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 Flow Monitors come pre­calibrated, from the factory, if ordered with an Omega FTB-1400  ow 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.

OPERATING THE MONITOR

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 – Switches to Program mode

UP Arrow – Scrolls forward through the parameter choices and

increments numeric variables

RIGHT Arrow – Scrolls backward through the parameter choices and
moves the active digit to the right

ENTER – Used to save programming information, advance to the next
programming parameter, and in the reset process

Modes:

RUN – Normal operating mode

PROGRAM – Used to program variables into the display

If your monitor was ordered with an Omega FTB-1400  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.

6

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 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.

SELECT THE METER SIZE – At the METER prompt, press the UP or
RIGHT arrow keys to select the bore size of your meter. Press ENTER
button once to save meter size choice and advance to the K-factor
units selection.

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”
up to 1”. Be sure to use the correct bore size or the meter will report incorrect
 ows and totals.

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.

NOTE: Unless otherwise speci ed, Omega FTB-1400 turbine  ow meters
are supplied with K-factors measured in pulses per gallon (PUL/GAL) which
will automatically convert to your desired units of measure.

NOTE: The K-factor supplied with the meter or calculated from calibration
data will be needed to complete next step.

ENTER THE METER’S K-FACTOR – To change the K-FACTOR value, use
the RIGHT arrow key and select the position of the number that you
wish to change. Using the UP arrow key, increment the display digit
until it matches the meter’s K-factor digit. Repeat this process until all
K-factor digits have been entered. Press ENTER once to save the actor
and advance to the RATE/TOTAL units selection.

8

SELECT THE RATE/TOTAL UNITS OF MEASURE – The monitor allows
the choice of  ve common rate/total units. The monitor shows the
current rate/total unit. If the current selection is correct, press the
ENTER key once 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.

Selection Rate Total

GPM/GAL Gallons per Minute Gallons

LPM/LIT Liters per Minute Liters

M3PH/M3 Cubic Meters per Hour Cubic Meters

M3PD/M3 Cubic Meters per Day Cubic Meters

BPD/BBL Oil Barrels per Day Oil Barrels

NOTE: The total unit’s output multiplier cannot be modi ed in the Simpli ed
program level. This option is reserved in the Advanced program level.

SELECT THE DISPLAY FUNCTION – The monitor can display RATE or
TOTAL or alternate between BOTH rate and total. 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.

A TEST function is also available in the Display Function sub-menu. With
the test function selected, the display acts like a frequency counter and
displays the raw input frequency being supplied to the frequency input
terminals. This is very useful when troubleshooting  ow problems.

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. 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.

PASSWORD – Password protection prevents unauthorized users from
changing programming information. Initially, the password is set to
all zeros. To change the password, simply enter any 4 digit code using
the arrow keys as previously described to 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.

9

RST PSWD – The reset password screen allows the operator to enter
any 4 digit code for the manual reset totals function.

NOTE: This reset password code will not allow the operator to enter the
programming mode.

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 reset procedure.

STORE TOTAL – The current total can be manually stored in the
monitor’s  ash memory. This procedure may be desirable prior to
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.

10

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 turbine  ow meters utilize a magnetic pick-up, the FTB-1400 Flow
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 12.

• Check battery voltage. Should be 1.5 Vdc. Replace if low
or bad.

• Check connection from meter pick-up to display input
terminals.

• Check turbine meter rotor for debris. Rotor should spin
freely.

• Check programming of  ow monitor.

• This is usually an indication of external noise. Keep all
AC wires separate from DC wires.

• Check for large motors close to the meter pick-up.

• Check for radio antenna in close proximity.

• Try disconnecting the pick-up from the monitor pig tail.
This should stop the noise.

• This usually indicates a weak signal. Replace pick-up
and/or check all connections.

• Examine K-factor.
