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.
