The Fuel Flow Sensor tracks engine fuel flow, fuel used, trip fuel used and seasonal fuel used - sharing the information with any compatible display unit connected to the NMEA 2000 network. With a speed source in the network, the fuel flow sensor can also calculate fuel economyFuel flow sensor gasoline onlyOne required per engineUp to 3 engines supportedFuel flow, tank fuel used, trip fuel used, seasonal fuel used10' cableSharing the information with any compatible display unit connected to the NMEA 2000 networkWith a speed source in the network, the fuel flow sensor can also calculate fuel economy3/8" fuel line diameterOptimized for 0.6-45 Gallons/hr but can measure outside these valuesIncludes fuel flow sensor, N2K-T and (2) 1" hose clamps0.5 PSI at 20 Gallons/hr; 1 PSI at 40 Gallons/hr added back pressure to the fuel system
