FUEL MANAGEMENT GAUGE
The fuel management gauge has the functions as a fuel flow gauge, fuel consumption gauge, fuel
economy gauge, twin engine RPM synchronizer for dual installations, and an optional water separa-
tor warning indicator that detects water in the fuel filter.
The gauge can display by receiving data from the fuel flow sensor and either a NMEA 0183 compat-
ible GPS unit or the digital speedometer.
* Fuel management gauge with speedometer does not have the function as twin engine RPM synchronizer,
water detection warning, and each engine’s fuel measurement.
