INTRODUCTION
The FTB-1400 Flow Monitor is a state-of-the-art, digital signal processing
ow monitor, designed to provide the user with exceptional exibility at a
very a ordable price. Though designed for use with Omega FTB-1400 ow
meters, this display can be used with almost any ow meter producing a
low amplitude AC output or contact closure signal(s).
This ow monitor is capable of accepting a low-level frequency input for
calculating ow rate and total. These calculations can then be displayed
in the desired units of measurement. All FTB-1400 ow monitors come
pre-calibrated, from the factory, if ordered with an Omega FTB-1400 Flow
Meter. If required, however, it can easily be re-con gured in the eld.
The monitor’s large 8 digit by .75" numeric liquid crystal display makes
extended range viewing practical. The second 8 digit by .38" alphanumeric
display provides for selectable units viewing in run mode and prompts for
variables in program mode. Finally, the user can choose between displaying
rate, total, or alternating between both rate and total.

The monitor has two modes of operation referred to as the RUN mode and
the PROGRAM mode. Both the run mode and the program mode display
screen enunciators con rming the state of the monitor. A quick glance at
the lower left hand corner of the LCD screen will con rm operating status.
Normal operation will be in the RUN mode. To access the program mode,
press the MENU button until the rst programming screen is displayed.
After programming the display with the necessary information, a lock out
feature can be turned on to prevent unauthorized access or changing the
meter’s setup parameters.
BASIC PROGRAMMING MODE
Keys:
MENU – Switch between RUN and PROGRAM modes
UP Arrow – Scrolls through programming sub-menus in forward
direction and increments numeric variables
RIGHT Arrow – Scrolls through programming sub-menus in reverse
direction and moves the active digit to the right
ENTER – Used to enter sub-menus, save programming information and
in the reset process
If your monitor was ordered with an Omega ow meter, the two components
ship from the factory calibrated as a set. If the monitor is a replacement,
the turbine’s K-factor has changed, or the monitor is being used with some
other pulse generating device, programming will be necessary.
PROGRAMMING USING PULSE OUTPUT TURBINE
FLOW METERS
Each turbine ow meter is shipped with either a K-factor value or frequency
data. If frequency data is provided, the data must be converted to a K-factor
before programming; otherwise, 10 Point Linearization must be used to
program the monitor. K-factor information, when supplied, can usually be
found on the neck of the ow meter or stamped on the body. The K-factor
represents the number of pulses per unit of volume. The K-factor will be
needed to program the monitor readout.

ENTER PROGRAM MODE – Change to program mode by pressing
the MENU button once. The mode indicator will change from RUN to
PROGRAM.
NOTE: If any input value exceeds the meter's capabilities for that particular
parameter, the LIMIT indicator will begin to ash indicating an invalid entry.
Press ENTER once to return to the parameter’s entry screen to reenter the
value.
SELECT THE METER SIZE – At the METER prompt, press the ENTER
button once. The current meter size number will begin to ash. Using
the arrow keys, scroll through the size choices until you nd the bore
size of your meter. Press ENTER once to save the meter size choice.
NOTE: The meter connection size and the bore size are di erent. For
example, many of the 1” NPT turbines have bore sizes that range from 3⁄8”

SELECT THE DISPLAY FUNCTION – The monitor can display RATE
or TOTAL or alternate between BOTH rate and total. At the DISPLAY
prompt, press the ENTER key once. The monitor now shows the display
mode currently in e ect. If the current selection is correct, press the
ENTER key to advance to the next parameter. To change to an alternate
display mode, use the arrow keys to scroll to the desired display mode
and press ENTER to save the choice.
SELECT THE RATE UNITS OF MEASURE – The monitor allows the
choice of many common rate units. (See Speci cations for a complete
listing of the unit choices.) At the RATE UNT prompt, press the ENTER
key once. The monitor now shows the rate units of measure the display
is currently set for. If the current selection is correct, press the ENTER
key to advance to the next parameter. To change to an alternate unit,
use the arrow keys to scroll to the desired rate unit and press ENTER to
save the choice.
SELECT THE RATE [TIME] INTERVAL – The term Rate implies that
something is occurring over a period of time. Most people are familiar
with the rate of speed of a car reported in miles per hour (MPH). The
same concept holds true for a ow meter. The time choices are SEC
(seconds), MIN (minutes), HOUR (hours), and DAY (days). At the RATE
INT prompt, press the ENTER key once. The monitor now shows the
time interval the display is currently set for. If the current selection
is correct, press the ENTER key to advance to the next parameter. To
change to an alternate time interval, use the arrow keys to scroll to the
desired time interval and press ENTER to save the choice.
NOTE: If ow rate is the only measurement of interest, skip to KFAC UNT to
complete the programming process.
SELECT THE TOTAL UNITS OF MEASURE – If a ow amount is desirable,
the units for the total must rst be chosen. The monitor allows the
choice of many common totalization units. (See Speci cations for
a complete listing.) At the TOTL UNT prompt, press the ENTER key
once. The monitor now shows the total units of measure the display is
currently set for. If the current selection is correct, press the ENTER key
to advance to the next parameter. To change to an alternate unit, use
the arrow keys to scroll to the desired totalization unit and press ENTER
to save the choice.
NOTE: This unit of measure does not have to re ect the rate unit you have
previously chosen.
(Example: Rate Units = Gallons, Total Units = Barrels).

Page 10
SELECT THE TOTAL’S DISPLAY MULTIPLIER – The monitor has a very
versatile display that has the ability to accumulate the ow total in
multiples of ten. For example, if the most desirable totalization unit is
1,000 gallons, the monitor can easily be set up for this requirement.
Once the unit is back in RUN mode, every time the total display is
incremented by one digit the actual total would be an additional 1,000
gallons. At 1,000 gallons the total display would read 1, at 3,000 gallons
the total display would read 3, etc. This feature eliminates having to
look at a total, counting the digits and mentally inserting commas for
each 1000 multiple.
At the TOTL MUL [Multiple] prompt, press the ENTER key once. The
monitor now shows the multiplier the total display is currently set for.
If the current selection is correct, press the ENTER key to advance to
the next parameter. To change to an alternate multiplier, use the arrow
keys to scroll to the desired multiplier unit and press ENTER to save the
choice.
NOTE: Unless otherwise speci ed, Omega FTB-1400 turbine ow meters
are supplied with K-factors measured in pulses per gallon (PUL/GAL).
ENTER THE METER’S K-FACTOR UNIT – Directly after the METER size is
selected, the display’s K-factor unit must be chosen. Use the UP arrow
key to select your K-factor unit. For meters calibrated in gallons, use
PUL/GAL (pulses per gallon); for meters calibrated in cubic meters, use
PUL/M3 (pulses per cubic meter), etc. Press ENTER to save the K-factor
unit and advance to the next parameter.
SCALE FACTOR – At the SCALE F prompt, press the ENTER key once. The
current Scale Factor will begin to ash. If the current selection is correct,
press the ENTER key to advance to the next parameter. The scale factor
is used to force a global change to all variables. For example, under
operating conditions the display is reading a consistent 3% below the
expected values at all ow rates. Rather than changing all parameters
individually, the scale factor can be used to compensate for the 3%
o set. The scale factor would be set to 1.03 to correct the readings. The
range of scale factors is from 0.5 to 1.5. The default scale factor is 1.00.
10
Page 11
METER TYPE – At the METERTYP prompt, press the ENTER key once.
The current meter type will be displayed as “Liquid” or “GAS”. If the
current selection is correct, press the ENTER key to advance to the next
parameter. If “GAS” is selected you must then enter your Operating
Pressure and Operating Temperature before advancing to the next
parameter.
DAMPING FACTOR – At the DAMPING prompt, press the ENTER key
once. The current Damping setting will begin to ash. If the current
selection is correct, press the ENTER key to advance to the next
parameter. The Damping Factor is increased to enhance the stability
of the ow readings. Damping values are decreased to allow the ow
meter to react faster to changing values of ow. This parameter can
take on any value between 0 and 99 with 0 being the default.
TOTALIZER PULSE OUTPUT – The pulse output parameter can be
either enabled or disabled. When enabled this output generates 20mS
duration pulse for every time the least signi cant digit of the totalizer
increments (20Hz Max). The amplitude of the pulse is dependent on
the voltage level of the supply connected to the pulse output and is
limited to a maximum 30 VDC.
LINEARIZATION – Enhanced accuracy can be obtained by linearization
of the display. The linearization routine will accept a maximum of ten
points. Linearization requires additional calibration data from the
meter to be used with the monitor. Typically, calibration information
can be obtained in three, ve, and ten points from the ow meter’s
manufacturer. If linearization is not needed, pressing the RIGHT arrow
key will take you to the next parameter
Number of Points – At the LINEAR prompt, press ENTER once. The
NUM PTS number will be displayed. Press ENTER to set the number
of points you wish to use. Again, the UP arrow key increments
the value and the RIGHT arrow moves the cursor between digits.
When the number of points has been input, press the ENTER key
once to move to the rst linear segment.
Press the ENTER key once and the rst linear point’s frequency
input will begin to ash (FREQ 1). Enter the frequency for the rst
linear point using the arrow keys. When the frequency value input
has been completed, press ENTER once again to change to the
coe cient value for the rst linear point.
11
Page 12
The coe cient is the value applied to the nominal K-factor to
correct it to the exact K-factor for that point. The coe cient is
calculated by dividing the actual K-factor for that point by the
average K-factor for the ow meter.
Coe cient = Actual K-factor ÷ Average K-factor
At the COEFF prompt, enter the coe cient that corresponds to the
frequency value previously entered. Press ENTER once to move to
the next scaling point.
Continue entering pairs of frequency and coe cient points until
all data has been entered. Press the MENU key twice at the NUM
PTS prompts to exit to the LINEAR prompt. Press the RIGHT arrow
key to move to the next parameter.
PASSWORD – Password protection prevents unauthorized users from
changing programming information. Initially, the password is set to
all zeros. To change the password, press ENTER once at the password
prompt. The rst digit of the password value will begin to ash. Using
the arrow keys as previously described, enter the password value.
Pressing ENTER once will store the password and take you back to the
RST PSWD screen.
NOTE: This password will allow the operator to manually reset totals.
RST PSWD – Reset Password protection prevents unauthorized
users from manually resetting the ow monitor’s accumulated totals.
Initially, the password is set to all zeros. To change the password, press
ENTER once at the password prompt. The rst digit of the password
value will begin to ash. Using the arrow keys as previously described,
enter the password value. Pressing ENTER once will store the password
and take you back to the METER size screen, pressing MENU exits the
program mode. The FTB-1400 Flow Monitor is now ready for use with its
companion meter. Note: Entering a password in the Password screen
and leaving the password blank in the RST PSWD screen would allow
for total resets (not requiring password) and restrict programming
modi cation.
RESET TOTAL – To reset the monitor total display, in run mode press
the MENU and ENTER simultaneously until TOTAL RST starts to ash.
The TOTAL RST will stop ashing and the display will return to the run
mode at the conclusion of the procedure.
12
Page 13
STORE TOTAL – The current total can be manually stored in the monitor’s
ash memory. This procedure may be desirable prior to changing the
settings or replacing the battery. Press and hold the ENTER key for 2
seconds. The display will respond with a ashing TOTALSVD and then
return to the run mode.
AUTOMATIC STORE TOTAL – The monitor is equipped with a store
total feature that works automatically, saving the current total to ash
memory once per hour and just before a low battery condition turns
the unit o .
BATTERY REPLACEMENT
Battery powered monitors use a single 1.5V, “D” size, alkaline battery. When
replacement is necessary, use a clean fresh battery to ensure continued
trouble-free operation. It is recommended that the total be saved to
memory before the battery is removed. (See STORE TOTAL above.)
Unscrew the two captive screws on the front panel to gain access to the
battery. Replace the battery being sure to observe the proper polarity, and
then re-fasten the front panel.
ADDITIONAL INPUT OPTIONS
The FTB-1400 Flow Monitor is capable of receiving magnetic pick-up input
(small signal sine wave) or a contact closure input (pulse). Since Omega
FTB-1400 Flow Meters utilize a magnetic pick-up, the monitor is shipped
con gured for magnetic pick-up input. To change to a contact closure
input, remove JP2 from the top two pins and jumper them to the bottom
two pins. See Figure 3 on page 14.
