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.

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 – 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.

ADVANCED PROGRAMMING MODE

PROGRAMMING

EACH TURBINE FLOW 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 FLOW 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.

7

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

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.

9

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).

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.

Multiplier Choices – 0.01, 0.1, 1, 10, 100, 1000, 10000, 100000, and
1000000 Units.

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

10

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.

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 20 mS
duration pulse for every time the least signicant digit of the totalizer
increments (20 Hz 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.

FLOW 4 mA SETTING – When the loop powered option is ordered, the
ow rate that corresponds to 4 mA must be set. If the current selec­tion is correct, press the RIGHT arrow key once to advance to the next
parameter. If adjustment is required, press the ENTER key once at the
FLOW 4MA prompt. The most signicant digit will begin to ash. The
RIGHT arrow key moves the active digit one place to the right for each
press of the key. The UP arrow key increments the active digit one in­teger for each press of the key. When the correct 4 mA ow rate has
been entered, press ENTER once to store this value and move to the
next parameter.

FLOW 20 mA SETTING – Follow the same programming process as the
FLOW 4MA except for the ow rate setting. In this case, use the maxi­mum ow rate for the meter.

11

4-20 mA CALIBRATION – When ordered with a 4-20 mA option, this
menu item allows the ne adjustment of the 4-20 mA output. The 4 mA
setting is typically between 35 and 50. To set the 4 mA value, connect
an ammeter in series with the loop power supply. See Figure 3. At the
4-20CAL prompt, press ENTER once. The display will now show a steady
NO indication. Press the UP arrow key to change to a ashing YES dis­play. Press ENTER once to access the 4 mA ne adjustment.

Figure 3: Typical Ammeter Connection

4 mA ADJUSTMENT – While monitoring the ammeter, adjust the 4 mA
value to obtain a 4 mA reading. The UP arrow key increments the value and
the RIGHT arrow key decrements the value. When a steady 4 mA reading
is obtained on the ammeter, press the ENTER key to lock in this value and
move to the 20 mA adjustment.

20 mA ADJUSTMENT – The 20 mA adjustment is performed using the
same procedure as the 4 mA adjustment. While monitoring the ammeter,
adjust the 20 mA value to obtain a 20 mA reading. The UP arrow key incre­ments the value and the RIGHT arrow key decrements the value. When a
steady 20 mA reading is obtained on the ammeter, press the ENTER key to
lock in this value and move to the next parameter.

12

4-20 mA TEST – The monitor contains a diagnostic routine that allows the
simulation of mA values between 4 and 20 to check output tracking. At
the 4-20TEST prompt, the arrow keys change the simulated mA output in
increments of 1 mA. The ammeter should track the simulated mA output.
If a 4-20 mA test is not necessary, press the ENTER key once to move to the
next parameter.

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.

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.

13

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.

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.

ADDITIONAL INPUT OPTIONS

+10 - 30 VDC

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 4.

ADDITIONAL SCALING PARAMETERS

This information is supplied as a general introduction to the basic concepts
used to scale rate displays. The applicability of the information is depen­dent on the type and capabilities of the specic display/monitor used.

Flow meters producing an electronic signal are normally supplied in one of
two output formats. The pulse format generates some form of alternating
signal that can be “raw”, that is no amplication or wave shaping can be
done prior to transmission to the readout. The output pulse rate is related
proportionally to ow rate. Pulses can also be modied to produce higher
output amplitudes or specic wave shapes.

The other output format is an analog signal. This is a continuous, variable
voltage or current signal that is normally scaled to the dynamic range of the
meter. Typical analog signals are 0-5 Vdc, 0-10 Vdc, and 4-20 mA. The analog
signals may or may not be derived from a raw pulse signal produced by the
ow meter.

Scaling for any of these input signals always requires at least two scaling
points for a linear process - zero or minimum ow point and the maximum
ow point. Additionally, each scaling point has two components, the actual
input signal value and the desired display value at that input signal for that
scaling point.

For example, a pulse output ow meter has a ow of 50 GPM at a pulse
rate of 100 Hz. The actual input signal is the 100 Hz gure, but allowing the
display to read “100” would be meaningless to the operator. The solution
to this problem is to “scale” the display to “read” 50 (GPM) when the input
is 100 Hz.

PULSE OUTPUT SIGNALS FOR LINEAR PROCESSES
WHERE LINEARIZATION IS NOT NECESSARY

Pulse output signals are related to ow rate by a constant, usually referred
to as the “K-factor”. The K-factor is reported as the number of accumulated
pulses that represents a particular volume such as gallon or liter. K-factors
are indicated in pulses per unit volume or counts per unit volume. An ex­ample of a K-factor, normally supplied by the manufacturer, might be 2000
counts per gallon. The K-factor is correlated to ow through a simple math­ematical relationship:

Frequency = K-factor × Volume per unit of time ÷ 60

20

Using the previous example of 2000 counts per gallon and further assum­ing this meter has a maximum ow rate of 25 GPM, the formula can be
arranged to calculate the input frequency required for a scaling point as
follows:

Frequency = 2000 × 1 (gal) ÷ 60 = 33.333 Hz at 1 GPM

Given that the meter has a maximum ow rate of 25 GPM, the maximum
frequency would then be:

Frequency = 2000 × 25 (gal) ÷ 60 = 833.333 Hz at 25 GPM

A programmable display requires at least two points. The rst point is the
zero or minimum ow and the second is normally the maximum ow rate.
For the imaginary ow meter used in the example above, the scaling would
be as follows:

Input Value for Scaling Point 1 = 0
Display Value for Scaling Point 1 = 0
Input Value for Scaling Point 2 = 833.33
Display Value for Scaling Point 2 = 25

21

PULSE OUTPUT SIGNALS FOR NONLINEAR PROCESSES
APPLICATIONS THAT CAN BENEFIT FROM LINEARIZATION

Few ow meters actually behave in a linear way. There is always some un­certainty about the “exact” ow at a given reported input value. For many
common ow measurement applications, the assumption of linear ow
is adequate for the process being measured. When higher accuracy is re­quired, a technique called “Linearization” is often employed.

When the ow meter is being calibrated, multiple data points are obtained
for the particular meter being tested. A typical ve point calibration run is
displayed below.

If this meter produced an actual linear output, the K-factor calculation

point. Inspection of the UUT K in the example provided shows that this is
not the case and indicates that this meter is not a perfectly linear device.

Many programmable displays allow for linearization and can provide a bet­ter match of the displayed ow values with the actual ow values by in­corporating more measurement points. In the example, the unit would be
programmed for six points, the ve data points and a zero point, and use
pairs of input values to accomplish the linearization.

• Check power supply voltage. Should be between 10 and
30 Vdc.

• 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.
