Count Scaler
Calculating the Count Scale Factor
The count scale factor is used to convert the incoming count
pulses to the desired unit of measure to be displayed (feet,
gallons, etc.) or to correct for a known amount of error (wheel
wear, viscosity, etc.). This scaler has six digits available with a
fixed decimal point.
Count Scaler Range:
0.0001 to 99.9999
Count Scaler (CS) Formula:
where:
DPF is the decimal point factor corresponding to the desired
decimal point location.

XX.XXXX = 10,000
XXXX.XX =

PPI is the number of pulses per item from the sensor (times 2
if doubled count mode).
Example 1:
A transmitter produces 50 pulses per gallon of
product. Calculate the count scaler required to indicate num
-
ber of gallons per product (XXXXXX).
Example 2:
A turbine meter preamp produces 15.8 pulses
per liter. Calculate the count scaler required to indicate the
number of liters of product that has passed through the meter
(XXXX.XX).
(Select the XXXX.XX position on the totalizer decimal point
menu.)

Programming Count Scale Factor
The first screen in the program mode is used to enter the
count scale factor.
The far right digit will be flashing. Press the
key until
reaching the desired digit value.
Note:
Pressing and holding the
key will cause the
numbers to autoscroll.
Next press the
key to move the flashing digit one
place to the left. Change this digit to the desired value with
the
key.
Repeat this process until all digits are set correctly.
(Setting the count scale factor to 0.00000 will allow
scaling by 100.)
Programming Totalizer Decimal Point
The second screen is used to enter the decimal point
display on the totalizer screen. Press and hold the key
and then press the
key to move from
screen one to screen two.
Press the
key to move the decimal point to the
desired position.
