The G3X default K-Factor for the 201B-6 is 29,500 pulses/gallon. Some Floscan fuel flow sensors come
with a tag that lists the K-factor number measured during unit calibration (see Figure 21-19).
NOTE
If the Floscan tag shown in Figure 21-19 is lost, the serial number of the Floscan sensor
can be supplied to Floscan to obtain the calibrated K-factor value.
Figure 21-19 Example Floscan Fuel Flow Sensor
The tag shown in Figure 21-19 lists a K-Factor of 16-2890. The first two digits (16) represent Gallons Per
Hour, while the last four digits (2890) represent the number of electrical pulses (divided by 10) output by
the sensor per gallon of fuel flow. The numbers on the tag are used in determining the K-Factor to be
entered as part of the Fuel Flow Calibration described in Secti
on 34.4.19.4 (for GDU 37X) and
Section 30.4.32.13
(for GDU 4XX). To find this number, a zero should be added to the four digit number
on the tag. In the example above after adding the zero to 2890, the resulting K-Factor to be entered on the
Fuel Flow Calibration page would be 28900.
