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.

BASIC 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 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 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 PROGRAMMING MODE – Change to program-

ming 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

choices and advance to the K-factor units selection.

ENTER THE METER’S K-FACTOR UNIT – Directly af-

ter 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.

ENTER THE METER’S K-FACTOR – To change the K-

FACTOR value, use the RIGHT arrow key and select the po-

sition of the number that you wish to change. Using the UP

arrow key, increment the display digit until it matches the me-

ter’s K-factor digit. Repeat this process until all K-factor dig-

its 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 five 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 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.

Note: The meter connection size and the bore size are dif-

ferent. 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

flows and totals.

Note: Unless otherwise specified, Blancett turbine flow

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.

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 alter-

nate 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 be-

ing supplied to the frequency input terminals. This is very

useful when troubleshooting flow problems.

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. The amplitude of

the pulse is dependent on the voltage level of the supply con-

nected to the pulse output and is limited to a max. 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 de-

scribed, enter the password value. Pressing ENTER once will

Note: The total unit’s output multiplier cannot be modi-

fied in the Simplified program level. This option is re-

served in the Advanced program level.

store the password and take you back to the RST PSWD

screen.

RST PSWD – The reset password screen allows the operator

to enter any 4 digit code for the manual reset totals function.

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 reset procedure.

STORE TOTAL – The current total can be manually stored

in the monitor’s flash memory. This procedure may be desir-

able prior to 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.

BATTERY REPLACEMENT – Battery powered monitors

use a single 1.5V, “D” size, alkaline battery. When replace-

ment is necessary, use a clean fresh battery to insure contin-

ued trouble free operation. It is recommended that the total be

saved to memory before the battery is removed. (See STORE

reset totals.

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 (small signal sine wave) or a Contact Closure input

(pulse). Since most Blancett Turbine Flow Meters utilize a mag-

netic pick-up, the B2800 flow monitor is shipped configured for

magnetic pick-up input. To change to a contact closure input, re-

move JP2 from the top two pins and jumper them to the bottom

two pins. See Figure 2.
