Page 3: Introduction
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. -

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. - Page 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 –...
- Page 8 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.

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. Note: If flow rate is the only measurement of interest, skip to KFAC UNT to complete the programming process.

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. - Page 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.

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. -

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. - Page 15 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-...

TROUBLE SHOOTING GUIDE Trouble Remedy • Battery Powered Version: Check battery voltage. Should be 1.5 VDC. Replace if low or bad. • No LCD Display Loop Powered Version: Check for current flow in the loop. Check polarity of the current loop connections for proper orientation. -
Page 22: General Notes On Scaling
GENERAL NOTES ON SCALING This information is supplied as a general introduction to the basic concepts used to scale rate displays. The applicability of the infor- mation is dependent on the type and capabilities of the specific display/monitor used. Flow meters producing an electronic signal are normally supplied in one of two output formats. - Page 23 lar volume such as gallon or liter. K-factors are indicated in pulsed per unit volume or counts per unit volume. An exam- ple of a K-factor, normally supplied by the manufacturer, might be 2000 counts per gallon. The K-factor is correlated to flow through a simple mathematical relationship: Frequency = K-factor x Volume per unit of time ÷...
