SECTION 1.0: INTRODUCTION
We, at ONICON Incorporated, would like to thank you for purchasing our quality American made
F-5100 Series Thermal Mass Flow Meter. As our valued customer, our commitment to you is to
provide fast reliable service, while continuing to offer you quality products to meet your growing
ow measurement needs.
1.1 PURPOSE OF THIS GUIDE
We have written this guide to provide the persons responsible for the installation, operation and
maintenance of your ow meter with the product specic information they will need. This is
NOT an electrical or plumbing trade manual.
WARNING
Please do not permit persons to install, operate or maintain this equipment unless they have a
complete knowledge of their trade skills and are competent to work on combustible gas and/or high
pressure compressed air systems, according to their individual trades. Death or permanent injury
may result from accidents with these systems.
!
This guide is the basic reference tool for all ONICON F-5100 Inline Thermal Mass Flow Meters.
If you have not purchased all of the options, there will be references in this manual which are not
applicable to your meter(s).
1.2 TYPICAL INLINE THERMAL MASS FLOW METER
Each ONICON thermal mass meter has a single pair of encapsulated platinum sensors that are
in direct contact with the gas. The sensors consist of highly stable reference-grade platinum
windings. One sensor is self-heated and serves as the ow sensor. The other acts as a reference
sensor, and measures the gas temperature. Our proprietary sensor circuitry maintains a constant
temperature differential between the ow sensor and the reference sensor.
As gas ows by the heated sensor (ow sensor), the molecules of owing gas carry heat away
and the sensor cools. The sensor circuitry continuously compensates for this cooling effect and
maintains a constant temperature differential between the two sensors. The energy required to
maintain this temperature differential is directly proportional to the mass ow. There is no need
for additional temperature or pressure compensation.

How to Determine the Available Straight Pipe Run:
Locate the longest straight unobstructed section of pipe available. To be unobstructed, the
section of pipe must be free of bends, tees, size transitions, valves or insertion probes of
any kind.
In addition to the information provided above
and on the previous page, the diagrams
shown below and the table shown on the next
page should be used as a guide to identifying
the best installation location for the meter.
Required upstream/downstream distances in inches
as measured from the process
connections.
GENERAL PRACTICES:
1. For best results, install the ow meter in a straight run of pipe, free of bends, tees,
valves, transitions and obstructions.
2. Straight run requirements vary based on the nature of the upstream obstruction.
See the table on page 12 for guidelines in determining upstream straight run
requirements. Depending upon specic location details, more or less straight run
may be required to produce a satisfactory ow prole.
3. If there is insufcient straight run, allow 80% of the run upstream and 20% of
the run downstream. If the total length of straight run is less than 75% of the
recommended distance, performance may seriously degrade.

IMPORTANT NOTICE
Always use the maximum available straight run. When more than the minimum required straight
run is available place the meter such that the excess straight run is upstream of the meter location.
The ow meter must also be properly installed with respect to the direction of ow. Installing the
meter with the ow arrow pointing in the wrong direction will result in signicant errors in the
ow measurement.

Installation Instructions
1. Thoroughly clean all ange surfaces removing all traces of any old gasket material
or any adhesive residue.
2. Inspect all ange surfaces for warping, pitting or other surface imperfections that
may prevent a good seal.
3. Use new bolts, nuts and hardened washers. Prior to installation,
lubricate the bolt threads, nuts, washer faces and the underside of each bolt head
with lubricant (Fel Pro C5A or equivalent). This lubricant is necessary to ensure
uniform stress distribution on the sealing surface. Use care not to get any
lubricant on the gasket material.
4. Center the new gasket on the ange face. Do not allow the gaskets to protrude into
the ow stream.
5. Use the torque specications provided by the gasket manufacturer to determine
the proper torque setting.
6. Using a torque wrench, tighten the bolts in at least three stages (30%, 60% &
100%) using a repeating pattern sequence of 12 o’clock to 6 o’clock to 3 o’clock to
9 o’clock around the ange as shown in the diagrams below.
7. Leak test all connections.

SECTION 4.0: START-UP & COMMISSIONING FOR ONICON
INLINE THERMAL MASS FLOW METERS
4.1 DISPLAY
The F-5100 ow meter features a bright easy-to-read
graphic LED display that displays alphanumeric and
graphical data.
This display is provided with a screen saver function
that extends the life of the display. The display will
revert to the normal display mode whenever the
proximity sensor detects movement directly in front
of the meter.
Displayed Information:
1. Energy reading used to valid calibration
2. Graphical indication of percentage of full
scale ow rate
3. Flow rate
4. Flow total
5. Fluid temperature
6. Engineering units associated with ow rate and total
7. LED’s for Power, Serial Communications, and Pulse Output
4.2 POWERING THE METER
Upon initial power up, the meter will indicate ONICON F-5000 Series along with the current
rmware version and the serial number. Two additional messages will be displayed and then the
meter will advance to the normal run mode screen. If the meter is installed in a pipe with ow,
the meter will begin displaying ow and temperature data. After one minute of no movement,
the screen saver message will appear.
4.3 HELPFUL HINTS FOR START-UP & 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 start-up and commissioning.
Please read these helpful hints before proceeding with the start-up and commissioning procedure
on the next page.
1. 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.
2. Do not attempt to rotate the electronics enclosure on the stem.
3. Never connect power to analog or pulse output signal wires. Standard ONICON F-5100
Flow Meters are not congured from the factory as “loop powered” devices.

4.4 START-UP & COMMISSIONING
Please read the entire procedure before proceeding. A worksheet for checking off the following
steps and recording measured values is located on the next page.
1. Conrm ow meter location.
Conrm adequate straight pipe run
to achieve desired results.
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 identied in this manual.
2. Conrm orientation. Refer to the information in section 3.1 of this manual to ensure
that the meter is properly oriented with respect to the direction of ow.
3. Conrm control system
programming.
Conrm that the control system input point is properly congured for
the analog range and/or scale factor identied on the calibration tag
& certicate.
4. Conrm connection to
correct ONICON display
Conrm that the ow meter serial number matches the ONICON
display (when ordered together).
5. Verify wiring before connecting
power.
Prior to connecting the power, verify that the wiring is correct as shown
in this manual and/or on additional wiring diagrams provided with the
ONICON display. If in doubt, contact ONICON for assistance before
proceeding further.
6. Conrm correct supply voltage. Verify that the supply voltage matches the voltage listed on the meter
tag.
7. Connect power. Wait approximately 45 seconds after power-on before proceeding
further.
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.
8. Measure and record analog and
pulse outputs.
Current Output:
Scaled Output:
Refer to ow meter wiring diagram to locate the correct output
terminals. Use the following formula to calculate the ow rate from
the analog signal measurement:
SCFM = (measured current in mA - 4) X Full Scale Flow Rate
16
Each 24VDC pulse = unit volume identied as “Scale Factor” (measure
and record time interval between pulses)
9. Compare output signals to each
other and to the ow rate displayed
by the control system.
Compare the ow rate calculated in step 8 to the ow rate indicated
by the control system. Conrm that the control system is registering
scaled output pulses as they occur.
Refer to troubleshooting guide when readings are inconsistent.
