SECTION 1.0: INTRODUCTION
We, at ONICON INCORPORATED, would like to thank you for purchasing our F-2500 Series Vortex
Flow Meter. As our valued customer, our commitment to you is to provide fast reliable service and
assistance, while continuing to offer you new products to meet your growing ow measurement needs.
1.1 PURPOSE OF THIS GUIDE
The purpose of this guide is to provide installation and commissioning procedures and basic
operating and servicing instructions for ONICON F-2500 Series Vortex Flow Meters.

WARNING
Only qualied service personnel should attempt to install or service this equipment. Serious injury
may result from the improper installation or use of this equipment.
1.2 PRINCIPAL OF OPERATION
ONICON F-2500 vortex ow meters utilize Karman’s vortex street principle to detect changes
in velocity in the medium owing around a bluff body contained within 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. A built-in temperature sensor and an optional pressure
sensor provide the compensation necessary for direct mass ow measurement of saturated or
superheated steam, liquids and a variety of industrial gases.
1.3 TYPICAL FLOW METER INSTALLATION
ONICON’s F-2500 In-line Vortex Flow Meters are suitable for volumetric and mass ow
measurement of air, gases, liquids or steam in a wide variety of applications.

1.6 ADDITIONAL HARDWARE THAT MAY BE REQUIRED
1.6.1 Flow Straightners
Flow straighteners may be required when an insufcient straight
run of pipe is available upstream of the proposed meter location.
ONICON provides ow straighteners as an optional accessory.
ONICON ow straighteners are wafer style ow conditioners
designed to be installed between two anges (provided by
installer) that are located a specic distance upstream of the ow
meter. The use of ow straighteners signicantly reduces the
upstream straight pipe length requirement for ONICON Vortex
Flow Meters.
The size of the ow straightener must match the meter size (as
opposed to the original pipe size).
The ow straightener is made from 304 stainless steel and is
provided with gaskets attached to each face.

SECTION 3.0: INSTALLATION INFORMATION
The F-2500 Vortex Flow Meter must be installed by experienced plumbers and pipe tters qualied to
work with pressurized liquid, steam and/or gas ow. The installation must conform to federal, state and
local building codes. ONICON will be happy to assist with technical recommendations and to provide
guidance via telephone or email. On site engineering, installation and service are also available, at an
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 1.7 Working Environment, as well as the following.
!
3.1.1 Orienting the Meter With Respect to the Direction of ow
The ow direction arrow on the neck of the sensor body as shown below must always be
oriented in the direction of ow in the pipe. This will correctly orient the bluff body so that
it faces incoming ow.
CAUTION
The installation guidelines presented below are minimum requirements for proper operation of this
ow meter.
!
CAUTION
Flow meters incorrectly oriented with respect to the ow direction will not function.
