This guide is the basic reference tool for all ONICON FB-3500 Bi-Directional Electromagnetic

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 INSERTION ELECTROMAGNETIC FLOW METER

Faraday’s Law of electromagnetic induction states that a voltage will be induced in a conductor

when it passes through a magnetic eld, and the induced voltage will be directly proportional to

the velocity of the conductor.

ONICON FB-3500 Bi-Directional Electromagnetic Flow Meters generate pulsating magnetic elds

that are used to induce a voltage into the conductive uid owing through the pipe. Electrodes

located on the ow meter sensor head measure the induced voltage. Circuitry within the ow

meter electronics enclosure then converts the voltage to digital and analog signals that convey

ow rate and total data via connecting the cable to any of ONICON’s display devices, Btu meters

and/or to a data acquisition system.

1.4 ADDITIONAL REQUIRED HARDWARE

All ONICON insertion type meters can be installed and removed via

a 1” or larger full port ball valve without system shutdown. The

terms “Standard” and “Hot Tap” refer to the installation method of

the isolation valve kit only.

Standard Installation Hardware: For new construction or

scheduled shutdown, once kit is installed, the ow meter can

be installed or removed without system shutdown.

Hot Tap Installation Hardware: For applications which require the

access hole in the pipe to be drilled through the valve using a

wet tap drilling machine while the hydronic system is

pressurized and operating.

NOTE: Installation hardware materials vary greatly based on pipe material, pipe size and

standard vs. hot tap versions.

1.5 ADDITIONAL HARDWARE THAT MAY BE REQUIRED

1.5.1 Grounding Rings

Grounding rings may be required whenever meters are installed in non-metallic or lined pipes.

Grounding rings placed before and after the meter eliminate 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.

SECTION 2.0: UNPACKING

ONICON insertion magnetic ow meters are packed and shipped in individual cartons. An optional

installation hardware kit INSTL 1 or INSTL 2, if ordered, will be packaged with each meter. All other

installation hardware and peripheral devices, including Btu meters and display modules, will be packaged

and shipped separately.

Please open all packages with care to prevent damage to their contents. Carefully inspect each item for

signs of damage in transit. The ow meter stem should be straight and free of blemishes or abrasions. The

sensor head should have a smooth continuous surface that is free of abrasions.

All ONICON products are shipped insured unless the customer specically requests otherwise. Please

notify the shipping company and ONICON immediately if any items are damaged in transit. Save all

packing material for inspection by the shipper.

SECTION 3.0: INSTALLATION, REMOVAL AND ADJUSTMENT

WARNING

Insertion ow meters may be installed in pipes which are under high pressure. Accidents with

these systems can cause serious injury or death. Only persons experienced with high pressure

systems and related knowledge in the heating, cooling and uid metering elds should attempt

to install, adjust, or remove the ow meter. Please read all instructions before attempting to

insert or remove a ow meter.

ONICON will be happy to assist with technical recommendations and to provide guidance by

telephone or e-mail. On-site eld engineering, installation and service is also available at 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 typically 30”- 40” 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.

3.1.1 General Site Selection Guidelines

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 recommendations vary based on the nature of the upstream obstruction.

See the table below for guidelines in determining upstream straight run

recommendations based on the nature of the obstruction. Please note that depending

upon specic location details, more or less straight run may be required to produce a

satisfactory ow prole.
