SECTION 1.0: INTRODUCTION

1.1 ONICON F-2600 & F-2700 SERIES VORTEX MASS FLOW METERS

The ONICON F-2600 Series In-line and F-2700 Series Insertion Vortex Flow Meters provide a
reliable solution for process ow measurement. From a single entry point in the pipeline, F-2600
meters offer precise measurements of mass or volumetric ow rates.

Multi-Parameter Mass Flow Meters

Mass ow meters utilize three primary sensing elements: a vortex shedding velocity sensor, an
RTD temperature sensor, and a solid state pressure sensor to measure the mass ow rate of gases,
liquids, and steam.
Meters are available as loop powered devices or with up to three 4-20 mA analog output signals
for monitoring your choice of the ve process variables (mass ow, volumetric ow, temperature,
pressure and uid density). The Energy Monitoring option permits
real-time calculation of energy consumption for a facility or process.

Volumetric Flow Meters

The primary sensing element of a volumetric ow meter is a vortex shedding velocity sensor.
Meters are loop powered. The analog 4-20 mA output signal offers your choice of volumetric
or mass ow rate. Mass ow rate is based on a constant value for uid density stored in the
instrument’s memory.

Both the mass and volumetric ow meters can be ordered with a local keypad/display
which provides instantaneous ow rate, total, and process parameters in engineering units. A
pulse output signal for remote totalization and BACnet MS/TP, MODBUS RTU RS485 or HART
communications are also available. Digital electronics allow for easy reconguration for most gases,
liquids and steam. ONICON meters’ simple installation combines with an easy-to-use interface that
provides quick set up, long term reliability and accurate mass ow measurement over a wide range
of ows, pressures and temperatures.

1.2 HOW THE ONICON VORTEX MASS FLOW METER OPERATES

Figure 1. In-Line Multi-Parameter Vortex Mass Flow Meter

ONICON F-2600 Series & F-2700 Series Vortex Mass Flow Meters use a unique sensor
head to monitor mass ow rate by directly measuring three variables. uid velocity,
temperature and pressure. The built-in ow computer calculates the mass ow rate
and volumetric ow rate based on these three direct measurements. The sensing head
is built into the vortex meter’s ow body. To measure uid velocity, the ow meter
incorporates a bluff body (shedder bar) in the ow stream and measures the frequency of
vortices created by the shedder bar. Temperature is measured using a platinum resistance
temperature detector (PRTD). Pressure measurement is achieved using a solid-state
pressure transducer. All three elements are combined into an integrated sensor head
assembly located downstream of the shedder bar within the ow body.

1.2.1 Velocity Measurement

ONICON’s vortex velocity sensor is a patented mechanical design that minimizes the
effects of pipeline vibration and pump noise, both of which are common error sources
in ow measurement with vortex ow meters. The velocity measurement is based on the
well-known Von Karman vortex shedding phenomenon. Vortices are shed from a shedder
bar, and the vortex velocity sensor located downstream of the shedder bar senses the
passage of these vortices. This method of velocity measurement has many advantages
including inherent linearity, high turndown, reliability and simplicity.

F-2600 & F-2700 Vortex Flow Meter Manual 02/15 - 0808-7 / 19204 Page 13

1.2.2 Vortex Shedding Frequency

Von Karman vortices form downstream of a shedder bar into two distinct wakes.
The vortices of one wake rotate clockwise while those of the other wake rotate
counterclockwise. Vortices generate one at a time, alternating from the left side to the right
side of the shedder bar. Vortices interact with their surrounding space by over-powering
every other nearby swirl on the verge of development. Close to the shedder bar, the
distance (or wave length) between vortices is always constant and measurable. Therefore,
the volume encompassed by each vortex remains constant, as shown below. By sensing
the number of vortices passing by the velocity sensor, the F-2600 & F-2700 Flow Meter
computes the total uid volume.

Figure 2. Measurement Principle of Vortex Flow Meters

1.2.3 Vortex Frequency Sensing

The velocity sensor incorporates a piezoelectric element that senses the vortex frequency.
This element detects the alternating lift forces produced by the Von Karman vortices
owing downstream of the vortex shedder bar. The alternating electric charge generated by
the piezoelectric elements is processed by the transmitter’s electronic circuit to obtain the
vortex shedding frequency. The piezoelectric element is highly sensitive and operates over
a wide range of ows, pressures and temperatures.

1.2.4 Flow Velocity Range

To ensure trouble-free operation, vortex ow meters must be correctly sized so that the
ow velocity range through the meter lies within the measurable velocity range (with
acceptable pressure drop) and the linear range.

The measurable range is dened by the minimum and maximum velocity using the
following table.

The pressure drop for F-2700 insertion meters is negligible. The pressure drop for F-2600
in-line meters is dened as:

∆P = .00024 ρ V2 English units (∆P in psi, ρ in lb/ft3, V in ft/sec)
∆P = .000011 ρ V2 Metric units (∆P in bar, ρ in kg/m3, V in m/sec)

The linear range is dened by the Reynolds number. The Reynolds number is the ratio of
the inertial forces to the viscous forces in a owing uid and is dened as:

Where
Re = Reynolds Number
ρ = mass density of the uid being measured
V = velocity of the uid being measured
D = internal diameter of the ow channel
 = viscosity of the uid being measured

Re =

The Strouhal number is the other dimensionless number that quanties the vortex
phenomenon. The Strouhal number is dened as:

Where
St = Strouhal Number
f = frequency of vortex shedding
d = shedder bar width
V = uid velocity

As shown in Figure 3, F-2600 & F-2700 meters exhibit a constant Strouhal number across
a large range of Reynolds numbers, indicating a consistent linear output over a wide
range of ows and uid types. Below this linear range, the intelligent electronics in the
meter automatically corrects for the variation in the Strouhal number with the Reynolds
number. The meter’s smart electronics corrects for this non-linearity via its simultaneous
measurements of the process uid temperature and pressure. This data is then used to
calculate the Reynolds number in real time. The meter automatically corrects down to a
Reynolds number of 5,000.

1.2.5 Temperature Measurement

This ow meter uses a 1000 ohm platinum resistance temperature detector (PRTD) to
measure uid temperature.

1.2.6 Pressure Measurement

Both versions of the meter incorporate a solid-state pressure transducer isolated by a 316
SS diaphragm. The transducer itself is micro-machined silicon, fabricated using integrated
circuit processing technology. A nine-point pressure/temperature calibration is performed
on every sensor. Digital compensation allows these transducers to operate within a 0.3%
of full scale accuracy band within the entire ambient temperature range of -40°F to 140°F
(-40°C to 60°C). Thermal isolation of the pressure transducer ensures the same accuracy
across the allowable process uid temperature range of -330°F to 750°F (-200°C to 400°C).

1.3 Flow Meter Congurations

Our vortex mass ow meters are available in two model congurations:
In-line F-2600 Series Flow Meters (replaces a section of the pipeline)
Insertion F-2700 Series Flow Meters (requires a tap into an existing pipeline)

Both the in-line and insertion congurations are similar in that they both use identical electronics
and have similar sensor heads. Besides installation differences, the main difference between an
in-line ow meter and an insertion ow meter is their method of measurement.

For an in-line vortex ow meter, the shedder bar is located across the entire diameter of the
ow body. Thus, the entire pipeline ow is included in the vortex formation and measurement.
The sensing head, which directly measures velocity, temperature and pressure, is located just
downstream of the shedder bar.

Insertion vortex ow meters have a shedder bar located across the diameter of a short tube. The
velocity, temperature and pressure sensor is located within this tube just downstream of a built­in shedder bar. This entire assembly is called the insertion sensing head. It ts through any entry
port with a 1.875 inch minimum internal diameter.

The sensing head of an insertion vortex ow meter directly monitors the velocity at a point in
the cross-sectional area of a pipe, duct, or stack (referred to as “channels”). The velocity at a
point in the pipe varies as a function of the Reynolds number. The insertion vortex ow meter
computes the Reynolds number and then computes the total ow rate in the channel. The output
signal of insertion meters is the total ow rate in the channel. The accuracy of the total ow rate
computation depends on adherence to the piping installation requirements given in Section 2. If
adherence to those guidelines cannot be met, contact ONICON for specic installation advice.

1.3.1 Multivariable Options

The both versions of the meter are capable of providing the following ow measurement
options:
Volumetric ow; Mass ow with temperature compensation; Mass ow with temperature
and pressure compensation; Steam energy ow with temperature compensation;
Steam energy ow with temperature and pressure compensation, Mass or Energy ow
with temperature and external pressure compensation and Net Energy using a second
temperature sensor.

1.3.2 Line Size / Process Connections / Materials

The in-line model is built for line sizes ½" through 4" wafer or ½" through 8" anged
design using ANSI 150, 300, 600, PN16, 40, or 64 class anges.

The insertion model can be used in line sizes 2" and greater and is built with a packing
gland design using 2" NPT, or 2" anged connections (ANSI 150, 300, 600, PN16, 40, or 64
class anges). The packing gland design can be ordered with a permanent or removable
retractor.

The standard in-line model is built with 316L stainless steel, A105 carbon steel and
Hastelloy C-276 versions are available via special order. The insertion model is built with
316L stainless steel.

1.3.3 Flow Meter Electronics

The ow meter electronics are available mounted directly to the ow body, or mounted
remotely. The electronics housing may be used indoors or outdoors, including wet
environments. Available input power options are: DC loop powered (2-wire), DC powered,
or AC powered. Three analog output signals are available for your choice of three of the
ve process variables: mass ow rate, volumetric ow rate, temperature, pressure or uid
density. A pulse output signal for remote totalization and BACnet, MODBUS or HART
communications is also available.

Each meter includes a local 2 x 16 character LCD display housed within the enclosure.
Local operation and reconguration is accomplished using six pushbuttons operated via
nger touch. For hazardous locations, the six buttons can be operated with the electronics
enclosure sealed using a hand-held magnet, thereby not compromising the integrity of the
hazardous location certication.

The electronics include nonvolatile memory that stores all conguration information. The
nonvolatile memory allows the ow meter to function immediately upon power up or after
an interruption in power. All owmeters are calibrated and congured for the customer’s
ow application.

SECTION 2.0 INSTALLATION

!

2.1 INSTALLATION OVERVIEW

ONICON F-2600 & F-2700 Vortex Flow Meter installations are simple and straightforward.
Both the in-line and the insertion type ow meter installations are covered in this chapter.
After reviewing the installation requirements given below, see page 21 for in-line installation
instructions. See page 24 for insertion style installation instructions. Wiring instructions begin on
page 38.

2.1.1 Flow Meter Installation Requirements

WARNING

Consult the ow meter nameplate for specic ow meter approvals before any hazardous location
installation.

Before installing the ow meter, verify the installation site allows for these considerations:

1. Line pressure and temperature will not exceed the ow meter rating.

2. The location meets the required minimum number of pipe diameters upstream and
downstream of the sensor head as illustrated in Figure 4.

3. Safe and convenient access with adequate overhead clearance for maintenance
purposes.

4. Verify that the cable entry into the instrument meets the specic standard required for
hazardous area installations.

5. For remote installations, verify the supplied cable length is sufcient to connect the
ow meter sensor to the remote electronics.

Also, before installation, check your ow system for anomalies such as:

• leaks

• valves or restrictions in the ow path that could create disturbances in the ow prole
that might cause unexpected ow rate indications

2.1.2 Unobstructed Flow Requirements

Select an installation site that will minimize possible distortion in the ow prole. Valves,
elbows, control valves and other piping components may cause ow disturbances. Check
your specic piping condition against the examples shown below. In order to achieve
accurate and repeatable performance, install the ow meter using the recommended
number of straight run pipe diameters upstream and downstream of the sensor.

Note: For liquid applications in vertical pipes, avoid installing with ow in the downward
direction because the pipe may not be full at all points. Choose to install the meter with
ow in the upward direction, if possible.

2.2 F-2600 SERIES IN-LINE FLOW METER INSTALLATION

Install the in-line ow meter between two conventional pipe anges as shown in Figures 6 and

7. Table 1 provides the recommended minimum stud bolt lengths for wafer-style meter body size
and different ange ratings.

The meter's inside diameter is equal to the same size nominal pipe ID in schedule 80. For
example, a 2” meter has an ID of 1.939” (2” schedule 80). Do not install the meter in a pipe with
an inside diameter smaller than the inside diameter of the meter. For schedule 160 and higher
pipe, a special meter is required. Consult the factory before purchasing the meter.

In-line meters require customer-supplied gaskets. When selecting gasket material, make sure that
it is compatible with the process uid and pressure ratings of the specic installation. Verify that
the inside diameter of the gasket is larger than the inside diameter of the ow meter and adjacent
piping. If the gasket material extends into the ow stream, it will disturb the ow and cause
inaccurate measurements.

2.2.1 Wafer-Style Flow Meter Installation

!

Install the wafer-style meter between two conventional pipe anges of the same nominal
size as the ow meter. If the process uid is a liquid, make sure the meter is located where
the pipe is always full. This may require locating the meter at a low point in the piping
system. Note: Vortex ow meters are not suitable for two-phase ows (i.e., liquid and gas
mixtures). For horizontal pipelines having a process temperature above 300° F, mount the
meter at a 45 or 90 angle to avoid overheating the electronics enclosure. To adjust the
viewing angle of the enclosure or display/keypad, see page 34 and 35.

Figure 6. Wafer-Style Flow Meter Installation

CAUTION

When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at
full gas ow before installing the ow meter.

When installing the meter make sure the section marked with a ow arrow is positioned
upstream of the outlet, with the arrow head pointing in the direction of ow. (The mark
is on the wafer adjacent to the enclosure mounting neck.) This ensures that the sensor
head is positioned downstream of the vortex shedder bar and is correctly aligned to the
ow. Installing the meter opposite this direction will result in completely inaccurate ow
measurement. To install the meter:

1. Conrm that the installation site meets the required minimum upstream and
downstream pipe diameters. Turn off the ow of process gas, liquid or steam. Verify
that the line is not pressurized.

2. Insert the studs for the bottom side of the meter body between the pipe anges. Place
the wafer-style meter body between the anges with the end stamped with a ow arrow
on the upstream side, with the arrow head pointing in the direction of ow. Center the
meter body inside the diameter with respect to the inside diameter of the adjoining
piping.

3. Position the gasket material between the mating surfaces. Make sure both gaskets are
smooth and even with no gasket material extending into the ow prole. Obstructions
in the pipeline will disturb the ow and cause inaccurate measurements.

4. Place the remaining studs between the pipe anges. Tighten the nuts in the sequence
shown in Figure 5. Check for leaks after tightening the ange bolts.

2.2.2 Flange-Style Flow Meter Installation

!

Install the ange-style meter between two conventional pipe anges of the same nominal
size as the ow meter. If the process uid is a liquid, make sure the meter is located where
the pipe is always full. This may require locating the meter at a low point in the piping
system. Note: Vortex ow meters are not suitable for two-phase ows (i.e., liquid and gas
mixtures). For horizontal pipelines having a process temperature above 300° F, mount the
meter at a 45° or 90° angle to avoid overheating the electronics enclosure. To adjust the
viewing angle of the enclosure or display/keypad, see page 34 and 35.

Figure 7. Flange-Style Flow Meter Installation

CAUTION

When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at
full gas ow before installing the ow meter.

When installing the meter make sure the ange marked with a ow arrow is positioned
upstream of the outlet ange, with the arrow head pointing in the direction of ow. (The
mark is on the ange adjacent to the enclosure mounting neck.) This ensures that the
sensor head is positioned downstream of the vortex shedder bar and is correctly aligned to
the ow. Installing the meter opposite this direction will result in completely inaccurate
ow measurement. To install the meter:

1. Conrm that the installation site meets the required minimum upstream and

downstream pipe diameters. Turn off the ow of process gas, liquid or steam. Verify
that the line is not pressurized.

2. Seat the meter level and square on the mating connections with the ange stamped

with a ow arrow on the upstream side, with the arrow head pointing in the direction
of ow. Position a gasket in place for each side. Make sure both gaskets are smooth
and even with no gasket material extending into the ow prole. Obstructions in the
pipeline will disturb the ow and cause inaccurate measurements.

3. Install bolts in both process connections. Tighten the nuts in the sequence shown in

Figure 5. Check for leaks after tightening the ange bolts.

2.3 F-2700 SERIES INSERTION FLOW METER INSTALLATION

Prepare the pipeline for installation using either a standard or hot tap method described on the
following pages. Refer to a standard code for all pipe tapping operations. The following tapping
instructions are general in nature and intended for guideline purposes only. Before installing the
meter, review the mounting position and isolation value requirements given below.

Mounting Position

Allow clearance between the electronics enclosure top and any other obstruction when the meter
is fully retracted.

Isolation Valve Selection

Always install an isolation valve with insertion style meters. If you supply the isolation valve, it
must meet the following requirements:

1. A minimum valve bore diameter of 1.875" is required, and the valve’s body size should be 2".
Normally, gate valves are used.

2. Verify that the valve’s body and ange
rating are within the ow meter’s maximum operating pressure and temperature.

3. Choose an isolation valve with at least two inches existing between the ange face and the
gate portion of the valve. This ensures that the ow meter’s sensor head will not interfere with
the operation of the isolation valve.

2.3.1 Standard Installation Guidelines

!

!

CAUTION

When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at
full gas ow before installing the ow meter.

Refer to a standard code for all pipe tapping operations. The following tapping
instructions are general in nature and intended as a guideline only.

1. Conrm that the installation site meets the minimum upstream and downstream pipe
diameter requirements. See Figure 4.

2. Turn off the ow of process gas, liquid or steam. Verify that the line is not pressurized.

3. Use a cutting torch or sharp cutting tool to tap into the pipe. The pipe opening must be
at least 1.875" in diameter. (Do not attempt to insert the sensor probe through a smaller
hole.)

4. Remove all burrs from the hole. Rough edges may cause ow prole distortions that
could affect ow meter accuracy. Also, obstructions could damage the sensor assembly
when inserting into the pipe.

WARNING

All ow meter connections, isolation valves and ttings for cold tapping must have the same or
higher pressure rating as the main pipeline.

5. After cutting, measure the thickness of the cut-out and record this number for
calculating the insertion depth.

6. Weld the ow meter pipe connection onto the pipe.
Make sure this connection is within ± 5°
perpendicular to the pipe centerline.

7. Install the isolation valve.

8. When welding is complete and all ttings are installed, close the isolation valve or cap
the line. Run a static pressure check on the welds. If pressure loss or leaks are detected,

repair the joint and re-test.

9. Connect the meter to the pipe process connection.

10. Calculate the sensor probe insertion depth and insert the sensor probe into the pipe as
described on the following pages.

responsible for providing proof of such a permit.

Refer to a standard code for all pipe tapping operations. The following tapping instructions
are general in nature and intended as a guideline only.

1. Conrm that the installation site meets the minimum upstream and downstream pipe
diameter requirements.

2. Weld a 2" mounting adapter on the pipe. Make sure the mounting adapter is within ± 5°
perpendicular to the pipe centerline (see previous page). The pipe opening must be at least

1.875" in diameter.

3. Connect a 2" process connection on the mounting adapter.

4. Connect an isolation valve on the process connection. The valve’s full open bore must be
at least 1.875" in diameter.

5. Run a static pressure check on the welds. If pressure loss or leaks are detected, repair the
joint and re-test.

6. Connect the hot tapping equipment to the isolation valve, open the isolation valve and
drill at least a 1.875" diameter hole.

7. Retract the drill, close the isolation valve, and remove the hot tapping equipment.

8. Connect the ow meter to the isolation valve and open the isolation valve.

9. Calculate the sensor probe insertion depth and insert the sensor probe into the pipe as
described on the following pages.

WARNING

All ow meter connections, isolation valves, and ttings for hot tapping must have the same or
higher pressure rating as the main pipeline.

2.4 FLOW METER INSERTION

!

The sensor head must be properly positioned in the pipe. For this reason, it is important that
insertion length calculations are carefully followed. A sensor probe inserted at the wrong depth
in the pipe will result in inaccurate readings.

Insertion ow meters are applicable to pipes 2" and larger. For pipe sizes 10" and smaller, the
centerline of the meter’s sensing head is located at the pipe’s centerline. For pipe sizes larger than
10", the centerline of the sensing head is located in the pipe’s cross section 5" from the inner wall
of the pipe; i.e., its “wetted” depth from the wall to the centerline of the sensing head is 5".

Insertion ow meters are available in two probe lengths:

Standard Probe conguration is used with most ow meter process connections. The length, S, of
the stem is 29.47".

12-Inch Extended Probe conguration is used with exceptionally lengthy ow meter process
connections. The length, S, of the stem is 41.47".

Use the Correct Insertion Formula

Depending on your ow meter’s process connection, use the applicable insertion length formula
and installation procedure as follows:

• Flow meters with a packing gland type connection (NPT or anged) congured with an
insertion tool, follow the instructions beginning on page 29.

• Flow meters with a packing gland type connection (NPT or anged) without an insertion tool,
follow the instructions beginning on page 32.

WARNING

An insertion tool must be used for any installation where a ow meter is inserted under pressure
greater than 50 psig.

2.4.1 Installing Flow Meters with a Packing Gland Connection*

Use the formula below to determine the insertion depth for ow meters (NPT and anged)
equipped with an insertion tool. To install, see the next page for instructions for meters
with a permanent insertion tool. For meters with a removable insertion tool, see page 33.

Insertion Length Formula

I = F + R + t – 1.35

Where:

I

I = Insertion length.

F = Distance from the raised face of the ange or top of
the process connection for NPT style meters to the
top outside of the process pipe.

F

t

R

R = Pipe inside diameter ÷ 2 for pipes ten" & smaller.

R = Five" for pipe diameters larger than ten".

t = Thickness of the pipe wall. (Measure the disk
cutout from the tapping procedure or check a piping
handbook for thickness.)

Figure 10. Insertion Calculation (Meters with Insertion Tool)

Example 1: Flange Style Meters:

To install an insertion style ow meter into a 14" schedule 40 pipe, the following
measurements are taken:

F = 12"
R = 5"
t = 0.438"

The example insertion length is 16.09".

Example 2: NPT Style Meters:

The length of thread engagement on the NPT style meters is also subtracted in the equation.
The length of the threaded portion of the NPT meter is 1.18". Measure the thread portion
still showing after the installation and subtract that amount from 1.18". This gives you the
thread engagement length. If this cannot be measured use .55" for this amount.

F = 12"
R = 5"
t = 0.438"

The example insertion length is 15.54".

*All dimensions are in inches.

2.4.2 Insertion Procedure for Flow Meters with Permanent Insertion Tool

!

! i !

Figure 11. Flow Meter with Permanent Insertion Tool

1. Calculate the required sensor probe insertion length (see previous page). Measure
from the depth marker arrow down the stanchion and scribe a mark at the calculated
insertion depth.

2. Fully retract the ow meter until the sensor head is touching the bottom of the stem
housing. Attach the meter assembly to the 2" full-port isolation valve, if used. Use
Teon tape or pipe sealant to improve seal and prevent seizing on NPT style.

3. Loosen the two packing gland nuts on the stem housing of the meter. Loosen the
stem lock bolt adjacent to the sensor alignment pointer. Align the sensor head using
the sensor alignment pointer. Adjust the alignment pointer parallel to the pipe and
pointing downstream. Tighten the stem lock bolt to secure the sensor position.

4. Slowly open the isolation valve to the full open position. If necessary, slightly
tighten the two packing gland nuts to reduce the leakage around the stem.

5. Turn the insertion tool handle clockwise to insert the sensor head into the pipe.
Continue until the top of the upper retractor bracket aligns with the insertion length
position scribed on the stanchion. Do not force the stem into the pipe.

6. Tighten the packing gland nuts to stop leakage around the stem. Do not torque over
20 ft-lb.

CAUTION

The sensor alignment pointer must point downstream, in the direction of ow.

IMPORTANT NOTE

If line pressure is above 500 psig, it could require up to 25 ft lb of torque to insert the ow meter.
Do not confuse this with possible interference in the pipe.

Figure 12. Flow Meter with Removable Insertion Tool

1. Calculate the required sensor probe insertion length. Measure from the depth marker
arrow down the stanchion and scribe a mark at the calculated insertion depth.

2. Fully retract the ow meter until the sensor head is touching the bottom of the stem
housing. Attach the meter assembly to the 2" full-port isolation valve, if used. Use
Teon tape or pipe sealant to improve seal and prevent seizing on NPT style.

3. Remove the two top stem clamp nuts and loosen two stem clamp bolts. Slide the stem
clamp away to expose the packing gland nuts.

4. Loosen the two packing gland nuts. Loosen the stem lock bolt adjacent to the sensor
alignment pointer. Align the sensor head using the sensor alignment pointer. Adjust
the alignment pointer parallel to the pipe and pointing downstream. Tighten the stem
lock bolt to secure the sensor position.

5. Slowly open the isolation valve to the full open position. If necessary, slightly tighten
the two packing gland nuts to reduce the leakage around the stem.

6. Turn the insertion tool handle clockwise to insert the stem into the pipe. Continue
until the top of the upper retractor bracket lines up with the insertion length mark
scribed on the stanchion. Do not force the stem into the pipe.

CAUTION

The sensor alignment pointer must point downstream in the direction of ow.

IMPORTANT NOTE

If line pressure is above 500 psig, it could require up to 25 ft lb of torque to insert the ow meter.
Do not confuse this with possible interference in the pipe.

7. Tighten the packing gland nuts to stop leakage around the stem. Do not torque over 20 ft-lbs.

8. Slide the stem clamp back into position. Torque stem clamp bolts to 15 ft-lbs. Replace the stem
clamp nuts and torque to 10-15 ft-lbs.

9. To separate the insertion tool from the ow meter, remove four socket head cap bolts securing
the upper and lower retractor brackets. Remove the insertion tool.

2.4.4 Installation of Meters with Packing Gland Connection (No Insertion Tool)*

Use the following formula to determine insertion depth for meters with a packing gland
connection (NPT and anged) without an insertion tool.

Insertion Length Formula

I = S - F - R - t

Where:

I = Insertion length.

S = Stem length - the distance from the center of the sensor
head to the base of the enclosure adapter (S = 29.47"
for standard probes; S = 41.47" for 12" extended probes).

F = Distance from the raised face of the ange or top of NPT
stem housing to the outside of the pipe wall.

R = Pipe inside diameter ÷ 2 for pipes 10" & smaller.

R = 5" for pipe diameters larger than 10".

t = Thickness of the pipe wall. (Measure the disk cutout
from the tapping procedure or check a piping
handbook for thickness.)

Figure 13. Insertion Calculation (Meters without Insertion Tool)

Example:

To install an insertion style ow meter with a standard probe (S = 29.47) into a 14"
schedule 40 pipe, the following measurements are taken:

F = 3"
R = 5"
t = 0.438"
The example insertion length is 21.03".

*All dimensions are in inches.

2.4.5 Insertion Procedure for Flow Meters with No Insertion Tool (Packing Gland Connection)

!

!

1. Calculate the required sensor probe insertion length.

2. Fully retract the stem until the sensor head is touching the bottom of the stem housing.
Remove the two top stem clamp nuts and loosen two stem clamp bolts. Slide the stem
clamp away to expose the packing gland nuts. Loosen the two packing gland nuts.

3. Align the sensor head using the sensor alignment pointer. Adjust the alignment pointer
parallel to the pipe and pointing downstream.

4. Insert the sensor head into the pipe until insertion length, I, is achieved. Do not force
the stem into the pipe.

5. Tighten the packing gland nuts to stop leakage around the stem. Do not torque over 20
ft-lbs.

6. Slide the stem clamp back into position. Torque stem clamp bolts to 15 ft-lbs. Replace
the stem clamp nuts and torque to 10-15 ft-lbs.

WARNING

The line pressure must be less than 50 psig for installation.

CAUTION

The sensor alignment pointer must point downstream, in the direction of ow.

WARNING

To avoid potential electric shock, follow National Electric Code safety practices or your local code
when wiring this unit to a power source and to peripheral devices. Failure to do so could result in
injury or death. All wiring procedures must be performed with the power off.

The NEMA 4X enclosure contains an integral wiring compartment with one dual strip terminal
block (located in the smaller end of the enclosure). Two ¾" female NPT conduit entries are
available for separate power and signal wiring. For all hazardous area installations, make sure
to use an agency-approved tting at each conduit entry. If conduit seals are used, they must be
installed within 18" (457 mm) of the enclosure.

2.6.2 4-20 mA OUTPUT CONNECTIONS

The loop powered meter has a single 4-20 mA loop. The 4-20 mA loop current is
controlled by the meter electronics. The electronics must be wired in series with the sense
resistor or current meter. The current control electronics requires at least 12 volts at the
input terminals to operate correctly.

The maximum loop resistance (load) for the current loop output is dependent upon the
supply voltage and is given in Figure 18. The 4-20 mA loop is optically isolated from the
ow meter electronics.

2.6.3 Pulse Output Connections

The pulse output is used for remote totalization. When the preset volume or mass (dened
in the totalizer settings, see page 62) has passed the meter, the output provides a 50
millisecond square pulse.

The pulse output requires a separate 5 to 36 VDC power supply. The pulse output optical
relay is a normally-open single-pole relay. The relay has a nominal 200 volt/160 ohm
rating. This means that it has a nominal on-resistance of 160 ohms, and the largest voltage
that it can withstand across the output terminals is 200 volts. However, there are current
and power specications that must be observed. The relay can conduct a current up
to 40 mA and can dissipate up to 320 mW. The relay output is isolated from the meter
electronics and power supply.

One alarm output (Alarm 1) is included on the standard meter. Two or more alarms (Alarm
2 and Alarm 3) are included on the optional communication board. The alarm output
optical relays are normally open single-pole relays. The relays have a nominal 200 V /
160 ohm rating. This means that each relay has a nominal on-resistance of 160 ohms and
the largest voltage that it can withstand across the output terminals is 200 V. However,
there are current and power specications that must be observed. The relay can conduct
a current up to 40 mA and can dissipate up to 320 mW. The relay output is isolated from
the meter electronics and power supply. When the alarm relay is closed, the current draw
will be constant. Make sure to size Rload appropriately.

There are three connection options for the alarm output. The rst has separate power
supply (Figure 37). The second uses the ow meter power supply (Figure 38) (DC powered
units only) and the third uses the meter provided power supply (Figure 39)(AC powered

The meter is shipped with temporary strain relief glands at each end of the cable.
Disconnect the cable from the meter’s terminal block inside the junction box, not at the
remote electronics enclosure. Remove both glands and install appropriate conduit entry
glands and conduit. When installation is complete, re-connect each labeled wire to the
corresponding terminal position on the junction box terminal block. Make sure to connect
each wire pair’s shield. Note: Incorrect connection will cause the meter to malfunction.

Use the Totalizer Menu to congure and monitor the totalizer. The totalizer output is a 50
millisecond (.05 second) positive pulse (relay closed for 50 milliseconds). The totalizer
cannot operate faster than one pulse every 100 millisecond (.1 second). A good rule to
follow is to set the unit per pulse value equal to the maximum ow in the same units per
second. This will limit the pulse to no faster than one pulse every second.

If unit per pulse is set to 10 gallons per pulse,

the totalizer will pulse once every second.

Example for Setting the Totalizer

The following shows how to set the totalizer to track mass ow in kg/sec. (All outputs are

Conguration:

There are several possibilities regarding the measurement of water or steam energy given
the location of the meter and the use of a second RTD. The table below summarizes the
possibilities:

Fluid Meter Location Second RTD Measurement

Water “Sent” Flow Line “Return” Flow Line Change in Energy
Water “Return” Flow Line “Sent” Flow Line Change in Energy
Water “Sent” Flow Line None Outgoing Energy
Steam “Sent” Flow Line “Return” Flow Line (condensate) Change in Energy
Steam “Sent” Flow Line None Outgoing Energy

As above, you must properly congure the meter in the Energy Menu.

1. Loc in Sent Flow? Select Yes or No based on where the meter is located. Refer to the
above table.

2. Heating System? Select Yes for a hot water system used for heating. Select No for a
chilled water system used for cooling. Always select Yes for a steam system.

3. % Returned. Select a number between 0% and 100%. Estimate the amount of water
that returns. It is usually 100%, or can be less than 100% if historical data shows
the amount of makeup water used. If a second RTD is not used, set to 0%. When 0%
is selected, the energy calculation represents the outgoing energy only (no return
energy is subtracted).

IMPORTANT NOTICE

The meter ships from the factory assuming 0% return and has a 1000 ohm resistor installed in the
RTD #2 wiring location. This needs to be removed if the meter is to be used in a manner other than
with 0% return and with the customer supplied RTD in its place.

Use the Fluid Menu to congure the ow meter for use with common gases, liquids and
steam. Your ow meter is pre-programmed at the factory for your application’s process
uid.

Reference Richard W. Miller, Flow Measurement Engineering Handbook (Third Edition,

1996), page 2-75 for denition and use of the Goyal-Doraiswamy equation and page 2-76 for
the denition and use of the API 2540 equation. Also, see Appendix B for Fluid Calculation
equations.

The units of measurement used in the Fluid Menu are preset and are as follows:
Mole Weight = lbm/(lbm•mol), CRIT PRESS = psia, CRIT TEMP = °R, Density = kg /m3 and
Viscosity = cP (centipoise).

Use the Diagnostics Menu to simulate operation and review the system les. The
system log les contain time/date stamped messages including: power on, power off,
programming time outs, parameter faults, incorrect password entry and other various
information relative to system operation and programming.

The simulated inputs are for testing the meter to verify that the programming is correct.
They are also used to enter nominal operating temperature and pressure for the V
(volumetric) only model. Simulated vortex frequency allows you to enter any value for
the sensor input in Hz. The meter will calculate a ow rate based on the corresponding
value and update all analog outputs. The totalizer display and output is not affected by
a simulated frequency. The simulated pressure and temperature settings work the same
way. The meter will output these new values and will use them to calculate a new density
for mass ow measurement. Note: When your diagnostic work is complete, make sure to
return the values to zero to allow the electronics to use the actual transducer values. For
the V only model, keep the temperature and pressure at nominal operating conditions.
If the meter display indicates a temperature or pressure fault, a substitute value can be
entered to allow ow calculations to continue at a xed value until the source of the fault
is identied and corrected. The units of measure of the displayed values are the same as

the units congured for the ow meter.

4.1 HART COMMUNICATIONS

The HART Communications Protocol (Highway Addressable Remote Transducer Protocol) is a
bidirectional digital serial communications protocol. The HART signal is based on the Bell 202
standard and is superimposed on 4-20 mA Output 1. Peer-to-peer (analog / digital) and multi-drop
(digital only) modes are supported.

4.1.1 WIRING

The diagrams below detail the proper connections required for HART communications:

4.2.2 Menu Items

The following menu items are in the Output Menu and allow selection and control of the
Modbus communication protocol.

Address

When the Modbus protocol is selected, the Modbus address is equal to the user's
programmable device address if it is in the range 1…247 in accordance with the Modbus
specication. If the device address is zero or is greater than 247, then the Modbus address
is internally set to 1.

Comm Protocol

The Comm Protocol menu allows selection of “Modbus RTU Even,” “Modbus RTU Odd,”
or “Modbus RTU None2,” or “Modbus RTU None1,” (non-standard Modbus) with Even,
Odd and None referring to the parity selection. When even or odd parity is selected, the
unit is congured for 8 data bits, 1 parity bit and 1 stop bit; with no parity, the number of
stop bits is 1 (non-standard) or 2. When changing the protocol, the change is made as soon
as the Enter key is pressed.

Modbus Units

The Modbus Units menu is to control which units, where applicable, the meter’s variables
will be displayed in. Internal – (these are the base units of the meter, °F, psia, lbm/sec , ft3/
sec, Btu/sec , lbm/ft3 Display) – variables are displayed in user selected display unit.

Modbus Order

The byte order within registers and the order in which multiple registers containing
oating point or long integer data are transmitted may be changed with this menu item.
According to the Modbus specication, the most signicant byte of a register is transmitted
rst, followed by the least signicant byte. The Modbus specication does not prescribe
the order in which registers are transmitted when multiple registers represent values
longer than 16 bits. Using this menu item, the word order and byte order for oating point
and long integer values may be reversed to accommodate different Modbus operating
systems.

F-2600 & F-2700 Vortex Flow Meter Manual 02/15 - 0808-7 / 19204 Page 82

The following four selections are available in this menu. When selecting an item, the
protocol is changed immediately without having to press the ENTER key.

0-1:2-3 Most signicant register rst, most signicant byte rst (default)
2-3:0-1 Least signicant register rst, least signicant byte rst
1-0:3-2 Most signicant register rst, least signicant byte rst
3-2:1-0 Least signicant register rst, most signicant byte rst

Note that all of the registers are affected by the byte order, including strings and registers
representing 16-bit integers. The register order only affects the order of those registers
representing 32-bit oating point and long integer data, but does not affect single 16-bit
integers or strings.

Modbus Protocol

The Modbus RTU protocol is supported in this implementation. Supported baud rates are
1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200. The default baud rate is 19200
baud. Depending upon the Modbus protocol selected, data is transmitted in 8-bit data
frames with even or odd parity and 1 stop bit or no parity and 2 or 1 (non-standard) stop
bits.

Table 2. Byte Order

The current Modbus protocol specication does not dene register usage, but there is an
informal register numbering convention derived from the original (now obsolete) Modicon
Modbus protocol specication which is still used by many vendors of Modbus capable
products.

Each range of register numbers maps to a unique range of addresses that are determined by
the function code and the register number. The address is equal to the least signicant four
digits of the register number minus one, as shown in the following table.

Registers Function Codes Data Type and Address Range

00001-09999 01, 05, 15 Read/write bits 0000-9998

4.2.3 Register Denitions

The meter serial number and those variables that are commonly monitored (mass, volume
and energy ow rates, total, pressure, temperature, density, viscosity, Reynolds number,
and diagnostic variables such as frequency, velocity, gain, amplitude and lter setting) are
accessible via the Modbus protocol. Long integer and oating point numbers are accessed
as pairs of 16-bit registers in the register order selected in the Modbus Order menu.
Floating point numbers are formatted as single precision IEEE 754 oating point values.

The ow rate, temperature, pressure, and density variables may be accessed as either
the ow meter internal base units or in the user-programmed display units, which is
determined by the programming Output Menu’s “Modbus Units” item. The display units
strings may be examined by accessing their associated registers. Each of these units string
registers contain two characters of the string, and the strings may be two to 12 characters
in length with unused characters set to zero. Note that the byte order affects the order in
which the strings are transmitted. If the Modbus Order menu (see Section 4.2.2) is set to
0-1:2-3 or 2-3:0-1, then the characters are transmitted in the correct order. If set to 1-0:3-2
or 3-2:1-0, then each pair of characters will be transmitted in reverse order.

32013-32017 Energy ow units string — 03, 04 2012-2017

Function codes 03 (read holding registers) and 04 (read input registers) are the only codes
supported for reading these registers, and function codes for writing holding registers are
not implemented. We recommend that the oating point and long integer registers be read
in a single operation with the number of registers being a multiple of two. If this data is
read in two separate operations, each reading a single 16-bit register, then the value will
likely be invalid.

The oating point registers with values in display units are scaled to the same units as
are displayed, but are instantaneous values that are not smoothed. If display smoothing
is enabled (non-zero value entered in the Display TC item in the Display Menu), then the
register values will not agree exactly with the displayed values.

Exception Status Denitions

The Read Exception Status command (function code 07) returns the exception status byte,
which is dened as follows. This byte may be cleared by setting “coil” register #00003
(function code 5, address 2, data = 0xff00).

Bit(s) Denition

0-1 Byte order (see Modbus Order on page 2)

4 A/D converter fault
5 Period overow
6 Pulse overow
7 Conguration changed

Discrete Input Denitions

The status of the three alarms may be monitored via the Modbus Read Discrete Input
command (function code 02). The value returned indicates the state of the alarm, and will
be #1 only if the alarm is enabled and active. A zero value is transmitted for alarms that
are either disabled or inactive.

Control Register Denitions

The only writeable registers in this implementation are the Reset Exception Status, Reset
Meter and Reset Totalizer functions, which are implemented as ”coils” which may be
written with the Write Single Coil command (function code 05) to address 8 through 10,
respectively (register #00009 through #00011). The value sent with this command must be
either 0x0000 or 0xff00, or the meter will respond with an error message. The totalizer will
be reset or exception status cleared only with a value of 0xff00.

Error Responses

If an error is detected in the message received by the unit, the function code in the
response is the received function code with the most signicant bit set, and the data eld
will contain the exception code byte as follows:

Exception

Code

Description

01 Invalid function code — function code not supported by device

02

03

If the rst byte of a message is not equal to the unit’s Modbus address, if the unit detects a
parity error in any character in the received message (with even or odd parity enabled), or
if the message CRC is incorrect, the unit will not respond.

Command Message Format

The start address is equal to the desired rst register number minus one. The addresses
derived from the start address and the number of registers must all be mapped to valid
dened registers, or an invalid data address exception will occur.

Device Address

8 bits, 1...247

4.3 BACnet MS/TP Communications

4.3.1. BACnet MS/TP Description

The BACnet Master-Slave/Token-Passing (MSTP) driver implements a data link protocol that
uses the services of the RS-485 physical layer. The MS/TP bus is based on BACnet standard
protocol SSPC-135, Clause 9. BACnet MS/TP protocol is a peer-to-peer, multiple master
protocols based on token passing. Only master devices can receive the token, and only the
device holding the token is allowed to originate a message on the bus. The token is passed from
master device to master device using a small message. The token is passed in consecutive order
starting with the lowest address. Slave devices on the bus only communicate on the bus when
responding to a data request from a master device.

4.3.2. Baud Rates on the MS/TP Bus

An MS/TP bus can be congured to communicate at one of four different baud rates. It
is very important that all of the devices on an MS/TP bus communicate at the same baud
rate. The baud rate setting determines the rate at which devices communicate data over
the bus. The available baud rate settings available on F-2600 and F-2700 Flow Meters are
9600, 19200 and 38400.

4.3.2.1. Baud Rate and MAC address conguration

3. Give the factory password 16363 (Use Up and Down arrows to enter the digits)

4. Navigate to Diagnostics menu

5. Press Enter and press right button immediately

6. Navigate to Cong Code screen by continuous pressing down button

7. After reaching cong code screen, press right to navigate to Comm. Type screen

8. Change the comm. Type to “Modbus” and press Enter
Note: Modbus will enable Baud Rate and MAC address screens

9. Press Exit twice to reach Diagnostics menu back

10. Navigate to Output Menu by using right or left arrow buttons

11. Press Down button and reach Baud Rate and MAC address screens

12. Change the required settings and press Exit & Enter buttons to save the conguration

13. Do steps from b to g, and change the comm. Type as Hart.

14. Reboot the device by power off and on.

Note:

a. Baud rates are 9600, 19200 or 38400
b. MAC address range is 0-127

4.3.3. Supported BACnet Objects

A BACnet object represents physical or virtual equipment information, as a digital input
or parameters. ONICON F-2600 and F-2700 Flow Meters present the following object
types:

a. Device Object
b. Analog Input
c. Binary Input
d. Binary Value

Each object type denes a data structure composed by properties that allow the access
to the object information. The below table shows the implemented properties for each
Vortex Mass Flow Meters object type.
