SECTION 1.0: INTRODUCTION

!

We, at ONICON Incorporated, would like to thank you for purchasing our quality American made
F-5200 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-5200 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.

WARNING

This ow meter may be installed in pipes which are under high pressure or pipes lled with
combustible gases. Accidents with these systems can cause serious injury or death. Only persons
experienced with high pressure and/or combustible gas distribution systems and uid metering
should attempt to install, adjust, or remove the ow meter. Please read all instructions carefully
before attempting to install or service a ow meter.

ONICON will be happy to assist with technical recommendations and to provide guidance by phone
or e-mail. On-site eld engineering, installation and service are also available at an additional cost.

3.1 INSTALLATION SITE SELECTION

Install the ow meter where it will be accessible for personnel to perform necessary periodic
maintenance. The clearance required for installation is a minimum of 9” from the pipe wall
to the nearest obstruction above the electronics enclosure. Refer to Section 1.5 WORKING
ENVIRONMENT for additional considerations.

ONICON insertion style ow meters must also be correctly oriented in the pipe with respect to
the direction of ow.

The drawings below illustrate the relationship between ow direction and the orientation of the
meter when installed in the pipe. Contact ONICON for assistance if this relationship does not
allow for proper installation.

2. Straight run requirements vary based on the nature of the upstream obstruction.
See the table on page 10 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.

F-5200 Inline Thermal Mass Flow Meter Manual 05/14 - 0763-4 / 19476 Page 9

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.

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.

EVALUATING UPSTREAM

In addition to the information provided on the previous page,
the diagrams and the table shown below should be used as a

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.

3.3 ELECTRICAL INSTALLATION

!

!

Make all connections to the attached 10ft cable.

The most common causes of electronic failures are miswired connections during installation.
When adding additional cable, record and carefully document any substitution of wire colors.
Additional cable may be purchased from ONICON that will allow you to maintain the existing
color coding.

All electrical connections to the F-5200 must be made through the 10ft cable provided with the
meter. This cable is not designed to be removed in the eld, and any attempt to do so will
compromise the weather tight integrity of the enclosure.

The cable provided contains 22 AWG color-coded wires for signal and power.

CAUTION

Do not attempt to remove the existing cable or to remove the factory installed connection tting.
Doing so will compromise the weather tight integrity of the enclosure and may void the warranty.

Only qualied personnel should attempt to make electrical connections to the F-5200. Failure
to properly connect the F-5200 power or signal connections may result in damage to the F-5200
and/or to associated peripheral equipment.

3.3.2 Analog Output

The F-5200 is provided with a single 4-20 mA output for instantaneous rate.

Active Output Conguration (Default)
The default conguration for this output is as an active 4-20mA output. In this conguration the
output is electrically isolated from earth, but is common with input power. The blue wire is the
active (+) 4-20mA signal and the brown wire is the (-) 4-20mA return.

Loop Powered Conguration
(Only the output is loop powered, the meter still requires power.)
By changing the position of switch S1 located inside the enclosure, it is possible to loop power
the 4-20mA output. In this conguration the output is electrically isolated from earth and from
input power. In this conguration, an external DC voltage (+) VDC (12 – 24 VDC) is applied to the
yellow wire and the blue wire is the (+) 4-20mA signal. The brown (-) 4-20mA return wire is not
used.

Each 24VDC pulse = unit volume identied as “Scale Factor” (measure and
record time interval between pulses in seconds)

(Pulse interval (in seconds) / 3600) x Pulse weight = Pulse rate

Example: Interval between pulses is 10 seconds and each pulse is equal to 10
SCF. (10/3600) x 10 = 3600 SCFH

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.

• Verify that the meter is properly installed in the pipe.

• Verify that the ow direction arrow is pointing in the right direction.

• Verify correct wiring to control system (see wiring diagram).

• Conrm that the control system is programmed for correct ow range
or pulse scale factor.

• Verify that the meter cable shield is connected to earth at the control
system. Lack of proper shielding can lead to excessive noise that can
affect the ow reading.

• Verify that the meter is connected to earth.

• Check for ground loop or offset voltage:

• Disconnect analog signal input from control system and measure
analog output directly from the ow meter.

• Reconnect signal input to control system and measure the analog
signal again. Any difference between these readings indicates a
potential ground loop or offset voltage.

• Meter is being used to measure ow of a different gas or gas mix than
the meter was specied and calibrated for.
