1.2 A TYPICAL INSERTION TURBINE FLOW METER
ONICON’s Insertion Turbine Flow Meters
measure the velocity of flowing liquids
by counting the frequency at which the
blades of a rotating turbine pass a fixed
electrode. Circuitry within the flow meter
electronics enclosure then converts the
rotational rate to digital and/or analog
signals which are transmitted via a
connecting cable to any of ONICON’s
display devices, BTU meters and/or a
data acquisition system.

SECTION 2.0: UNPACKING
Insertion Flow Meters are generally shipped in one package unless optional hardware or
equipment is ordered. This package may contain up to two complete meters along with the
optional installation kits. If any display equipment was ordered with the meters, the other
equipment will be packed separately. Please open all packages with caution to prevent
damage to their contents. In the event that they are damaged when you receive them, notify
the shipping company immediately and the ONICON Customer Service Department. All
products are shipped insured unless customer specifically requests otherwise.
2.1 CHECKING THAT YOU HAVE RECEIVED EVERYTHING
• The Documentation
Enclosed with each Insertion Flow Meter is a comprehensive documentation package
which includes the following items:
! OWNER’S MANUAL
! FLOW METER CALIBRATION DATA SHEETS
Please notify the ONICON customer service department if any of these documents are
missing.
• The Flow Meter
The flow meter is a rugged instrument and should arrive without any damage;
however, prior to installation, inspect it for physical damage such as broken turbine
blades or a damaged stem.
! Test the turbine(s) to see that they rotate freely when you blow on them
parallel to their shafts.
! Make sure that the threads on the hot tap adapter have not been damaged.
! Inspect the long stem for bends or other damage. The stem forms the seal
against liquid leakage as it slides through an ‘O’ ring outside the hot tap
adapter. Deep scratches may cause leakage.
! The serial and model numbers on the wire connection/calibration data tag
should match the numbers on the tag mounted directly on the flow meter. Be
sure that the unit was calibrated to the correct pipe size and flow range.

SECTION 3.0: INSTALLATION, REMOVAL & ADJUSTMENT
***CAUTION***
Insertion Flow Meters may often be installed in pipes which are under high
pressure. Accidents with these systems can cause serious injury or death. Only
!
3.1 SITE SELECTION
Install the flow meter where it will be accessible for personnel to perform necessary periodic
maintenance. The clearance required for installation is typically 30-36” from the pipe wall to
the nearest obstruction above the valve assembly. This clearance dimension will increase
with large diameter pipes. The environment should be free of corrosive liquids/fumes,
temperature extremes and heavy vibration. The following diagrams should be used as a guide
to the proper location for installing the meter.
persons experienced with high pressure systems and related knowledge in the
heating, cooling and fluid metering fields should attempt to install adjust or remove
the flow meter. Refer to the installation drawings before performing any work on
these meters.
ONICON will be happy to assist with technical recommendations and to provide
guidance by telephone and/or mail. On-site field engineering, installation and service
is also available at additional cost.
If yours is a single turbine meter and there is no suitable location, contact ONICON’s Sales
Office to discuss upgrading to a dual turbine meter. This meter is more tolerant of the
conditions that cause swirl, turbulence and flow profile distortions. Please make this decision
before installing the single turbine meter so that we may be able to give you credit if you elect
to upgrade to a dual turbine meter. Returns may be subject to a restocking charge.

3.2 MECHANICAL INSTALLATION
Turbine meters may require periodic maintenance and you should be able to remove the
meter when necessary without shutting down your system. To take advantage of the ONICON
Flow Meter’s built-in Hot Tap feature, it must be installed through an isolation valve. The
location must allow sufficient overhead clearance for meter removal (for cleaning and
preventative maintenance). A full 1” opening is required to clear the turbine assembly. Make
sure that your valves and fittings are full port and at least 1” in actual internal diameter. Also,
note that an oversized access hole can cause undesirable turbulence.
Try to limit the overall height from the pipe’s outside diameter to the top of the valve to 5½ 6”. ONICON calculates the stem length of the flow meter based on pipe size and this nominal
height. If your installation requires a taller fitting assembly and the dimension was not
specified on the order form, please contact the factory before installation. This way ONICON
can offer you credit for your meter if you decide to exchange it for one with a longer stem.
Returns may be subject to a restocking fee.
ONICON’s Standard Installation Hardware
kit is for use in a drained, non-pressurized
system. The access hole is drilled (1”
minimum) prior to installation of the 1”
NPT branch outlet, close nipple and full
port ball valve. Once the isolation valve is
installed, the piping system can be flushed
and pressurized. The flow meter may now
be inserted or removed by hand without
having to drain the system. Please read all
instructions before proceeding with meter
insertion.
ONICON’s Hot Tap Installation Hardware
kit offers an alternative installation when it
is not practical to drain or relieve the
pressure in the system. In this case, a 1¼”
branch outlet, close nipple and 1¼” full
port ball valve are installed first. Then, a
hot tap drilling apparatus can be used to
drill a 1” diameter hole through the valve,
without shutting down or draining the pipe.

When you are ready to refill the system, make sure that all lines are filled with
water before inserting the turbine into the stream. If the lines are not filled, air may
!
After fitting the necessary plumbing hardware, flush the
entire system so that it is free of flux, solder and slag. Prepare
to install the flow meter by loosening the clamping nut and
withdrawing the turbine assembly fully into the hot tap
adapter. Next, thread the adapter on to the ball valve using a
paste type thread sealant. Do not use Teflon tape because
torn strands of the tape may wind around the turbine,
slowing down or even stopping the turbine.
Check the installation for leaks by slightly opening the ball
valve under the hot tap adapter. An ‘O’ ring in the adapter
seals the meter stem against leakage. If there are any leaks
around the clamping nut or stem, DO NOT ATTEMPT TO
STOP THE LEAKAGE BY OVERTIGHTENING THE
CLAMPING NUT. Damage to this nut or the clamping ring
under the nut may prevent the assembly from properly holding the meter in the pipe. The
clamping nut is not part of the sealing mechanism. Any leaks in this area indicate that the ‘O’
ring is not sealing properly and you must contact the factory for assistance.
interrupt the flowing stream and damage the turbine assembly. A greater danger is
that if this is a hot water system, some water may flash into steam and exceed the
high temperature limit for the turbine and its mechanical assembly. This flash over
could exceed the pressure ratings of the meter and the assembly could fail allowing
steam and hot water to escape causing serious injury.
3.3 INSERTION OF THE METER
SYSTEM MAY BE UNDER HIGH PRESSURE. When adjusting the meter position or
!
Begin by calculating the effort that will be required to hold the meter. Establish adequate
footing for this task, taking extra caution when working from a ladder or platform. Use the
following formula:
E=0.11xP Where: E = effort in pounds
P = system pressure in pounds per square inch
removing it, be sure to hold the electronics enclosure firmly by hand before
SLOWLY loosening the positioning clamping nut. Failure to do this will allow the
pressure to suddenly and rapidly force the meter from the pipe causing serious
injury. The meter could also be damaged or break apart causing a break in the water
seal with the resultant loss of large amounts of water. The hand effort required to
hold the meter will be 0.11 times the pipe pressure.
Example: In a 300 PSI system, 33 pounds of effort is required to insert the meter into the pipe.

• Installing the meter with a factory supplied
depth gage:
1. Open valve completely, loosen the
position clamping nut, and insert the
meter until the bottom of the electronics
case touches the eye of the depth gage.
(Pierce insulation with gage until the tip
touches the pipe.)
2. Position the electronics enclosure parallel
to the pipe in the direction relative to the
flow. This will position the turbine with
its axis in line with the flow and in the
correct direction.
3. Tighten the position clamping nut.
Do not release the flow meter until you have tightened the position clamping nut
enough to hold the flow meter in the desired position. This will require less torque
than you might think, so be careful not to overtighten it and risk damaging the
adapter, nut or stem.
• Installing the meter without a gage: (Contact the factory for assistance)
NOTE: For installations with a limited straight run of pipe (less than the recommended
distances shown on pages 9 and 10),adjustments in insertion depth may be needed to
compensate for velocity flow profile variations. Please contact the factory for information on
velocity flow profiling for determining the average velocity location in undeveloped flow
locations.
3.4 REMOVAL OF THE METER
***CAUTION***
Remember, the meter may be under high pressure, and while removal of the meter is

basically the reverse of the insertion procedure detailed above, care must be taken to
ensure that the meter is supported against the pipe pressure before the position
clamping nut is loosened. Failure to do this will allow the pressure to suddenly and
rapidly force the meter from the pipe causing serious injury.
Prior to removal of the meter, make sure that you are standing on a secure platform
and have both hands available to manipulate the flow meter.
Owner’s Manual for ONICON Insertion Turbine Flow Meters • September 27, 2001
12
Page 14
First support the flow meter against the pipe pressure by holding
the electronics enclosure firmly in hand BEFORE loosening the
position clamping nut. The effort which will be required is the
same as that required for insertion of the meter and should be
calculated according to the formula in the prior section covering
insertion of the meter. This effort will be 0.11 times the pipe
pressure. If your footing is not secure, or if your ability to hold
the meter limited for any reason, DO NOT loosen the clamping
nut.
SLOWLY loosen the position clamping nut and carefully and
slowly allow the pressure to force the meter out of the pipe. This
is not at all difficult, but you must not let go of the meter until it
is fully withdrawn into the hot tap adapter. After the meter is
completely withdrawn, you may close the isolation ball valve.
The main cause of damage to meters comes from accidentally closing the valve on the turbine
assembly. To avoid this, gently rotate the meter by twisting the electronics enclosure back
and forth (twist the stem, do not bend it) while you slowly close the valve. If the valve
touches any part of the meter, you will feel it as you are twisting the meter. If the valve
touches anything, it means the meter is not fully withdrawn. Usually a gentle twisting motion
while withdrawing the meter will clear any obstruction and permit the meter to withdraw
completely. (Excessive build-up on the stem may require the hot tap ‘O’ ring to be lubricated
with silicone.)
!
!
After the valve is completely closed, you can safely unscrew the hot tap adapter from the
valve. Partially unscrew the adapter and allow pressure to vent from the hot tap adapter.
There will be very little water in the hot tap adapter; however, a small bucket or pan should
be held under the valve to catch any spilled water.
***CAUTION***
In hot water systems, even a small amount of water can cause serious personal
injury. Use extra caution when working with hot water meters.
3.5 ADJUSTMENT OF THE METER
***CAUTION***
If adjustment of the meter depth is required, the same procedure must be followed as
if the meter was being removed. Please carefully read the section above on removal
of the meter. Remember, the meter may be under high pressure and failure to follow
the procedure may result in serious injury.
Once the meter has been moved to its new depth, tighten the position clamping nut. Next,
place several turns of electrical tape around the stem just above the clamping nut so that at a
later time, when the meter is removed for service, it can be easily replaced at the same depth.

3.6 WIRING CONNECTIONS
Make connections to the 10’ cable, which is supplied by ONICON and is pre-wired to the
circuit board.
Do not attempt to make any connections inside the electronics case, or to remove
factory installed connection fittings. Damage resulting from these actions may
not be covered under warranty.
The most common cause of electronic failure is incorrect connection. If you will be adding
any additional cable, please record any substitution of wire colors. If additional cable is
purchased from ONICON, the color code can be maintained. However, cable from other
sources will most likely have a different set of colors. Please refer to Appendix A for wiring
diagrams and factory color codes.
Only qualified service personnel should make connections between the Insertion Flow Meter
and the user’s external equipment. Any misapplication of power and/or ground can result in
improper operation of the unit or damage to the Insertion Flow Meter, the flow meter
circuitry, and to any externally connected equipment.

SECTION 4.0: STARTUP & COMMISSIONING FOR ONICON
INSERTION TURBINE FLOW METERS
4.1 HELPFUL HINTS FOR START-UP AND COMMISSIONING
A step-by step procedure and companion worksheet are located on the next two pages. Please
read all installation instructions carefully before proceeding with installation, start-up and
commissioning.
Please read these helpful hints before proceeding with the start-up and commissioning
procedure on the next page.
1. ONICON Flow Meters are individually calibrated for a particular application. Be sure
to verify the pipe size and location.
2. The electronic sensing systems will not work in air. Blowing on the turbine(s) will
not produce a signal. You can test the meter by holding the turbines under a faucet or
carefully moving it back and forth in a bucket of water.
3. When measuring analog output signals, remember that currents (mA) must be
measured in series, while voltages are measured in parallel. If the 4-20 mA signal is
already connected to a control system, you must break the connection and measure
the signal in series.
4. When measuring frequency outputs in hertz, take your multimeter out of “autorange
mode” and manually set range for a voltage level above 15 VDC. This will prevent
false readings when no turbine signal is present.
5. All wiring connections should be made at the end of the factory cable. Do not attempt
to remove the factory installed cable or change the orientation of the electronics
enclosure.
6. Never connect power to analog or frequency output signal wires. ONICON flow
meters are not “loop powered” devices.

Is the meter located in the correct location as required by the plans?
Compare actual straight pipe upstream and downstream of the meter location to recommended
distances identified in the installation manual. Note that the manual is very conservative, assuming
worst-case pipe obstructions; contact ONICON’s technical support department to discuss specifics
of your application. If straight pipe run is very short, consult factory PRIOR to installing a single
turbine meter to discuss possibility of upgrade to a dual turbine meter.
Confirm that the meter is tagged for the pipe size it is installed in. When in doubt, measure the
circumference of the pipe. Pipe O.D. = (circumference / 3.14) – (insulation thickness x 2)
Each flow meter comes with an attached insertion gage and instruction tag. Ensure that meter is
inserted to correct depth and that the electronics enclosure is parallel with the pipe, with the arrow
in the direction of flow.
Confirm that the control system input point is properly configured for the analog range (or binary
scale factor) identified on the flow meter calibration tag & certificate.
Confirm that the flow meter serial number matches the ONICON display or BTU meter serial
number (when ordered together)
Prior to connecting the power, verify that wiring is correct as shown in this manual and/or additional
wiring diagram provided with ONICON display or BTU meter. If in doubt, call factory for assistance
before proceeding further.
Verify that 24 (+/- 4) V is available. Serial Numbers 115692 and later can accept 24 V DC or AC,
but earlier meters required 24 VDC. Note: ONICON display module or BTU Meter provides 24
VDC to the flow meter. ONICON display modules and BTU meters are typically powered by 120
VAC, however, low voltage versions are also available.
Wait approximately 45 seconds after power-on before proceeding further.
The following steps require flow in the pipe. Flow signal readings should be taken while holding the flow rate constant if
possible, otherwise, take the various output readings as quickly as possible.
The average frequency output signal is a 0-15 VDC pulsed output ranging up to 200 Hz and must
be measured with a frequency counter or oscilloscope. Measure DC Frequency (Hz) from
GREEN(+) to BLACK(-). Also measure DC volts on same wires. 5 to 7 VDC is normal for a

GPM = Frequency in Hz X 60
Meter Factor in ppg (refer to calibration tag for meter factor)
For Dual Turbine Models, also measure and record the top and bottom turbine signals
TOP: WHITE(+) to BLACK(-) BOTTOM: ORANGE(+) to BLACK(-)
Refer to flow meter wiring diagram for wire colors for the various outputs available, based on your
particular flow meter model. Use the following formulas to calculate flow rate from measured
analog signals:
GPM = (measured current in mA - 4) X Full Scale Analog Flow Rate
16
GPM = measured DC volts X Full Scale Analog Flow Rate
10
Same calculation as step 9, except use “divided meter factor” (measure and record frequency)
Each contact closure = unit volume identified as “Scale Factor” (measure and record time interval
between contact closures)
The top and bottom turbine frequencies (dual) should be within about 20% of each other and their
average should equal the average frequency output.
Compare the flow rates calculated in STEPS 9 and 10 to each other and to the flow rate indicated
by the control system. Refer to troubleshooting guide when readings are inconsistent.

REPORTED PROBLEM POSSIBLE SOLUTIONS
• Verify that meter is inserted correctly into the pipe.
• Verify that the electronics enclosure is parallel with the pipe.
No Signal
Reading is too high or too low
• Verify 24 V supply voltage.
• Verify correct wiring to control system (see wiring diagram).
• Check turbine(s) for debris.
• Verify pipe size. Contact factory if pipe size is different from calibration tag.
• Verify that meter is inserted correctly into the pipe.
• Verify that the electronics enclosure is parallel with the pipe.
• Verify correct wiring to control system (see wiring diagram).
• Confirm that output signals are consistent (frequency vs. analog, etc.)
• Confirm that control system is programmed for correct flow range
or scale factor.
• Check turbine(s) for debris.
Check for ground loop or offset voltage:
• Disconnect analog signal input to control system and measure
Analog signal seems high or
low and does not correspond
to frequency output
analog outputs directly from the flow meter.
• Re-connect signal input to control system and measure the analog
signals again.
• Any difference between these readings indicates a potential ground loop or
offset voltage.
• Please contact ONICON for further assistance.
Control system displays flow
rate, but no flow rate
indication on local display
module or BTU Meter
• Verify that all wires from flow meter were connected to the display
module or BTU Meter.
• The frequency output wire (green) must be connected for any ONICON
Display or BTU Meter.
For technical assistance, contact ONICON Incorporated at (727) 447-6140.

SECTION 5.0: ANALOG ADJUSTMENT PROCEDURE
ONICON electronic circuits are designed and tested to ensure long life with minimal drift;
therefore, you should not expect to make regular field adjustments or calibrations. However,
it will be necessary for you to rescale the analog output under the following conditions:
• The turbine was replaced with a new one having a significantly different
meter factor.
• You wish to change the flow rate represented by the analog output.
• An analog output meter is being moved to a different size pipe.
ONICON will do all of these recalibrations at low cost, with a one or two day turnaround.
However, we have included this section for those instances where you cannot return the
meter or simply want to do the work yourself. We will be happy to work through the
procedure with you on the phone, if you desire.
While these adjustments are not complicated, they are crucial to the accuracy of the flow
meter. Therefore, any adjustments should be made only by qualified personnel having an
understanding of flow equations and experience with control systems.
5.1 GENERAL DISCUSSION
ONICON Insertion Flow Meters contain circuitry which measures the velocity of a flowing
stream of water, or water based liquid, by sensing the rotational rate of a freely rotating axial
turbine, which is immersed in the flow stream. As each turbine blade passes a fixed
electrode, an electronic pulse is produced by the circuitry. In the case of single turbine
meters, the pulse rate is then calibrated in terms of the number of pulses per gallon in
whatever size pipe the user has selected. This number is called the METER FACTOR. For
example an Insertion Flow Meter might have a meter factor of 31.3 PPG (Pulses Per Gallon) in
3” pipe. This is the calibrated frequency output signal
.
Dual turbine meters are basically the same except that the pulse rates from the upper and
lower turbines are electronically averaged and the calibration is done using this average
output signal.
This frequency output signal can be used directly by some data acquisition systems. Other
systems require an analog representation of flow rate. For these systems the frequency output
signal is processed by the optional analog output card and another calibration is then done on
the 4-20 mA and 0-10 V analog output signal.

5.2 ANALOG ADJUSTMENT PROCEDURE
This procedure adjusts both 4-20 mA & 0-10 V output signals. It is limited to meters with
serial numbers 115692 and higher. Contact the factory for assistance if your meter’s serial
number is below 115692.
5.21 Equipment Required
• Voltmeter
• Pulse Generator
• 24 V Power Supply
5.22 Procedure
1. Determine the input frequency required to simulate the desired maximum
flow rate using the equation below:
Where:
F = Input Frequency (Hz)
R = Maximum Flow Rate (GPM)
MF = Meter Factor* (Pulses Per Gallon)
F = R x MF
60
*The meter factor is written on a calibration tag attached to each meter and is
also recorded on the calibration data sheet. Please contact the factory if you
cannot located the meter factor, or if you wish to use the meter in a different
pipe size.
2. Remove the flow meter from the pipe and make sure the electrode and the
surrounding area are dry.
3. Choose the input frequency range (Hz) from the table on the next page and set
the appropriate range selection jumper. Refer to Appendix A for the internal
wiring diagram of your model.
4. Connect the pulse generator output lead to the test signal input lead on the
analog card, and connect the pulse generator ground lead to the black ground
wire in the flow meter cable. Set the output to a 15 V P-P square wave at the
frequency determined in step #1.
5. Set the DC voltmeter to the 0-10 V scale and connect the (+) lead to the brown
wire in the flow meter cable. Connect the (-) lead from the voltmeter to the
black ground wire in the flow meter cable.
6. Connect the red and black wires in the flow meter cable to the (+) and (-)
terminals of the 24 V power supply respectively. Apply power.
Owner’s Manual for ONICON Insertion Turbine Flow Meters • September 27, 2001

Page 22
7. Adjust the span potentiometer on the analog card to produce a 10 V reading
on the voltmeter.
NOTE: The frequency ranges in the table are a starting point, and since they
vary with electronic component tolerance, it may be necessary to change the
jumper position once rescaling is started. If the range of adjustment of the
span potentiometer is not sufficient to produce the desired 10 VDC, change
the jumper position as follows:
VOLTAGE READING TOO HIGH: Choose the next lower jumper position.
VOLTAGE READING TOO LOW: Choose the next higher jumper position.
8. The flow meter is now rescaled. Disconnect all equipment, replace the cover
and reinstall the flow meter.
