THE SCALE FACTOR IS CALCULATED USING:
SF (ASCFAC) = Desired Display Decimal DDD
(Number of pulses per “single” unit x CM x SM)

Number of pulses per “single” unit: pulses per unit generated by the process (i.e. #
of pulses per Pound or Kilogram)
CM: Counter Mode (A C
n
t) times factor of the mode 1, 2 or 4. (MVP default 1 (cnt))
SM: Scale Multiplier (ASCALr) selection of 1, 0.1 or 0.01 (MVP sets to default 1)
Notes:
One gallon of water = 8.33 pounds (3.78 kg)
One gallon = 231 cubic inches (3785 cc)
One cubic centimeter (cc) or milliliter (ml) = 1gram of water
Resin Specific Gravity: weight of 1 gallon of resin in pounds

Follow are some examples of show how to calculate the Scale Factor using both metric
and imperial units. There are also work sheets available in chapter 7 of this manual that
will allow for entering the data for any particular application / material.
Number of pulses per stroke – the number of pulses per one stroke generated by the
sensor assembly install on your system. It is best to adjust the sensor assembly so that
it is centered on the pump stroke this will help to stabilize the rate readings.
Resin Weight per volume (cubic inches, cubic centimeter, gallons or liters) – The
weight of one unit of measure you wish to display - or Specific Gravity of the resin.
