SECTION 3.0: INSTALLATION

3.1 OVERVIEW

Each F-4300 Ultrasonic Flow Meter is provided with a pair of matched ultrasonic transducers.
The transducers are mounted (clamped) on to the outside wall of the pipe. Triaxial cables convey
the transducer signals to the wall mount enclosure containing the signal processing circuitry
and the user interface display. Ultrasonic transducers can be congured to operate in either 4,
2 (Reect) or 1 (Direct) cross operating modes. The choice of operating mode is dictated by the
conguration settings programmed into the meter. For new installations, conguration data is
programmed into the meter prior to shipment. Programming data determines the transducer
operating mode and the spacing between the transducers. This information is provided with the
installation hardware in a document titled, “F-4300 Site Installation Details”.

1 Cross Z or (Direct)

2 Cross V or (Reect)

4 Cross W or (Double Reect)

4 or 2 Cross Mode (Reect)

4 or 2 cross mount is the recommended operating mode whenever possible. It is the simplest way
to mount the transducers. Operating in the reect mode also minimizes the effects of some ow
distortions.

1 Cross Mode (Direct)

1 cross mount provides a shorter sonic beam path. This usually improves performance with
sonically attentive liquids or pipe materials. Direct mounting only requires half the distance
between electrodes when compared to the reect mode and may be the only option if the
availability of mounting space is limited.

3.2 SITE SELECTION

i

Careful attention to the site selection for the system components will help the installers with the
initial installation, reduce start-up problems and make future maintenance easier. For example,
do not install the meter where it will be difcult for personnel to perform periodic maintenance.
When selecting a site for mounting the system components, consider the criteria under Section

1.7 WORKING ENVIRONMENT, as well as the following:

The Wall-Mount Enclosure

Find an easily accessible location where wire connections can be made and meter readings can
be taken from oor level. Mount the enclosure on a vibration-free surface. Avoid sites such as
the plenum of a fan coil, heat exchanger, or other housings containing motors. Avoid mounting
the enclosure in close proximity to VFD’s, electric motors or other strong sources of electrical
interference.

The maximum allowable distance between the wall-mount enclosure and the transducers installed
on the pipe is 100 feet. Only ONICON furnished cable may be used between wall-mount enclosure
and the transducers.

F-4300 Series Clamp-on Ultrasonic Flow Meter Manual 06/17 - 2056-2 / 37515 Page 10

IMPORTANT NOTE

i

The Transducers

For best results, the transducers must be installed on a straight run of pipe, free of bends, tees,
valves, transitions, insertion probes and obstructions of any kind. For most installations, ten
straight unobstructed pipe diameters upstream and ve diameters downstream of the transducers
is the minimum recommended distance for proper operation. Additional considerations are
outlined below.

IMPORTANT NOTE

In some cases, longer straight runs may be necessary where the transducers are placed downstream
from devices which cause unusual ow prole disruptions or swirl; for example, modulating valves
or two elbows in close proximity and out of plane, etc.

Flow

10 Dia.

• Do not, if possible, install the transducers downstream from a throttling valve, a mixing tank,
the discharge of a positive displacement pump or any other equipment that could possibly
aerate the liquid. The best location will be as free as possible from ow disturbances,
vibration, sources of heat, noise, or radiated energy.

• Avoid mounting the transducers on a section of pipe with any external scale. Remove all
scale, rust, loose paint, etc., from the location prior to mounting the transducers.

• Do not mount the transducers on a surface aberration (pipe seam, etc.).

• Do not mount transducers from different ultrasonic ow meters on the same pipe.

• Do not run the transducer triaxial cables in common bundles with cables from other
instrumentation. You can run these cables through a common conduit ONLY if they originate
at the same ow meter.

• Never mount transducers under water.

• Avoid mounting transducers on the top of a horizontal pipe. The best placement on a
horizontal pipe is either the 10:00 or 2:00 position for 4 or 2 cross mode (Reect), or one
sensor at 9:00 and one sensor at 3:00 for 1 cross mode (Direct).

• Do not mount transducers on the bottom of a horizontal pipe.

• Mounting on a vertical pipe is recommended only if ow is in the upward direction. When
mounting on a vertical pipe owing in a downward direction, make sure there is sufcient
back pressure in the system to maintain a full pipe.

This ONICON F-4300 Ultrasonic Flow Meter is a custom calibrated system. Unless specically
noted in writing by ONICON, ALL COMPONENTS (electronics enclosure and matched transducers)
share associated serial number and must be installed together as a system. Mixing components from
different systems will result in signicant errors in calibration.

IMPORTANT NOTE

3.3.1 Mounting the Enclosure

Find an easily accessible location where electrical connections can be made and meter readings can
be taken from the oor level. Mount the enclosure on a vibration-free surface. Avoid sites such as
the plenum of a fan coil, heat exchanger, or other housings containing motors. Avoid mounting the
enclosure in close proximity to VFD’s, electric motors or other strong sources of electrical interference.

Do not drill additional holes in this enclosure. Doing so may damage the electronic circuitry
contained within and will void all warranties.

CAUTION

3.3.2 Preparing the Pipe

Once a suitable section of straight pipe has been located, the pipe surface must be prepared. Refer to the
Site Installation Details document provided with the installation hardware to determine the transducer
spacing dimensions. Prepare the pipe surface as shown below. Clean and de-grease two rectangles where
the transducers will be located. Use sand-paper as necessary to remove any grit, corrosion, rust, loose paint
or other contaminants. The cleaned surface should extend at least ½” beyond the length and width of the
transducers.

Always install hardware at the 10:00 or 2:00 position on horizontal pipes. This prevents the ow meter from
being affect by air trapped at the top of the pipe.

Refer to site installation details
document for transducer spacing.

Prepare mounting
locations for transducers.

For horizontal pipes, locate transducers
at the 10:00 or 2:00 position.

3.3.3 4 or 2 Cross Mode (Reect) Mounting Using Frames and Spacer Bar

1. Prepare the pipe surface as described in section 3.3.2.

2. On a at surface, assemble the hardware as shown in the drawing below.

Orient mounting brackets as shown.

Space bar shows distance

3. Install the mounting straps as shown below. For larger pipes, use multiple straps connected end-to-end
to increase the length of each strap. Leave enough slack in the straps to allow the assembly to be
correctly positioned on the pipe. The location of the routing hole allows for the straps to mount outside
of the pipe insulation, if the pipe is insulated.

Refer to the Site Installation Details document provided with the
installation hardware to determine the correct separation distance.

Routing Holes

4. Move the hardware assembly to its nal position on the pipe. Align the brackets with the prepared surface
for each transducer, ensuring that the entire assembly is properly oriented along the axis of the pipe.
Tighten the assembly rmly on the pipe. Do not over tighten the straps.

3.3.4 1 Cross Mode (Direct) Mounting Using Brackets and Spacer Bar

i

1. Once the installation site selection process described in section 3.2 is complete, prepare the pipe where
the rst sensor will be mounted.

IMPORTANT NOTE

1 Cross mode mounting requires that transducers be installed on opposite sides of the pipe. For
horizontal pipes, the transducers should be located at the 3 o’clock and 9 o’clock positions.

2. To prepare the pipe, temporarily position a mounting bracket on the pipe where you will be mounting it.
Ensure that the pipe surface is smooth without any raised areas (seams, etc.) With a pencil, marker or chalk,
draw a generous rectangle around the bracket. Clean and de-grease the area within the rectangle. Use the
small sanding block provided with the installation hardware as necessary to remove any grit, corrosion, rust,
loose paint or other contaminants. Be sure to wipe the surface clean
after sanding. The cleaned surface should extend at least ½” beyond
the length and width of the mounting bracket.

3. Attach the spacer bar to one of the mounting brackets at the reference mark on the ruler.

4. Position the mounting bracket and spacer bar in the center of the cleaned
area and secure it in place with a mounting strap as shown below. Make sure
the mounting strap tightening screw is facing up. While tightening the strap,
check to ensure that the bracket remains centered on the pipe. (The bracket is
centered on the pipe when the bottom edges of both stainless side plates on
the bracket are in full contact with the pipe surface.)

5. Attach the second bracket to the spacer bar at the separation distance specied on the site installation
details document provided with the installation hardware.

Orient mounting brackets as shown.

Reference Hole

6. Check to ensure that this bracket is lined up on the center of the pipe. While holding the bracket centered on
the pipe, place a mark (with pencil or chalk) at the center of the bottom of the bracket as shown below. Next,
mark along the edge of the bracket as indicated in the drawing below.

Place mark at center
of bracket roller.

7. Remove the bracket from the spacer bar and then remove the spacer bar from the bracket that is strapped
to the pipe. Using the spacer bar as a straight edge, draw a line down the center of the pipe intersecting the
mark made at the center of the tapered roller and the line drawn against the edge of the bracket as shown
below.

Spacer bar

Draw line using spacer bar as edge.

8. Wrap a spacing guide (could be a wire, hose clamp) around the pipe so that the left edge is against the

transducer edge mark. Arrange so that one end overlaps the other. Ensure that it is snug around the pipe and
mark along the overlapping edge.

Spacing guide

Draw the guide tightly
around the pipe and mark
at the overlapping edge.

9. Remove the spacing guide and lay it out on a at surface. Either measure the exact distance half-way
between the overlap edge and the mark at the overlap, or fold the guide from the overlap edge to overlap
mark and draw a line at the fold or halfway point.

10. Reinstall the spacing guide; its edge abutting the bracket edge mark on the pipe and the overlapping edge
in line with the line drawn down the center of the pipe. Tape it in this position on the pipe. Take the
second bracket and place it against the edge of the guide with it centered on the half way mark drawn on
the guide.

11. Ensure that the bracket is sitting on a smooth area without any
raised spots (seams, etc.). Mark a generous rectangle around the
bracket with a pencil, marker or chalk. Remove the bracket and the
spacing guide.

12. Clean and de-grease the area within the rectangle. Use the
small sanding block provided with the installation hardware as
necessary to remove any grit, corrosion, rust, loose paint or other
contaminants. The cleaned surface should extend at least ½”
beyond the length and width of the mounting bracket.

13. Replace the spacing guide back in the same position it was in and re-tape it to the pipe.

14. Position the bracket as before against the edge of the guide with the center of the bracket centered on the
half way mark drawn on the guide. Secure it in place with a mounting strap. Make sure the mounting strap
tightening screw is facing toward the bracket so you can hold it in place while tightening the screw. While
tightening the strap, check to ensure that the bracket remains centered on the pipe. (The bracket is centered
on the pipe when the bottom edges of both stainless steel side plates on the bracket are in full contact with
the pipe surface.)

3.3.5 Installing Transducers In Bracket and Spacer Bar Hardware

1. Apply the coupling to the transducer as show below. A packet of Super Lube was supplied with
the transducers. Contact ONICON if you need more compound.

Apply a continuous lengthwise ¼” wide bead of coupling
compound down the center of the transducer.

2. Slide the transducer into the mounting bracket. Do not allow the bottom of the transducer to make
contact with the pipe until it butts against the mounting bracket. The clamping bracket can be
retracted such that the transducer cam be directly over the correct position before making contact
with the pipe. Push down rmly on the transducer to mate with pipe.

When installing the transducer, do not allow
the bottom face to touch the pipe surface
until it is fully inserted to the bracket.

3. Tighten the transducer clamping screw to hold the transducer rmly in place. Do not over
tighten the screw. If you are not routing exible conduit all the way to the mounting bracket,
you can remove the conduit adapters to make installation easier.

4. Connect transducer cable female BNC to transducer male BNC. Slide
the protective rubber boot over the transducer’s BNC connector. In
environments where condensation may occur (Chilled water systems),
apply a generous amount of Super Lube dielectric grease inside the
boot before sliding it over the BNC connector.

5. Repeat procedure for the second transducer.

SECTION 4.0: START-UP

ONICON F-4300 ow meters are normally shipped with the intended installation parameters pre­programmed into the memory of the meter. This pre-programmed site is based on installation data
provided to ONICON when the meter was ordered. The information programmed into the meter is
also provided in a document that accompanies the installation hardware. It is titled, “Site Installation
Details”.

If the information contained in the Site Installation Details document matches that specic installation
location, then after the transducers are installed, connected, and powered on, the meter should
establish a ow reading on its own. If there is any discrepancy between programmed parameters and
actual site conditions, then the programming for the site must be edited before it is used. This manual
contains information on programming the meter in the eld, but if you require any assistance, please
contact ONICON for assistance.

ft3/m (cubic feet per minute)

Temperature – Select units for temperature domain.

Options: F (Degrees Fahrenheit), C (Degrees Celsius)

Setup Menu Page

The Setup page allows the user to dene the type of transducer used, and to dene process
conditions like pipe material & size, and uid type & temperature. After these settings are dened,
the spacing distance will be displayed on this page, and once the transducers are installed the
meter will be ready to work.

All of these settings are pre-congured by ONICON before shipment. These settings should only
be adjusted if the process conditions provided to ONICON at time of order were incorrect, or
different transducers were supplied for eld installation.

Sensor Select – SE16B is the only option available at this time.

Angle – Select the angle of the transducer. Contact ONICON for assistance dening what angle

sensors you have.

Fluid – Select between Water or Other. When Water is selected, the speed of sound of the uid is
determined based on the temperature entered later in this Setup menu.

F-4300 Series Clamp-on Ultrasonic Flow Meter Manual 06/17 - 2056-2 / 37515 Page 26

Vel@25C – Only appears if “Other” was selected at the Fluid option. Enter the speed of sound of
the uid at 25°C (77°F). Units are dened by what was selected in the Units/Mode menu.

dV/C – Only appears if “Other” was selected at the Fluid option. This denes how much the
speed of sound varies per degree C. This should be left at 0 unless the speed of sound change of
the uid is linear with respect to temperature.

Temp Mode – Should be left at “Fixed”

Temp – Temperature of the uid. If “Water” was selected at

Fluid, enter the water temperature. If “Other” was selected
at Fluid, enter 25.0C or 77.0F for the uid temperature,
depending on units of measurement selected.

Pipe – Select the pipe material.

Options: Carbon Steel, Brass, Aluminum, Acrylic, ABS, Other,
Stainless 430, Stainless 410, Stainless 347, Stainless 316, Stainless 304, Stainless 303, Stainless
302, Mild Steel, PVC, Poly HD, Poly LD, Nylon, Iron, FRP, Ductile Iron, CPVC, Copper, Cast Iron.

Vel – If “Other” pipe material was chosen, enter the sonic velocity of the pipe material here.
Units of measurement are dened in the Setup menu.

OD – Enter the pipe’s outside diameter in units dened in the Setup menu. Charts with
standard pipe sizes based on schedule are provided in the appendix of this manual.

Wall – Enter the pipe’s wall thickness in units dened in the Setup menu. Charts with
standard pipe sizes based on schedule are provided in the appendix of this manual.

Lining – Select whether or not the pipe the meter is being mounted to has a liner.
Options: None, Tar Epoxy, Rubber, Mortar, Asb Cement, Other

Thick - Enter the liner thickness in units dened in the Setup menu. Only appears if Lining is
not “None”

Crossings – Denes the number of times the ultrasonic signal
crosses the inside of the pipe. The rst choice used should be 2 or 4
crosses.

1 crossing is a “Z” or “Direct” mode, 2 crossings is a “V” or
“Reect” mode, and 4 crossings is a “W” or “Double Reect” mode.
1 crossing will provide the largest signal strength but more diligence
is required to mount the transducers properly.

2 crossings provide the easiest means to mount the transducers,
averages some of the ow distortions in the pipe, but attenuates
the signal more than 1 cross. This is the default and ONICON
recommended conguration.

4 crossings provide even more averaging than 2 crosses. 4 crosses
will not be an option unless the transducers overlap in a 2 cross
setup, which is dependent on pipe settings and uid sonic velocity.

Zero Tare – Used to suppress readings or uctuations at zero ow.
Do not enable this function unless ow in the pipe has been valved to 0, and the pipe is full.

Sens Space – This function is not editable. This value will automatically calculate after the
sensor type, angle, uid type and temperature, pipe material and size, and number of crossings
is dened. This distance is dened as the measurement between the inside of both transducers.
Because the meter comes pre-programmed from ONICON, this number is already dened for you
on the “Site Installation Details” sheet. However, if any of the factors listed above is changed in
the eld, you will need to change the transducer spacing to the new number provided here.

F-4300 Series Clamp-on Ultrasonic Flow Meter Manual 06/17 - 2056-2 / 37515 Page 27

Velocity – After mounting the transducers and connecting the transducer cable, you will be able to
see the ow velocity in real-time once ow is established.
Signal Strength – After mounting the transducers and connecting the transducer cable, you will
be able to see the signal strength in real-time. The pipe must be full of water to get a valid signal
strength reading.

Calibration Menu Page

The calibration menu denes the behavior of the ow measurement
and its related outputs.

Mode – Shows the Mode which was selected in the Units/Mode
menu. Could be “Flow” or “Velocity.”

20 mA at or 5V at – Enter the desired ow rate to be equal to 20
mA or 5V.

4 mA at or 0V at – Enter the desired ow rate to be equal to 4 mA
or 0V. Typically, 0 ow/velocity, but could be a negative value if
you wanted the 4-20 mA/0-5V output to represent more than one direction.

Min Flow – Value which if the measured ow rate falls below, the meter will force the reading and
outputs to 0. Units match those congured in the Units/Mode menu. The default and recommended
value is the volumetric ow rate equivalent to 0.1 ft/sec in your pipe size.

Damping – The damping value stabilizes the ow rate on the display and analog output. For
applications with poor straight run, use a higher dampening value to steady the ow reading. Lower
dampening values should be used in applications where you want a faster response from the meter.
The default dampening value is 20%.

Cal Constant – Calibration constant dened during calibration. This value shouldn’t be changed
unless ONICON support has requested to do so.

Relay Parameters Menu Page

The relay parameters page is where changes can be made to the
pulse outputs available with the F-4300

Relay – Denes which pulse output you are making changes to,
either 1 or 2.

Function – Denes the behavior of the pulse output selected at the
Relay option. Choices:

On – Pulse is always engaged

Off – Pulse is always disengaged

Pulse – Scaled pulse. Dene how many gallons must be
measured before a pulse occurs.

Pulse duration = 50 ms; max Hz = 10

Logging

The Data Logging page allows conguration of the data logger. Options include what is being logged,
how often it is being logged, and the date settings.

Log Site ID – Provide a number to the log site you’re creating. Can be any number between 00-99.

Mode – Dene what is being logged. Options: Flow, Velocity.

File Format – Dene how you will want the data presented when downloaded. Choose .LG2 when

you will be looking at the log data with the ONICON Logger Utility software. Choose .CSV when you
will be loading the data directly into an Excel spreadsheet for manipulation and graphing.

Date – Congure today’s date. Format: Month Day/Year.

Time – Congure the time. Format: hh:mm:ss. Range: 00:00:00-23:59:59.

Interval – Dene how often the unit selected under Mode will log.

Options: 10 sec, 30 sec, 1 min, 2 min, 5 min, 10 min, 15 min, 30 min,
and 60 min.

At the fastest interval, 10 sec, the logger will last 8.5 years before it is
full. However, if you are curious about the % log used, it is available in

the Messages Menu accessible from the Run Screen by pressing the

Flow – Pulse output functions as a ow alarm. You will need to dene when the alarm comes
ON, and when the alarm will turn OFF again.

Examples:

High Flow Alarm: ON = 300 GPM, OFF = 250 GPM

Flow goes above 300 GPM and the pulse output latches ON. It will not turn OFF until ow
goes below 250 GPM.

Direction Switch: ON = +0.1 GPM, OFF = -0.1 GPM

Any ow above 0.1 GPM will cause the pulse to turn ON, and it will turn off should ow reverse.

The logger must be congured in a specic order in order to function correctly:

1. Set the Log Site ID, Mode, File Format, Date, Time, and Interval to the desired option.

2. Under Data Log, select “Delete”

3. Under Data Log, select “Start”
Deploying the logger in any other order will compromise the settings you’ve chosen.

The communications menu allows provides the means to select the
serial output of the meter, and the addressing and communication
speed.

Protocol – Select the protocol for the serial communications. Options:
BACnet, OFF

DevID – Only available if BACnet was the selected Protocol. This is the Device ID which must be
unique for the device across the whole BACnet network. Range: 0-4,194,302.

MAC Address – Only available if BACnet was the selected Protocol. This is the RS485 bus address
for the BACnet MS/TP communications. Range: 0-127 for master devices, 128-254 for slave devices.

BPS – BAUD Rate, or bits per second. Denes the speed of communication on the BUS. Must be the
same for all devices on the BUS. Options: 9600, 19200, 38400, 76800.

Special Functions Menu Page

Language – Select the language for the menus and display. Options: English, French, Spanish.

Analog Out – Denes the analog output type. Options: 4-20 mA, 0-5V.

Backlight – Raise or lower the brightness of the display backlight. Options: Off, High, Med, Low, Key Hi/

Lo (Brightness goes to High after a keypress, then Low after 1 minute of no button presses), Key High,
Key Med, and Key Low (Brightness goes to specied value after keypress, then OFF after 1 minute).

Reset Totalizer – Select YES to reset totalizer. YES will ash two times after pressing

to

indicate the action was accepted.

Neg. Totals – Selecting NO will cause the totalizer to ignore ow
rates in the negative direction. Only positive ows will accumulate
the totalizer. Selecting YES will cause negative ows to deduct from
the totalizer. Totalizer values can achieve a negative value if negative
totals are greater than positive totals.

Restore Defaults – Selecting YES will cause all of the program­ming settings to revert to the factory default. These defaults are
different than the programming ONICON performed at the factory
before the meter was shipped.

New Password – This function allows a new password to be set. This password protects the
programming menu access from the Main Display. The default value is 0000. Range: 0000-9999. Do not
lose the password if changed, in case you need to return to the programming menu at a later date.

Simulation Menu Page

The simulation menu page is used to generate ow rates independent of the actual measurement in
the system, in order to test output signals.

Any simulated ow rate is only active while the Simulation Menu is open. Once the menu is exited,
the ow rate and output signal behavior will return to that actually measured by the meter.

Test – This function denes how the simulation mode will be tested. Options: Actual, Maximum,
Minimum.

When Actual is selected, any ow rate which is currently present will be displayed on the screen,
and the outputs associated with that ow rate is also displayed. Alternatively, you can move the

cursor to the Flow option, press

set a ow rate manually. After

to enter the option, and then

is pressed, the analog output

and pulse outputs will be driven by the set ow rate.

When Maximum is selected, the ow rate will be driven to the 20
mA/5V value congured in the Calibration Menu Page.

When Minimum is selected, the ow rate will be driven to the 4 mA/0V value congured in the
Calibration Menu Page.

SECTION 7.0: COMMISSIONING FOR ONICON

CLAMP-ON ULTRASONIC FLOW METERS

Please read all installation instructions carefully before proceeding. Wiring diagrams are located in
an earlier section of this manual. Use the meter certicate of calibration to verify that the specied
installation & operating parameters match the actual conditions at the location where the meter is
installed. A worksheet for checking off these steps and recording measured values is located in section

6.3.

7.1 HELPFUL HINTS FOR START-UP AND COMMISSIONING

Please read these helpful hints before proceeding with the commissioning procedure on the next
page.

1. ONICON ow meters are individually calibrated for a particular application. Be sure to verify
the pipe size and location.

2. The ultrasonic ow sensing systems will not work with an empty pipe.

3. When measuring analog output signals, remember that current (mA) must be measured in
series, while voltage is 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.

7.2 COMMISSIONING PROCEDURE

Please read the entire procedure before proceeding. A worksheet for checking off the following
steps and recording measured values provided in Section 5.3.

1. Conrm that the ow meter is
being installed in accordance
with Sections 1.8 and 3.2 of
this manual.

2. Conrm ow meter location. Conrm adequate straight pipe run to achieve desired results. Is the

3. Conrm pipe size. Conrm that the meter is tagged for the pipe size in which it is installed.

4. Verify the type of uid used
in the piping system.

5. Conrm control system
programming.

6. Conrm connection to the
correct ONICON display or
Btu meter (if ordered).

7. Verify output signal wiring. Verify that the wiring is correct as shown in this manual and/or the

8. Conrm correct supply
voltage.

The following steps require ow in the pipe. Flow signal readings should be taken while holding the ow rate
constant, if possible. Otherwise, take the various output readings as quickly as possible.

Conrm that the installation location is removed from any sources of strong
electrical interference and that the enclosure is mounted on a vibration-free
surface.
Conrm that the transducer signal cables are run in dedicated conduit
without other signal or power cables.

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 identied in this manual. Contact ONICON to
discuss specics of your application. If straight pipe run is very short,
consult ONICON PRIOR to commissioning the meter.

When in doubt, measure the circumference of the pipe. Pipe O.D. =
(Circumference / 3.14) – (insulation thickness x 2).

Conrm that the uid specied on the ow meter certicate of calibration
matches the uid owing in the piping system.

Conrm that the control system input points are properly congured for
the analog output range, pulse scale factor and/or relay output function
identied on the calibration certicate & meter tag.

Conrm that the ow meter serial number matches the ONICON display or
Btu meter serial number (when ordered together).

Erratic measurement (set
damping to 0% to check) due
to electrical noise or poor
signal quality.

Variable Speed Drive
interference

Sensor cable connections
incorrect or loose

METER READING LOWER THAN EXPECTED?

Calibration Error • Review calibration menu. Pipe dimensions and uid selection/uid velocity.

Lower ow rate than expected • Investigate pump/valves. Compare velocity with alternate instrument.

Erratic measurement (set
damping to 0% to check) due
to electrical noise or poor
signal quality.

NO ECHO INDICATION Icon: No Echo

Sensor Connections • Ensure triax cable sensor shield is properly grounded.

• Set Calibration / Damping to 5% with zero ow use Setup / Tare function.

• Ensure triax cable shield is properly connected to ground.

• Ensure correct power input ground connection.

• Double-check sensor separation distance and contact ONICON for further
assistance.

• Adjust Calibration Menu / Min Flow setting.

• Follow drive manufacturers wiring and grounding instructions

ensuring that cable is properly inserted into terminals and tightened.

• Ensure triax cable sensor shield is properly grounded.

• Ensure correct power input ground connection.

• Double-check sensor separation distance and contact ONICON for further
assistance.

• Ensure triax cable is connected to transducers.

Sensors not mounted to Pipe
or mounted improperly

Empty pipe or partially lled • Pipe must be uid lled and acoustically transparent in order to obtain echoes.

Coupling compound washed
out, or sensor loose on pipe.

METER READING HIGHER THAN EXPECTED?

Calibration Error • Review calibration menu. Pipe dimensions and uid selection/uid velocity.

Higher ow rate than
expected

Erratic measurement (set
damping to 0% to check) due
to electrical noise or poor
signal quality.

Pipe not Full • Verify pipe is full by mounting sensors at top of pipe and check echo icon. No

• Apply coupling compound and mount sensors to pipe with proper sensor
spacing.

• Remount sensor

• Use Super Lube ultrasonic couplant.

• Investigate pump/valves. Compare velocity with alternate instrument.

• Ensure triax cable sensor shield is properly grounded.
