1.2 PRINICPLE OF OPERATION
The operating principles of ONICON F-3200 Inline Electromagnetic Flow Meters are based on
Faraday’s Law of Electromagnetic Induction. Faraday’s Law states that a voltage will be induced
in a conductor (water or other conductive liquid) when it passes through a magnetic eld
(generated by the meter), and the induced voltage will be directly proportional to the velocity of
the conductor. By placing electrodes on opposite sides of the ow tube, it is possible to accurately
measure the induced voltage and determine the corresponding velocity of the owing liquid.
WARNING
Only qualied service personnel should attempt to install or service this product. Serious injury may
result from the improper installation or use of this product.
1.3 TYPICAL FLOW METER INSTALLATION
ONICON’S F-3200 Inline Electromagnetic Flow Meters are suitable for volumetric ow
measurement of electrically conductive liquids in a wide variety of applications including
bi-directional applications.
• Two programmable open collector pulse outputs. Outputs may be programmed to provide:
* an indication of ow direction
* a scaled pulse for totalizing ow
* a high resolution frequency output to drive peripheral devices
* an indication of an alarm condition
Flow meters are wet calibrated in a ow laboratory
against standards that are directly traceable to
government standards. A certicate of calibration
accompanies every meter.

Note: Specications are subject to change without notice.
Grounding rings may be required whenever meters are installed in non-metallic or lined
pipes. Grounding rings placed before and after the meter eliminates electrical noise that
will interfere with the proper operation of the meter. ONICON provides grounding rings
as an optional accessory. Grounding ring dimensional information and part numbers are
listed below. For proper operation, grounding rings are required before and after the meter.
Gaskets are required for sensor bodies with ebonite and polypropylene liners and are
strongly recommended for meters with PTFE liners. Gasket dimensions must comply with
ASME B16.5 ange standards. ONICON is not a gasket manufacturer and does not supply
gaskets for this product.
The following general suggestions are provided to assist the installer in choosing the
proper gasket material. In all cases, the responsibility of selecting the appropriate material
rests with the installer.
Gaskets are used to create a seal between the ow meter liner surface and the surface
of the mating ange. The proper choice of gasket material will allow for a leak free
connection at the time of installation and maintain that seal over time. How well the
gasket works depends on a number of factors. Each of these should be considered when
choosing a gasket material.
• Is it chemically compatible with the uid?
• Will it withstand the expected minimum and maximum operating temperatures?
• Does it provide enough resiliency and creep resistance to maintain loading over time?
• Will it deform enough to create a seal by lling imperfections in the sealing surfaces?
• Is it thick enough to take up variations in atness of the surface?
In many cases a simple 1/8” red rubber gasket with a Shore A hardness (Durometer) of
60 – 80 will sufce. Your local gasket supplier should be able to guide you in selecting the
best material for your application.
1.6 WORKING ENVIRONMENT
The F-3200 was designed for installation and use in typical industrial environments that are free
of corrosive liquids and fumes, direct liquid exposure, direct sunlight, temperature extremes and
vibrations.
The operating ambient air temperature range is -4° F to 140° F.
The electrical power should be relatively clean, free of high frequency noise, large voltage
transients, and protected from power surges and brown outs.
1.7 WARRANTY & SERIAL NUMBER
Warranty
ONICON’s complete warranty is included the “Conditions of Sale”. ONICON provides a
two-year warranty.
Serial Number
The F-3200 has 2 separate serial numbers. The transmitter serial number is located on
the identication plate located on the electronics enclosure. The sensor serial number is
located on the identication plate located on the sensor body.
The F-3200 is generally shipped in one package unless optional hardware or equipment is ordered.
Notify the freight carrier (all products are shipped insured) and ONICON if any items are damaged in
transit.
2.1 CHECKING THAT YOU HAVE RECEIVED EVERYTHING
• Standard Documentation
Enclosed with each F-3200 is a comprehensive documentation package that includes
the following items:
The F-3200 Installation and Operation Guide
Certiat of Calibration
Please notify ONICON if any of these items are missing.
F-3200 inline magnetic ow meters with integrally mounted transmitters are shipped fully assembled. Remove the meter from the shipping carton and inspect it for physical damage.
• Remote Mount Transmitter
F-3200 inline magnetic ow meters ordered with the remote transmitter mounting option will be provided in one carton that contains the ow sensor body, the transmitter with mounting
hardware and the necessary cable to connect the two together. Remove each and inspect it for
physical damage.
IMPORTANT NOTE
F-3200 transmitters and sensor bodies are two parts of one uniquely calibrated system and must be
installed together. Mixing components from other systems will result in signicant calibration errors.
• Grounding Rings
Grounding rings are optional accessories that may be required for proper installation.
Grounding rings may be shipped in a separate carton. Remove each and inspect it for
physical damage.
SECTION 3.0: INSTALLATION
The F-3200 Inline Electromagnetic Flow Meter should be installed by experienced plumbers,
electricians and others with related knowledge and experience in the heating, cooling, and uid
metering elds. ONICON will be happy to assist with technical recommendations and to provide
guidance by telephone and/or email. On-site eld engineering, installation and service are also
available at an additional cost.
The installer should use good trade practices and must adhere to all state and local building or other
applicable codes.
3.1 SITE SELECTION
Careful attention during the site selection process will help the installers with the initial
installation, reduce start-up problems, and make future maintenance easier. For example, do not
install the ow meter where it will be difcult for personnel to perform periodic maintenance.
When selecting a site for mounting, consider the criteria under Section 1.6, WORKING
ENVIRONMENT, as well as the following:
IMPORTANT NOTE
Proper site selection is critical to the performance of this ow meter. The ow meter must be
properly located within the piping system in order to ensure an accurate ow measurement.
