Product Description

Omega Industrial Meter Turbines are

identied by the internal diameter of

the inlet and outlet.

FTB891 - 1/2 inch
FTB893 - 1 inch
Each turbine is designed to work with
on-

board computer electronics and/
or with one of several accessory mod­ules that can interface to a wide vari­ety of reporting and collecting devices.

The CMOS microprocessor-based

electronics have extremely low power

requirements and data retention
capabilities in both RAM and ROM.
Information is clearly displayed on a
large 6-digit LCD readout with two-

point oating decimal for totals from

.01 to 999,999. All operations are
easily accessed with the two buttons
on the front panel.

Liquid ows through the turbine hous­ing causing an internal rotor to spin.
As the rotor spins, an electrical signal
is generated in the pickup coil. The
electrical signal provides the output
necessary to operate the on-board
computer electronics for local indication
directly on the turbine or one of several
accessory modules that transmit the

signal to external equipment.

Upon receipt, examine your meter

for visible damage. The turbine is a
precision measuring instrument and
should be handled as such. Remove
the protective plugs and caps for a
thorough inspection. If any items are
damaged or missing, contact your
distributor.

Make sure the turbine model meets

your specic needs. Refer to the
Specications Section and conrm

the following:

1. The owrate is within the limits of

your model.

2. The liquid is compatible with the
turbine’s wetted components.

3. The system’s pressure does not

exceed the turbine’s maximum

pressure rating.

Each Omega Turbine has a unique

identication number that includes

the Serial Number, Model Number,
Manufacturing Date, and K-Factor.

This identication number is etched

into the surface of the turbine. Record

this identication number in the back

of the Owner’s Manual and keep for
future reference.

2

SN = Serial Number, a 7-8 dig-

it number that identifies this
particular turbine.

MOD = Model number

KF = K-Factor given in pulses per

gallon (PPG).

MFD = Manufacturing Date indicating

the week and year of manufac­ture.

INSTALLATION

All Omega turbines are designed to

measure ow in only one direction.

The direction is indicated by the arrow
cast-molded in the turbine outlet. If the
opposite direction is desired, and you
are using on-board computer electron­ics, rotate the computer electronics 180
degrees prior to installation.

Flow altering devices such as elbows,
valves, and reducers can affect ac­curacy. The following recommended
guidelines are given to enhance ac-

curacy and maximize performance.

Distances given here are minimum
requirements; double them for desired
straight pipe lengths.

Upstream from the turbine, allow a
minimum straight pipe length at least
10 times the internal diameter of the

turbine. For example, with the FTB893

turbine, there should be 10 inches (25.4
cm) of straight pipe immediately up­stream. The desired upstream straight
pipe length is 20 inches (50.8 cm).

Downstream from the turbine, allow a
minimum straight pipe length at least
5 times the internal diameter of your

turbine. For example, with the FTB893

turbine, there should be 5 inches
(12.7 cm) of straight pipe immediately
downstream. The desired downstream
distance is 10 inches (25.4 cm).

A typical back pressure of 5 to 50 PSI
(0.34 to 3.4 bar) will prevent cavitation.
Create back pressure by installing a
control valve on the downstream side

of the meter at the proper distance
detailed above.

Foreign material in the liquid being
measured can clog the turbine’s rotor
and adversely affect accuracy. If this

problem is anticipated or experienced,
install screens to lter impurities from

incoming liquids.

The PVDF Series FTB890 turbines
are Factory Mutual Approved and
carry a Class 1, Division 1 Approval
for hazardous environments. Omega
Meters are tested and calibrated at the
factory using state-of-the-art calibra­tion test equipment.

To ensure accurate measurement,
remove all air from the system before
use. To purge the system of air:

1. Ensure some back pressure on
the turbine.

2. Open the discharge valve or nozzle

and allow uid to completely ll the

system. Make sure the stream is
full and steady.

3. Close the discharge valve or
nozzle.

4. Start normal operations.

Each turbine contains a removable
back coverplate. Leave the coverplate
installed unless accessory modules
specify removal.

3

Connections

1. To protect against leakage, seal
all threads with an appropriate
sealing compound. Make sure
the sealing compound does not

intrude into the ow path.

2. Make sure the ow direction arrow

on housing back is pointed in the

direction of the ow.

3. Install union ring over pipe end

prior to installing pipe tting.

4. Install pipe ttings on pipe ends,

and tighten.

5. Tighten union ring to the turbine.
Make sure O-ring is positioned in
housing ends. Do not use a wrench
or pliers. Hand tighten only.

NOTE: If connecting to new male

threads, burrs and curls can
adversely affect accuracy. Cor­rect the problem prior to turbine
installation.

It is strongly recommended that ac-

curacy be veried prior to use. To do

this, remove all air from the system,

measure an exact known volume into

an accurate container, and verify the
volume against the readout or record­ing equipment. If necessary, use a

correction factor to gure nal volume.

For best results, accuracy should be

veried periodically as part of a routine

maintenance schedule. The procedure
is found in the Maintenance Section.

The display electronics is normally
installed on the turbine housing at the
factory unless ordered without it.

If for any reason the display electronics
need to be mounted on your turbine,
simply mount the display on the turbine
with the four screws at the corners
of the faceplate. Make sure the seal
is fully seated before tightening the
screws.

If you ordered the FTB890 Series
turbine with an accessory module,
please review and thoroughly under-

stand all installation instructions before
proceeding.

Avoid electronically “noisy” environ­ments. Install at least 6 inches (15.2
cm) away from motors, relays, or
transformers.

OPERATION

Computer Display

All operations are reected in the

LCD readout. The large center digits
indicate amounts, where smaller words
or “icons” located above and below

indicate spcic information regarding
totals, ow, calibration and units of

measure.

Activate the Meter

Computer is on continuously and al­ways ready to perform. The computer
is powered by eld replaceable batter­ies. When display becomes dim, faded
or the low battery message appears
(see below), the batteries need to be
replaced. Reference the Maintenance
Section for details.

Batch and Cumulative Totals

The computer maintains two totals.
The Cumulative Total provides con­tinuous measurement and cannot be
manually reset. The Batch Total can be

reset to measure ow during a single

use. The Cumulative Total is labeled
TOTAL 1, Batch Total is labeled TOTAL
2 BATCH.

When the Cumulative Total reaches a
display reading of 999,999 the com­puter will highlight an X10 icon. This
indicates to the operator that a zero
must be added to the 6 digits shown.

When the next rollover occurs, the

computer will highlight an X100 icon.
This indicates to the operator that
two zeroes must be added to the 6
digits shown.

4

Press the DISPLAY button briey to

switch between the TOTAL 1, TOTAL
2 BATCH and FLOWRATE. Press

DISPLAY briey to display the TOTAL 2

BATCH. Hold the DISPLAY button for 3
seconds to reset the Batch Total to zero.

When uid is owing through the meter,

a small propeller icon is highlighted.

The “eld” calibration may be set by the
user, and can be changed or modied

at any time using the calibration proce­dure described below in the Calibration

Section. Totals or owrate derived from
the eld calibration are invoked when

the FAC icon is no longer visible on
the top line of the display.

Flowrate Feature

To use this feature, press and release
DISPLAY until FLOWRATE icon ap­pears. The factory set time base will be
highlighted to the right of FLOWRATE
(M = minutes, H = hours, D = days).
When FLOWRATE is invoked, the

display will be indicating rate of ow.

Factory and Field Calibration

All calibration information is visible to
the user as icons on the top line of
the display, above the numeric digits.

All units are congured with a “factory”

calibration. Both gallons and litres
are available (“GL” or “LT” will be dis­played). While holding the CALIBRATE

button, briey press DISPLAY to toggle

between gallons and litres. This fac­tory calibration (indicated with FAC)
is permanently programmed into the
computer and is not user adjustable.

NOTE: Your computer may have other

units of measure programmed into
it. If so, holding the CALIBRATE
button and momentarily pressing
the DISPLAY button will toggle
through all factory set units. Other
possible units are: IGL (imperial
gallon), QT (quart), CF (cubic feet),
CM (cubic meter), BL (42 gal.
barrel), CC (cubic centimeter) or
OZ (ounce).

Switching between different units will
not corrupt the Total’s contents. For

example, in GL mode, the computer

totalizes 10.00 gallons, if the user
switches to LT mode, the display will
read 37.85 litres (the same volume,
different unit).

CALIBRATION

Verify Accuracy Before
Beginning Field Calibration

For the most accurate results, dis­pense at a owrate which best simu­lates your actual operating conditions.

Avoid “dribbling” more uid or repeat­edly starting and stopping the ow. This

can result in less accurate calibrations.

Make sure you meet the meter’s mini-

mum owrate requirements:

1/2 inch meter 0.6 GPM (2.2 LPM)
1 inch meter 2.5 GPM (9.5 LPM)

The use of a uniformly dependable,
accurate calibration container is
recommended for the most accurate
results. For best results, the meter
should be installed and purged of air

before eld calibration.

Field Calibration with
Computer Display

Field Calibration and Factory Cali-

bration are dened in the Operation

Section. Factory calibration settings
are programmed into each computer
during manufacturing, using Stoddard
test solvent at 70° F (21° C). Settings
are correct for light liquids such as
water, gasoline or diesel. Readings
using the Factory Calibration (FAC)
may not be accurate in some situations,

for example, “heavy” liquids such as
motor oil under extreme temperature

conditions, non-standard plumbing

congurations or with uids other than

those mentioned above.

5

For improved accuracy under such
conditions, the computer allows for

“eld” calibration, that is, user entry

of custom calibration parameters. A
“single point” calibration may yield
acceptable accuracy when used in a
non-standard application.

Field Calibration Procedures
(Dispense/Display Method)

1. To eld calibrate, press and hold

the CALIBRATE and DISPLAY
buttons for about 3 seconds until
you see FLdCAL. Release both
buttons and you will see dd000.0.

You are now in the eld calibration

mode.

2. Dispense a known amount of uid
at a owrate representative of the

application. Any amount between
.1 and 999.9 units can be used.

Display will count up while uid is
owing through the meter.

3. The DISPLAY button can then be
pushed to select the digit location
and the CALIBRATE button can be
pushed to scroll the desired value
at the blinking position. Edit the
amount shown with the value that
was dispensed above. Values from

000.1 to 999.9 can be entered.

4. When satised with the value,

press both CALIBRATE and
DISPLAY buttons simultaneously.
CALEnd will be displayed and unit
will go back to normal operation,
less the FAC (factory calibration)
icon.

5. The meter will now be operating
with a custom calibration number
unique to the dispense procedure.
No unit of measure (gallon, litre,
etc.) icon will be highlighted.

NOTE: To return to factory calibra-

tion (FAC), press and hold both
CALIBRATION and DISPLAY
buttons for about 3 seconds,
until FAcCAL is displayed. Then
release buttons. Unit should re-

turn to normal operation and FAC
icon is visible.

NOTE: If the eld calibration mode is

entered and NO uid is dispensed,

then upon leaving, the computer
will use data from the last success-

ful eld calibration.

MAINTENANCE

Verify Accuracy

Before use, check the turbine’s ac­curacy and verify calibration.

1. Make sure there is no air in the
system.

2. Measure an exact known volume

into an accurate container.

3. Verify the volume against the
readout or recording equipment.

NOTE: If necessary, use a correction

factor to gure nal volume.

For best results, accuracy should be

veried periodically as part of a routine

maintenance schedule.

Remove the Turbine

WARNING

During turbine removal, liquid may spill.
Follow the liquid manufacturer’s safety
precautions for clean up of minor spills.

1. Ensure all liquid is drained from the
turbine. Wear protective clothing as
necessary.

2. Loosen both union rings at the
ends of the turbine.

3. If the turbine is not immediately
installed again, cap lines as nec­essary.

Replace Internal Parts

1. Remove the turbine from the sys­tem. See Figure 5.

detailed above. Note orientation
carefully for correct assembly.
Internal parts can be soaked for
10 to 15 minutes in compatible
cleaning solutions. Use a soft
brush or small probe to carefully
remove residue from the rotor.

Turbine Housing

2. Use your ngers to gently re­move the rotor assembly from
the groove. Do not use force to
remove the rotor assembly.

CAUTION

Handle the rotor carefully. Even small
scratches or nicks can affect accuracy.

3. Use the procedure below to clean
the turbine.

4. Install the rotor assembly into the
turbine housing. Make sure the
pointed end of the rotor assembly is

inserted rst. (see Figure 5) Guide

the assembly into place using a
smooth motion, little or no force is
required.

5. Reinstall the turbine, purge the
system of air, and verify accuracy
before use.

Clean the Turbine

During use, the turbine should be kept
full of liquid to ensure that drying does
not occur inside the turbine. If drying
or caking should occur, the rotor will
stick or drag, affecting accuracy. To
determine if the rotor is stuck or drag­ging, remove rotor from housing and
physically turn rotor.

CAUTION

Never blow compressed air through the
meter. It could damage the rotor.

1. Remove the turbine from the sys­tem following the directions above.

2. Carefully clean residue off all

WARNING

Follow the liquid manufacturer’s
instructions for the disposal of
contaminated cleaning solvents.

3. When the rotor turns freely, assemble
and install it again following the instruc­tions above.

Display Electronics

The display electronics are powered
by lithium batteries. If the meter’s
readout should become dim, blank
or the low battery message appears
(see below), the batteries should be
replaced. Replacement batteries can
be ordered from the factory. See details
in the Parts Section.

When batteries are disconnected or
fail, the Batch and Cumulative Totals
values will remain. Factory and Field
Calibration Curves are retained in the
meter’s computer when power is lost.

It is strongly recommended that battery
check and terminal cleaning be a part
of a routine maintenance schedule.
Battery terminals should be cleaned
annually. Batteries can be replaced
without removing the meter from the
piping system.

Replacing the Batteries

1. Remove the corner screws from
the meter face and lift the display
electronics from the turbine.

2. Remove the batteries.

the same effect as initial power
up and zeroes out all totalizers.

J-2 Pulse Signal Output

This supplies a high-level ampli-

ed open collector signal. Output
will withstand a maximum open-

circuit voltage of 60 volts DC

and a maximum closed-circuit

of 100 mA.

J-4 Pulse Signal Input

Requires a sine or square wave
with open-circuit voltage of 3-30

volts P-P, a maximum rise/fall

rate of 0.01 V/µ second and a

maximum frequency of 750 Hz.

J-5 Power Input

When used with Ground (J1-6),
this has reverse polarity protec­tion, but no on-board voltage
regulation. Supplied voltage must
be 5.75 volts DC ±5%.
