United 6511 Fuel Flow Indicator
This part number designates a panel-mounted electric fuel flow indicator manufactured by Hickok Electrical Instrument Co. (Model 563-221) for Textron Beechcraft. It is a primary engine monitoring instrument factory-installed on high-performance general aviation aircraft.
Description
This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 06/03/2026.
Key Technical Capabilities
- Electrical Signal Processing: Engineered to process continuous frequency or electrical inputs directly from an inline fuel flow transmitter/transducer, translating raw sensor feedback into precise, stable needle deflection.
- Dedicated Space Optimization: Built inside a space-saving 2-inch cylindrical housing rather than a standard 3-inch profile. This compact footprint allows it to be tightly integrated into secondary engine gauge clusters without consuming valuable flight deck space.
- Crucial Mixture Management: Provides clear resolution across a 3 to 30 GPH scale, allowing pilots to accurately monitor fuel burn, calculate cross-country endurance limits, and properly adjust the fuel-air mixture to match performance charts.
- Damped Mechanical Display: Employs an internal movement layout that dampens high-frequency engine harmonics and airframe vibrations, preventing needle jitter or pointer float during high-power climbs or cruise phases.
