IMPORTANT NOTICE
Use FTB690 Series meters with water and other
chemicals compatible with wetted components
(see Specifications Section). Do not use to
meter fuel or incompatible chemicals. FTB690
Series meters are available with either a local
electronic display, or a conditioned signal
output module to provide a digital signal to
customer interfacing equipment. FTB690
Series meters with computer display measure
in gallons or liters. Refer to the Calibration
Section for details.
These meters are not legal for trade applications.
FTB690 Series meters are very sensitive to
electric noise if operated within one to two
inches of some electric motors or other sources
of electronic noise.
INSTALLATION
Install your meter in-line either horizontally or
vertically or at the end of the hose adjacent to
the nozzle. Installation to metal connections is
not recommended. Install as follows:
1. Plan to install turbine with a minimum
straight pipe length as follows:
– Upstream from the turbine, allow a mini-
mum straight pipe length of 10 times
the internal diameter of the turbine.
– Downstream from the turbine, allow a
minimum straight pipe length of 5 times
the internal diameter of the turbine.
2. For NPT Fittings wrap all connections with
3 to 4 wraps of thread tape. Make sure the
tape does not intrude into the flow path.
3. Attach meter with arrow pointed in the
direction of flow.
4. For NPT Fittings - Hand tighten the meter
at the housing ends. Do not use a wrench
or similar tool to tighten. This can damage
the housing.
Conditioned Signal Output
Module Wiring
This conditioned signal output module can be
wired to provide an open collector signal output
or 6-volt square wave output.
When installing an FTB690 Series meter, the
correct K-factor must be entered into the readout
device. You can find the K-factor printed on the
turbine body. All K-factors on Omega flowmeters
are calculated in pulses per gallon (PPG).
Open Collector Signal Output
To achieve an open collector signal output,
reference Wiring Diagram 1. The terminal block
is located on the back side of the module. The
module is factory assembled for open collector signal output. Please provide the (820 ohm
minimum) resistor, if not supplied by receiving
equipment.
Ten feet (3 m) of cable is provided with the
module. Trim it to desired length or extend it as
necessary. Distances up to 5,000 feet (1,524 m)
can be achieved for open collector signal output.
Square Wave Output
To achieve square wave output, reference Wiring Diagram 2 and use an FLSC790-BATT (sold
separately) for battery power. The terminal block
and battery location are located on the back
side of the module. Access as follows:
1. Remove the four Phillips-head screws from
the front of the module and lift the module
from the turbine.
2. To change terminal block connections,
loosen the appropriate screws. Reconnect
the wires in the proper positions and tighten
the screws.

4. Position the module on the turbine housing.
To avoid moisture damage, make sure the
seal is fully seated. Tighten the four screws
on the front of the module.
Ten feet (3 m) of cable is provided with the
module. Trim the cable to desired length or
extend it as necessary.
Verify Meter Accuracy
Before using, check the meter’s accuracy and
verify calibration.
1. Make sure there is no air in the system
by starting the flow until it runs steadily.
Then, stop or divert the flow using a valve
or nozzle.
2. Hold down DISPLAY for 3 seconds to zero
the meter’s Batch Total. When zeros appear,
release the button.
3. Meter an exact known volume into an
accurate container. For best results, meter
with one continuous full stream.
4. Check the volume against the display
or recording equipment. If the amount
metered is accurate, field calibration is not
necessary. If not, refer to the Calibration
Section for further instructions.
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 flow 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 zeros must be added to
the 6 digits shown.
Press the DISPLAY button briefly to switch
between the TOTAL 1, TOTAL 2 BATCH and
FLOWRATE. Press DISPLAY briefly to display
the TOTAL 2 BATCH. Hold the DISPLAY button
for 3 seconds to reset the Batch Total to zero.
When fluid is flowing through the meter, a small
propeller icon is highlighted.
Flowrate Feature
To use this feature, press and release DISPLAY
button 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 flow.
OPERATION
Computer Display
All operations are reflected in the LCD readout.
The large center digits indicate amounts, where
smaller words or “icons” located above and
below indicate specific information regarding
totals, flow, calibration and units of measure.
Activate the Meter
Computer is on continuously and always ready
to perform. The computer is powered by field
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.
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 configured with a “factory” calibration. Both gallons and liters are available (“GL” or
“LT” will be displayed). While holding the CALIBRATE button, briefly 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).
3
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).
The “field” calibration may be set by the user,
and can be changed or modified at any time
using the calibration procedure described below
in the Calibration Section. Totals or flowrate
derived from the field calibration are invoked
when the FAC icon is no longer visible on the
top line of the display.
CALIBRATION
Verify Accuracy Before
Beginning Field Calibration
For the most accurate results, dispense at
a flowrate which best simulates your actual
operating conditions. Avoid “dribbling” more
fluid or repeatedly starting and stopping the
flow. This can result in less accurate calibrations.
Make sure you meet the meter’s minimum
flowrate requirements:
FTB690A Series Meters
1/2 inch meter 1 GPM (3.8 LPM)
3/4 inch meter 2 GPM (7.5 LPM)
1 inch meter 5 GPM (18.9 LPM)
1-1/2 inch meter 10 GPM (37.9 LPM)
2 inch meter 20 GPM (75 LPM)
The use of a uniformly dependable, accurate
calibration container is recommended for the
most accurate results. Due to high flowrate, it
is strongly recommended that calibration be
completed with a combination of volume and
weight using fine resolution scales. For best
results, the meter should be installed and purged
of air before field calibration.
Field Calibration Procedures
(Dispense/Display Method)
1. To field calibrate, press and hold 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 field calibration mode.
2. Dispense a known amount of fluid at a
flowrate representative of the application.
Any amount between .1 and 999.9 units
can be used. Display will count up while
fluid is flowing 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 satisfied 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 above
dispense procedure. No unit of measure
(gallon, litre, etc.) icon will be highlighted.
NOTE: To return to factory calibration (FAC),
press and hold both CALIBRATION and
DISPLAY buttons for about 3 seconds, until
FAcCAL is displayed. Then release buttons.
Unit should return to normal operation and
FAC icon visible.
NOTE: If the field calibration mode is entered
and NO fluid is dispensed, then upon leaving, the computer will use data from the last
successful field calibration.
Field Calibration with
Computer Display
Field Calibration and Factory Calibration are
defined in the Operation Section. Factory
calibration settings are programmed into each
computer during manufacturing, using water
at 70° F (21° C). Readings using the Factory
Calibration (FAC) may not be accurate in some
situations, for example, under extreme temperature conditions, non-standard plumbing
configurations or with fluids other than water.

MAINTENANCE
SPECIFICATIONS
Proper handling and care will extend the life
and service of the meter.
Turbine Rotor
The meter is virtually maintenance-free.
However, it is important the rotor moves freely.
Keep the meter clean and free of contaminants.
If the rotor does not turn freely, apply a penetrating lubricant on the rotor, shaft, and bearings.
Remove any debris or deposits from the rotor
using a soft brush or small probe. Be careful not
to damage the turbine rotor or supports.
CAUTION
Blowing compressed air through the turbine
assembly could damage the rotor.
Battery Replacement
The computer display is powered by two 3-volt
lithium batteries which may be replaced while
the meter is installed. When batteries are
removed or lose power, the batch and cumulative totals and the field and factory calibrations
are re tained.
If the display becomes dim, blank or the low
battery message appears (see below), replace
the batteries as follows:
1. Remove the four Phillips-head screws from
the face of the meter and lift the faceplate
from the turbine.
2. Remove the old batteries and clean any
corrosion from the terminals.
3. Install new batteries. Make sure the positive
post is in the correct position.
4. When the batteries are replaced, the faceplate will power ON. Check the display to
ensure normal functions have resumed
before assembling again.
5. Reseat batteries, if necessary, and position
the faceplate on the turbine housing.
To avoid moisture damage, make sure the
seal is fully seated. Tighten the four screws
on the faceplate.
