Section III - SYSTEMS DESCRIPTION
Fuel Flow Indicating
Each engine fuel flow indicating system consists of:
• Fuel Flow Transmitter
• Data Concentrator Unit (DCU)
• Flow Rate Indication
The transmitter is a turbine-driven motor that rotates and generates an AC electrical signal as fuel flows
past it. The AC voltage passes through a converter where DC voltage is supplied to the Data
Concentrator Unit (DCU) which supplies the data to the MFD for the fuel flow indications.
The fuel flow indicating system uses 28 VDC power from the PS1 and PS2 busbars. The left system
receives power from the PS1 busbar, and the right system receives power from the PS2 busbar.
Additional Fuel System Components
Additional fuel system components are the associated fuel lines and plenum drain valves. No fuel is
allowed to drain from the plenum in normal operations, but any fuel accumulation during a false start is
drained.
