7-2 Calculating the K Factors.
The following steps are the recommended
procedure forcalculating the K Factors. Take
your time and go through the procedure
slowly at first. After several tries you should
be fairly adept at calculating the K Factor for
any given input.
7-2.1 Calculating the K Factor for Digital
Pulse Inputs.
Step 1. Find out what value the pulses repre-
sent. This should be specified
on your device or with its paper
work.
Example #1: 360 Pulses = 1 yard
Example #2: 1 Pulse = 2 gallons
Example #3: 2000 Pulses = 1 m
3
Step 2. The Count K Factor is equal to the
number of pulses per value from
Step 1 (Pulses ÷ Value).
Example #1: Count K Factor = 360
Example #2: Count K Factor = 0.5 (1 pulse ÷
2 gallons)
Example #3: Count K Factor = 2000
TIME CONVERSION CHART
To convert: divide by
sec to min 60.00
sec to hr 3600
min to sec 0.01666667
min to hr 60.00
hr to min 0.01666667
hr to sec 0.0002778
7-2.2 Digital K Factor Formulas
Pulses = Base K Factor
Units Value
Base K Factor . = Count K Factor
Units Conversion Factor
Count K Factor . = Rate K Factor
Time Conversion Factor
Step 3. Enter the Count K Factor. (See
Section 3-3, Menu Item 3).
Step 4. Modify the Count K Factor to reflect
any time conversions for the rate
display to the Rate K Factor. This
is done by dividing the Count K
Factor by the Time Conversion Fac-
tor. If no conversion is necessary
skip this step and let the Rate K
Factor be the same as the Count K
Factor. USE THE TIME CONVER-
SION CHART AS NEEDED.
Example #1: Convert yds per sec to yds per
hour.
Rate K Factor = 360 ÷ 3600 = 0.100
Example #2: Convert gallons per sec to gal-
lons per min.
Rate K Factor = 0.5 ÷ 60 = 0.0083333
Example #3: No conversion necessary.
Rate K Factor = 2000
Step 5. Enter the Rate K Factor.
