Radiant Fuel Gauge For Resistive Or Float Based Fuel

The Radiant RFGA-022R-GEN2 is a GEN-2 fuel gauge for aircraft installations using passive resistive fuel senders, commonly described as float-type senders. It supports display of fuel level for one or two tanks on a compact, sunlight-readable colour screen.

The display combines an analogue-style fuel dial, large digital fuel percentage, fuel quantity and recent fuel-level trend information, helping provide a clear view of current sender readings and their recent behaviour. Fuel quantity can be configured in litres, US gallons or Imperial gallons.

• Manufacturer part number: RFGA-022R-GEN2
• For passive resistive fuel senders connected to ground
• Single- or dual-tank display configuration
• User calibration with 2, 3 or 5 points per tank
• Supports normal or reverse-acting resistive sender curves when correctly calibrated
• Displays sender resistance in real time and can indicate open- or short-circuit sender conditions
• Sunlight-readable, high-contrast colour display with adjustable brightness
