1.2 SYSTEM COMPONENTS
The system consists of three (3) basic units: the fuel flow
transducer, the navigation receiver (Loran-C or GPS) and the panel
mounted unit.
1.2.1 FUEL FLOW TRANSDUCER
The fuel flow transducer mounted in the fuel line measures
the flow of fuel and generates electrical pulses directly
proportional to the fuel flow. The transducer is fail-safe
designed, and stopped rotor will not interrupt fuel flow to
the engine.
1.2.2 LORAN-C OR GPS RECEIVER
The Loran-C or GPS receiver provides ground speed,
distance, and estimated time en route through the serial port.
1.2.3 PANEL MOUNTED UNIT
All system electronics, function controls and digital displays
are contained in a single instrument that mounts in a
standard 2¼” hole. This unit requires no periodic
maintenance, adjustment, or calibration once it is properly
installed.
The Display: The fuel flow is always displayed on the left side of
the display window. All other functions, with the priority for the
rotary switch functions, are displayed on the right side of the
display window.
System Memory: The system includes a non-volatile memory that
retains fuel remaining and fuel used information when the power to
the unit is shut down.
