Introduction
The BK2800 Flow Monitor is a state-of-the-art, microprocessor
based ow monitor, designed to provide the user with exceptional
exibility at a very affordable price. Though designed for use
with Kimray Flow 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 B2800
ow monitors come pre-calibrated, from the factory, if ordered
with a Kimray Flow Meter. If required, however, it can easily be
re-congured 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
programming mode. Finally, the user can choose between displaying
rate, total, or alternating between both rate and total.

Specications 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 conrming the state of the monitor. A quick glance at the
lower left hand corner of the LCD screen will conrm
operating status. Normal operation will be in the RUN mode. To access the
programming 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 unau-
thorized access or changing the meter’s setup parameters.
Programming Mode
Keys:
MENU – Switches to Programming 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 a Kimray 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 the monitor.
Kfactor 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 Programming Mode
Change to programming 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 me-
ter size choices and advance to the K-factor units selection.
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 will report incorrect ows and totals.
Note
Unless otherwise specied, Kimray 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 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 Kfactor unit and advance to the
next parameter.
Enter the Meter’s K-Factor
To change the KFACTOR 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 K-factor and advance to the
RATE/TOTAL Units selection.
Select the Rate/Total Units of Measure
The monitor allows the choice of ve common rate/total units. The
monitor shows the rate/total unit that the display is currently set for.
If the current selection is current, press the ENTER key once to ad-
vance 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.

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 signicant 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 max. 30 VDC.

Battery Replacement
Battery powered monitors use a single 1.5V, “D” size, alkaline battery.
When replacement is necessary, 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 access to the battery. Replace the
battery being sure to observe the proper polarity, and then re-fasten
the front panel.
Automatic Store Total
The monitor is equipped with a store total feature that works automati-
cally, saving the current total to ash 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.
Additional Input Options
The BK2800 Flow Monitor is capable of receiving Magnetic Pickup
input (small signal sine wave) or a Contact Closure input
(pulse). Since most Kimray Turbine Flow Meters utilize a magnetic
pick-up, the BK2800 ow monitor is shipped congured 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 2.

Additional Scaling Parameters
Note
The programming instructions below are only
available when purchasing a loop powered unit. Battery pow-
ered units will not see these programming choices.
BK2800 Simplied 4-20mA Programming Instructions
FLOW 4mA SETTING – When the loop powered option is
ordered, the ow rate that corresponds to 4mA must be set.
Zero is default ow rate for this setting. If the current selection
is correct, press the ENTER key once to advance to the
next parameter. If adjustment is required use the RIGHT arrow
key to select the position of the number you wish to
change, then, use the UP arrow key to increment the number.
Once you have completed this step, press the ENTER key to
advance to the next parameter.
FLOW 20mA SETTING – The ow rate that corresponds to
20mA must be set next. The turbine meter’s maximum ow
rate is the default value. If the current selection is correct,
press the ENTER key once to advance to the next parameter.
If adjustment is required use the RIGHT arrow key to select
the position of the number you wish to change, then, use the
UP arrow key to increment the number. Once you have completed
this step, press the ENTER key to advance to the next
parameter.
4-20mA CALIBRATION – When ordered with a 4-20mA
option this menu item allows the ne 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 4mA OUT prompt, adjust the
4mA value to obtain a 4mA reading on the ammeter. The UP
arrow key increments the value and the RIGHT arrow key
decrements 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. The 20mA adjustment is performed using
the same procedure as the 4mA adjustment. 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 in increments of 1mA. The
ammeter should track the simulated mA output. If a 4- 20mA test in not
necessary, pressing the ENTER key once will escape the testing at any
time.
Note
If your BK2800 ow monitor was ordered with a
Kimray Turbine ow meter, the 4-20mA was programmed
and factory calibrated.
