INTRODUCTION
The B2800 Flow Monitor is a state-of-the-art, microprocessor
based flow monitor, designed to provide the user with exceptional
flexibility at a very affordable price. Though designed for use
with Blancett Flow Meters, this display can be used with almost
any flow meter producing a low amplitude AC output or contact
closure signal(s).
This flow monitor is capable of accepting a low-level frequency
input for calculating flow rate and total. These calculations can
then be displayed in the desired units of measurement. All B2800
flow monitors come pre-calibrated, from the factory, if ordered
with a Blancett Flow Meter. If required, however, it can easily be
re-configured in the field. The monitor’s large 8 digit by .75” nu-
meric liquid crystal display makes extended range viewing practi-
cal. The second 8 digit by .38” alphanumeric display provides for
selectable units viewing in run mode and prompts for variables in
programming mode. Finally, the user can choose between dis-
playing 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 pro-
gram mode display screen enunciators confirming the state of the
monitor. A quick glance at the lower left hand corner of the LCD
screen will confirm operating status. Normal operation will be in
the run mode. To access the programming mode, press the
MENU button until the first 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.
ADVANCED PROGRAMMING MODE
Keys:
MENU – Switch between RUN & PROGRAMMING modes
UP Arrow – Scrolls through programming sub-menus in for-
ward 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 infor-
mation and in the reset process
If your monitor was ordered with a Blancett flow meter, the two
components ship from the factory, calibrated as a set. If the moni-
tor 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 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. (See “General
Notes on Scaling” at the end of this manual). K-factor informa-

7
tion, when supplied, can usually be found on the neck of the flow
meter or stamped on the body. The K-factor represents the num-
ber of pulses per unit of volume. The K-factor will be needed to
program the monitor readout.
ENTER PROGRAMMING MODE – Change to program-
ming mode by pressing the MENU button once. The mode
indicator will change from RUN to PROGRAM.
Note: If any input value exceeds the meters capabilities for that
particular parameter, the LIMIT indicator will begin to flash
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 flash. Using the arrow keys, scroll through the
size choices until you find the bore size of your meter. Press
ENTER once to save the meter size choice.
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
effect. 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 dis-
play mode and press ENTER to save the choice.
SELECT THE RATE UNITS OF MEASURE – The moni-
tor allows the choice of many common rate units. (See the
specifications 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 flow 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
Note: The meter connection size and the bore size are different.
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 could report incorrect flows and totals.

the current selection is correct, press the ENTER key to ad-
vance to the next parameter. To change to an alternate time
interval, use the arrow keys to scroll to the desired time inter-
val and press ENTER to save the choice.
SELECT THE TOTAL UNITS OF MEASURE – If a flow
amount is desirable, the units for the total must first be cho-
sen. The monitor allows the choice of many common totaliza-
tion units. (See the specifications 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.
SELECT THE TOTAL’S DISPLAY MULTIPLIER – The
monitor has a very versatile display that has the ability to ac-
cumulate the flow 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 gal-
lons the total display would read 3, etc. This feature elimi-
nates having to look at a total, counting the digits and men-
tally 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
Note: If flow rate is the only measurement of interest, skip to
KFAC UNT to complete the programming process.
Note: This unit of measure does not have to reflect the rate unit
you have previously chosen. (Example: Rate Units = Gallons,
Total Units = Barrels).

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 de-
sired multiplier unit and press ENTER to save the choice.
Multiplier Choices – 0.01, 0.1, 1, 10, 100, 1000, 10000,
100000, and 1000000 Units
ENTER THE METER’S K-FACTOR UNIT – At the
KFAC UNT prompt, press the ENTER key once. The display
now shows the current K-factor unit. If the current selection is
correct, press the ENTER key to advance to the next parame-
ter. For meters calibrated in gallons use PUL/GAL. For me-
ters calibrated in cubic meters use PUL/M3 (pulses per cubic
meter), etc. To change to an alternate K-factor unit, use the
arrow keys to scroll to the desired K-factor unit and press the
ENTER key to save your choice.
ENTER THE METER’S K-FACTOR – (Note: The K-
factor supplied with your meter or calculated from cali-
bration data will be needed to complete this step.)
At the K FACTOR prompt, press the ENTER key once. The
most significant digit in the K-factor will begin to flash. Us-
ing the UP arrow key, increment the display digit until it
matches the meter’s K-factor digit. If the current selection is
correct, press the RIGHT arrow key to advance to the next
digit. Repeat this process unit all K-factor digits have been
entered. Press ENTER once to save the K-factor.
SCALE FACTOR – At the SCALE F prompt, press the EN-
TER key once. The current Scale Factor will begin to flash. If
the current selection is correct, press the ENTER key to ad-
Note: Unless otherwise specified, turbine flow meters are
supplied with K-factors measured in pulses per gallon
(PUL/GAL).

11
vance 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 flow rates. Rather than changing all pa-
rameters individually, the scale factor can be used to compen-
sate for the 3% offset. 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 EN-
TER 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 Op-
erating 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
flash. If the current selection is correct, press the ENTER key
to advance to the next parameter. The Damping Factor is in-
creased to enhance the stability of the flow readings. Damping
values are decreased to allow the flow meter to react faster to
changing values of flow. This parameter can take on any
value between 0 and 99 with 0 being the default.
TOTALIZER PULSE OUTPUT – The pulse output pa-
rameter can be either enabled or disabled. When enabled this
output generates 20mS duration pulse for every time the least
significant 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 maxi-
mum 30 VDC.
FLOW 4MA SETTING – When the loop powered option is
ordered, the flow rate that corresponds to 4mA must be set. If
the current selection is correct, press the RIGHT arrow key
once to advance to the next parameter. If adjustment is re-
quired, press the ENTER key once at the FLOW 4MA

12
prompt. The most significant digit will begin to flash. 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 4mA flow rate has been entered, press ENTER
once to store this value and move to the next parameter.
FLOW 20mA SETTING – Follow the same programming
procedure as the FLOW 4MA except for the flow rate setting.
In this case, the maximum rate of flow for the meter should be
used.
4-20mA CALIBRATION – When ordered with a 4-20mA
output, this menu item allows the fine adjustment of the 4-
20mA output. The 4mA setting is typically between 35 and
50. To set the 4mA value, connect an ammeter in series with
the loop power supply. At the 4-20CAL prompt, press EN-
TER once. This display will now show a steady NO indica-
tion. Press the UP arrow key to change to a flashing YES dis-
play. Press ENTER once to access the 4mA fine adjustment.

13
4mA ADJUSTMENT – While monitoring the ammeter, ad-
just the 4mA value to obtain a 4mA reading. The UP arrow
key increments the value and the RIGHT arrow key decre-
ments the value. When a steady 4mA reading is obtained on
the ammeter, press the ENTER key to lock in this value and
move to the 20mA adjustment.
20mA ADJUSTMENT – The 20mA adjustment is performed
using the same procedure as the 4mA adjustment.
While monitoring the ammeter, adjust the 20mA value to ob-
tain a 20mA reading. The UP arrow key increments the value
and the RIGHT arrow key decrements the value. When a
steady 20mA reading is obtained on the ammeter, press the
ENTER key to lock in this value and move to the next pa-
rameter.
4-20mA 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 increments of 1mA.
The ammeter should track the simulated mA output. If a 4-
20mA test is not necessary, press ENTER once to move to the
next parameter.
LINEARIZATION – Enhanced accuracy can be obtained by
linearization of the display. The linearization routine will ac-
cept a maximum of ten points. Linearization requires addi-
tional calibration data from the meter to be used with the
monitor. Typically, calibration information can be obtained in
three, five, and ten points from the flow meter’s manufacturer.
If linearization is not needed, pressing the RIGHT arrow key
will take you to the next parameter. (See “General Notes on
Scaling” for more information).
Number of Points – At the LINEAR prompt, press EN-
TER 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

14
RIGHT arrow moves the cursor between digits. When the
number of points has been input, press the ENTER key
once to move to the first linear segment.
Press the ENTER key once and the first linear point’s fre-
quency input will begin to flash (FREQ 1). Enter the fre-
quency for the first linear point using the arrow keys.
When the frequency value input is completed, press EN-
TER once again to change to the coefficient value for the
first linear point.
The coefficient is the value applied to the nominal K-
factor to correct it to the exact K-factor for that point. The
coefficient is calculated by dividing the actual K-factor for
that point by the average K-factor for the flow meter.
Coefficient = Actual K-factor ÷ Average K-factor
At the COEFF prompt, enter the coefficient that corre-
sponds to the frequency value previously entered. Press
ENTER once to move to the next scaling point.
Continue entering pairs of frequency and coefficient
points until all data has been entered. Press the MENU
key twice at the NUM PTS prompts to exit to the LIN-
EAR 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 first digit of the
password value will begin to flash. Using the arrow keys as
previously described, enter the password value. Pressing EN-
TER once will store the password and take you back to the
RST PSWD screen.
Note: This password will allow users to reset totals.

15
RST PSWD – Reset Password protection prevents unauthor-
ized users from manually resetting the flow monitor’s accu-
mulated totals. Initially, the password is set to all zeros. To
change the password, press ENTER once at the password
prompt. The first digit of the password value will begin to
flash. Using the arrow keys as previously described, enter the
password value. Pressing ENTER once will store the pass-
word and take you back to the METER size screen, pressing
MENU exits the programming mode. The B2800 Flow Moni-
tor is now ready for use with its companion meter. Note: en-
tering 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
modification.
RESET TOTAL – To reset the monitor total display, in run
mode press the MENU and ENTER simultaneously until TO-
TAL RST starts to flash. The TOTAL RST will stop flashing
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 flash memory. This procedure may be desir-
able prior to changing the settings or replacing the battery.
Press and hold the ENTER key for 2 seconds. The display
will respond with a flashing 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 flash memory. The frequency of saves depends
on the power supply option chosen
Battery Powered: Once per hour and just before a low
battery condition turns the unit off.
Loop Powered: Once every ten minutes.

16
Battery Replacement – Battery powered monitors use a sin-
gle 1.5V, “D” size, alkaline battery. When replacement is nec-
essary, use a clean fresh battery to insure continued trouble
free operation. It is recommended that the total be saved to
memory before the battery is removed. (See “Store Total” in
the programming section of this manual.)
Unscrew the two captive screws on the front panel to gain ac-
cess to the battery. Replace the battery being sure to observe
the proper polarity, and then re-fasten the front panel.
ADDITIONAL INPUT OPTIONS
The B2800 Flow Monitor is capable of receiving Magnetic Pick-
up Input or a Contact Closure Input. Since most Blancett Flow
Meters utilize a magnetic pick-up, the monitor is shipped config-
ured 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.
