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-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

programming mode. Finally, the user can choose between displaying

rate, total, or alternating between both rate and total.

Specications 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

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 specied, 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.

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 max. 30 VDC.

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.

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 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 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 Simplied 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.
