23.3.11.1 K-Factor for Floscan 201B-6
The Floscan 201B-6 (201-030-000) fuel flow sensor ranges from 28,000 to 31,000 pulses/gallon.
The G3X default K factor for the 201B-6 is set to 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 23-18).
NOTE
If the Floscan tag shown in Figure 23-18 is lost, the serial number of the Floscan sensor
can be supplied to Floscan to obtain the calibrated K factor value.
Figure 23-18 Example Floscan Fuel Flow Sensor
The tag shown in Figure 23-18 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
(for GDU 37X) and
(for GDU 4XX). To determine 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.
23.3.11.2 K-Factor for Electronics International FT-60 (Red Cube)
The G3X default K factor for the FT-60 is set to 68,000 pulses/gallon. No sensor specific calibration is
required for the FT-60 but variations in the installation can affect the K factor. Reference Electronics
International document #1030033 and
(for GDU 37X) and
(for
GDU 4XX) for additional information.
