K -factor
Enter this KFR number in the Global Programming section. The K-factor is the number the manufacturer
provides as the average K-factor for the transmitter.
For example, a flow meter has the K-factor 2053.7 imp/GAL and the display should show
Gallons/minute.
6000
2053.7
Enter 2921 as the KFR; use the DP (decimal point) key to move the DP to the number 2.921.
Calculator mathematics produce insignificant decimal numbers for our purposes. These produce a
misleading level of precision in the display. The factory recommends using a maximum of four digits
regardless of the decimal point position.
Example:

for 60.675, enter 60.67

for 2.3456, enter 2.346
The largest number you can enter as a KFR is 65000, ignoring the decimal point position. A message
alerts you if the number you enter is too large.
2. FT for A (Default 10000)
In order to make the EMO-500 display the correct Totalized Value in Engineering Units, again the most
important thing to know is the K-factor of the flow meter. The K-factor is the relationship between the
amount of the impulses and the engineering units.
To calculate the KFT, apply the following formula:
10000

100 is the constant for seconds
6000 is the constant for minutes
360000 is the constant for hours
