Fuel Flow Sensor
The approximate pulses/gallon setting for the FloScan 201B (i.e., cast metal case
legacy Dynon sensor) is 28,000 to 31,000. The approximate pulses/gallon for the
Electronics International FT-60 (i.e., the red cube) is 68,000. You must configure the
fuel flow sensor using this numerical value in the Sensor Setup Menu (SETUP MENU
> HARDWARE CALIBRATION > EMS CALIBRATION > FUEL FLOW CALIBRATION).
More information on this topic is discussed in the Fuel Computer Configuration
section of this chapter.
FloScan 201B sensor only: make note of the numbers on the tag (pulses / gallon)
attached to the fuel flow sensor.
Dynon Avionics supplies the
Electronics International FT-60
(Dynon P/N 100403-003) fuel flow
transducer. Dynon no longer
supplies the FloScan 201B, but
SkyView is compatible with this
sensor.
The SV-EMS-220/221 supports
differential fuel flow sensor
installations in Rotax 912 and 914
installations as illustrated in Figure
40.
Table 36 revisits which SV-EMS-
220/221 pins are compatible with
fuel flow sources.
General Placement Recommendations
 Do not install the Fuel Flow Transducer, hoses and fittings near exhaust system or
turbocharger. Excessive heat can damage fuel system components.
 Do not install 90 degree fittings (elbows) on the input or output of the Fuel Flow
Transducer. Doing so will cause turbulence in the fuel flow which causes inaccurate fuel
flow data.
