Sensors that provide a voltage output can be used without modification, if
calibration characteristics are known.
Sensors that provide a resistance or current output may require replacement
with a supported sensor (e.g. 494-30004-02 or 494-30004-03).
Most sensors that provide a digital output signal can be used without
modification, if calibration characteristics are known.
Many existing installations use Floscan or Electronics International fuel flow
sensors that are directly supported by the G3X system.
Most shunt-type or Hall-effect sensors can be used without modification, if
calibration characteristics are known.
Most sensors that provide a resistance, voltage, or frequency output can be
used without modification. New fuel quantity calibration will be performed
during G3X system installation.
For capacitive fuel quantity measurement, a third-party capacitance-to-
frequency or capacitance-to-voltage converter is required; the G3X system
does not support direct connection to capacitive fuel tank probes.
Most potentiometer-type sensors can be used without modification. New
position calibration will be performed during G3X system installation.
