1.2 PRINCIPAL OF OPERATION
ONICON F-2000 series vortex ow meters utilize Karman’s vortex street principal to detect changes
in velocity in the medium owing around the titanium shedder bar and through the meter body. A
volumetric ow rate is then derived by utilizing the known cross-sectional area of the meter body
and the average velocity of the medium. When provided with optional temperature and/or pressure
compensation the F-2000 series ow meters are capable of calculating the required density
corrections necessary to provide direct mass ow measurement of liquids, steam or gases.

1.4 ADDITIONAL REQUIRED MATERIALS
Installer is responsible for providing suitable anges and fasteners to connect the meter to the
process piping. In addition, most installations will also require one reducer, one expander, pipe
supports and a suf cient length of straight pipe (pipe diameter = meter size) to meet the installation
requirements outlined in this manual. Use of an optional ow recti er may be required in cases
where the available space is not suf cient to allow for proper upstream straight pipe run.
1.5 WORKING ENVIRONMENT
ONICON F-2000 series vortex ow meters are designed for use in industrial environments that are
free of corrosive liquids, fumes and excessive vibration. Do not expose the ow meter electronics
enclosure to direct sunlight. Install a sunshade if necessary. Do not expose the ow meter to intense
vibration. If necessary, provide additional support to the pipeline, at the meter location, to minimize
vibration. The rotating design of the electronics enclosure makes it easier to connect the power and
signal cables to the terminals in the rear of the enclosure. Rotate the enclosures as necessary before
installing the meter.
The ambient operating temperature range is 0° to 132° F.
1.6 SERIAL NUMBER
The serial number for your F-2000 series vortex ow meter is located on the metal identi cation
plate mounted on the side of the electronics enclosure. Please have this number available whenever
you contact ONICON for assistance.

SECTION 3.0: INSTALLATION INFORMATION
The F-2000 series vortex ow meter must be installed by a technician quali ed to work with pressurized
liquid, steam and/or gas ow and must conform to all federal, state and local building codes. ONICON will
be happy to assist with technical recommendations and to provide guidance via telephone or mail. On-site
engineering, installation and service are also available, at additional cost.
3.1 SITE SELECTION
Careful attention in locating the point in the piping system where the ow meter will be installed
will ensure accurate and reliable operation. When selecting an installation site, consider the criteria
contained in Section 1.5 WORKING ENVIRONMENT, as well as the following:
CAUTION
!
3.1.1 Flow Direction And Meter Position
The installation guidelines presented below are minimum requirements for the proper operation of
this ow meter.
The ow must always be in the direction of the arrow located on the meter body.
This will orient the bluff side of the vortex shedder bar so that it faces the incoming
ow (i.e. the upstream side).
For vertical pipe runs, ow must always be in the upward direction. Consult the
factory in the event that a downward owing pipe is the only available location.
F-2200 Series Vortex Flow Meter Installation and Operation Guide • Revised 12/08

The diagrams shown below illustrate the correct meter orientation for vertical and horizontal pipe.
3.1.2 Maximum Allowable Difference Between Inside Diameter Of Meter Body
And The Connecting Pipe
The table below provides the maximum allowable difference between the diameter of
the ow meter body and the connecting pipe.

3.1.3 Straight, Unimpeded Inlet And Outlet Runs
D = Meter Size (Nominal diameter in inches)
With a ow straightener, the inlet pipe length may be reduced by 50%. For example, with a
control valve upstream, the inlet length is 25D instead of 50D. The minimum inlet pipe length
including the ow straightener must always be at least 12D.
3.1.4 Minimizing Pipe Vibration
Pipe vibration caused, for example, by the action of pumps, valves, etc. will distort ow
measurements, particularly at low ow velocities. To minimize the effects of vibration,
support the pipeline on both sides of the meter in a direction perpendicular to both the
pipeline and the shedder bar axis.
F-2200 Series Vortex Flow Meter Installation and Operation Guide • Revised 12/08
13
3.1.5 Locating The Meter In A Pipline That Runs Parallel To A Wall
Wherever possible, the distance between the pipe centerline and the wall should be greater
than 20”. This will allow for access to the electronics enclosure compartment where wire
terminations are made. If adequate space is not available, rst connect all the cables to the
terminals in the connection compartment (power supply and outputs) and then run the wires
to an intermediate junction box (also see Section 3.2) before installing the meter.
3.1.6 State Of Medium
In all cases the meter requires a single-phase ow for proper operation. Liquid droplets in
the gas or vapor, solid particles in the gas or liquid and gas bubbles in the liquid are not
permitted.
3.1.6.1 Liquid Applications
When operating with liquids, the meter requires a minimum downstream pressure
to prevent cavitation. The formula used to determine the minimum downstream
pressure is as follows:
Pds(bar_g) > =(2.9*DP) + (1.3*Ps)-1.013
Where DP=pressure drop of the meter, in Bar, as determined by the ONICON sizing
program and Ps=saturation pressure, in Bar, at the operating temperature.
For any uid, a lter or strainer may be used to remove the solid particles. This is
especially important for meter sizes below 1” where a lter or a strainer is required.
3.1.6.2 Steam Or Compressed Gas Applications
In case of steam or compressed gas, a moisture separator should be used 50D
upstream of the meter if the dryness fraction is less than 95%.
IMPORTANT NOTE
i
Steam quality will affect the accuracy of the measurement. It is strongly recommended that a moisture
separator be installed upstream of the inlet straight pipe run for anything less than 95% dry steam.

3.2 MECHANICAL INSTALLATION
3.2.1 Orient The Display For Convenient Viewing
Both the electronics enclosure and the display itself can be rotated to four different
orientations to change the viewing angle for the display. If necessary, this should be done
before the meter is installed.
3.2.1.1 Rotating the electronics enclosure
The electronics enclosure is attached to the meter body with (4) 5mm Allen head
screws. To rotate the enclosure, you must rst remove the screws and then carefully
rotate the enclosure as needed. The interconnecting stem assembly is a conduit for
wires that connect the sensors to the circuitry contained in the enclosure. Care must
be taken to prevent these wires from being damaged when rotating the enclosure.
!
CAUTION
Make certain the sensor wires are not damaged when re-attaching the enclosure.

4.1 START UP
When the power is applied to the F-2000 series vortex meter, alphanumeric characters will appear
on the display. Initially, the meter will operate in a “TEST” mode where self diagnostic checks are
performed on the pre-ampli er and sensor circuits. Following this, con guration data is loaded
from the non-volatile memory and the program advances to the measurement mode.
IMPORTANT NOTE
i
!
4.2 MEASUREMENT MODE
In the measurement mode, the display
indicates real-time ow, temperature and/
or pressure data in the appropriate units.
The top line of the display indicates the
current measured value. The second line
of the display indicates the programmed
units of measurement.
There are two options for displaying data in
the measurement mode. The display may
be set to automatically scroll through each
menu page or it may be set to manually step
through the menu pages using the up arrow
key to advance each page. Displays operating
in the cyclic mode will advance through
each page every 6 seconds.
The meter should be installed and powered for at least 15 minutes before media is allowed to ow
through the meter.
Flow velocity through the meter should be increased gradually until full ow is achieved.
CAUTION
IMPORTANT NOTE
When measuring steam ow, condensate may form on the cool surfaces of the meter and piping
system when the system is started up for the rst time (causing faulty measurement).

4.5 TROUBLESHOOTING HINTS
REPORTED
PROBLEM
A non-zero fl ow indi-
cated when no actual
fl ow is in the pipe.
“CHECK INST.” error
is displayed when no
fl ow is in the pipe.
POSSIBLE
SOLUTIONS
• Mains interference due to improper Earth ground connection. The protective
Earth PE terminal should be properly grounded (see page 17).
• Excessive mechanical vibration in the pipe. If so, support the pipeline near the
meter perpendicular to both the axis of the pipe and the axis of the shedder
bar.
• This problem may also be solved by reducing the factory set gain. (Contact
ONICON for assistance.)
NOTE: By reducing the gain, the minimum measurable fl ow rate will go up
by the factor which is approximately equal to the square root of the gains
(odd gains new gain). If the minimum fl ow with reduced gain is above the
minimum fl ow which is required to be measured, then reducing the gain is
not the permanent solution. Then the installaion should be corrected and
also the vibrations should be eliminated.
The display should normally indicate 0.0 fl ow rate, LOW FLOW or LOW SIGNAL
when there is no fl ow in the pipe. The additional CHECK INSTALL error (fl ow
rate = 0.0 or some steady or fl uctuating value) is an indication of:
• Improper/inadequate earthing
• Excessive pipe vibration
Flow rate inidcated is
0.0 even with fl ow in
the pipe.
The fl ow indicated
responds to changes
in the fl ow but the
indicated value does
not correspond to the
actual fl ow rate. Also
“CHECK INST.” Error
may appear intermittently.
• The vortex sensor cable is disconnected or is not properly connected.
• Flow sensor is faulty. Contact ONICON for assistance.
• The meter is not properly centered on the pipeline. The axis of the meter bore
should be aligned with that of the pipe.
• Gaskets at the meter are protruding into the pipe bore. The gaskets must not
project into the effective cross-section of the pipe.
• Irregularities on the surface of the pipe bore. The pipe bore should be free from
irregularities at the welded joints, dirt, deposits and excessive surface roughness.
• The Vortex signal is distorted due to a bi-phase medium. Bi-phase media are
not permitted. Use a moisture separator for wet steam applications to remove
the moisture droplets from the steam. Use suitable fi lters in gas applications to
remove solid particles from the fl owing gas. • Incorrect angular position of the
meter. Refer to Section 3.1.1 for the allowable mounting positions.
• Insuffi cient upstream/downstream pipe lengths. Check that the upstream/
downstream pipe lengths are of the correct minimum length as given in
Section 3.1.3.
• Error in meter factor K-Factor programming. Contact ONICON for assistance.
• Check that the fl ow direction and the direction arrow on the meter body agree.
