Enter the KFT in the Global Programming section. The K-factor is the number manufacturer provides as
the average K-factor for the transmitter. If this is in imp/Gal, set the totalizer in, say cc’s , by converting
the K-factor to imp/cc. 10000 is a constant.
For example, a flow meter has a K-factor of 106666.0 imp/Gal and the display should show
gallons/minute:
10000
10666.0
Enter 9376 as the KFT and move the DP to 0.937. (See note below).
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. For example, for 60.675, enter 60.6; for 2.34543, enter 2.345
The largest number you can enter as a KFT is 65000. Refer to KFR note above.
3. KFR for B
The same as KFR for A.
4. KFT for B
The same as KFT for A.
5. Units for Rate.
This variable displays the Engineering Units required for the flow rate display. It is strictly a display and
does not perform the actual conversion of raw counted impulses; the KFR handles those calculations.
Enter the two-digit number for the desired Units for Rate:
00 - cc/min 06 - gram/sec
01 - liter/min 07 - lb/min
02 - gallon/min 08 - Kg/min
03 - ounce/min 09 - Kg/sec
04 - RPM 10 - lb/sec
05 - gram/min 11 - lb/Hr
12 - Hz (impulses/sec)
KFT = = .9376 Gal
