeter
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 replacement kit
into a turbine owmeter body that shows
signicant signs of wear.
6. Examine the rotor for broken and/or bent
blades. Remove any foreign matter.
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
bushings and thrust balls, which are factory
installed. Proper selection of bearing material is
critical when ordering a new replacement kit.
GPI supports are identical in design, thus
eliminating assembly error. Each support
incorporates a thrust bearing, which allows
for bidirectional ow and prevents damage
to the rotor and/or supports in the event the
turbine 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: GPI rotors are tapered on one end
(except 1/2" and 3/4"). The tapered end
should be installed on the inlet side.
See Figure 1. The 1/2" and 3/4" 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 flowmeter
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 installed. Hold
the turbine flowmeter 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.

Magnetic Pickups
GPI offers two types of magnetic pickups:
Standard and Wire Lead. See Figure 4.
Figure 4
When choosing a magnetic pickup, the turbine meter and electronics are generally already known. Electronics can be either Local
or Remote. Remote electronics include GPI
Remote Displays or output to customer supplied equipment. Follow the next three steps
when choosing a magnetic pickup.
1. Select your size: 1/2 in. or 3/4 to 3 in.
STANDARD
2. Choose Local or Remote/Output. Local
uses a wire lead pickup. Remote/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
