Flybox Omnia Fuel L-P (57 mm & 80 mm)
The Flybox Omnia Fuel L-P is an integrated fuel management instrument combining precision fuel level indication for up to two tanks with real-time fuel pressure monitoring. Engineered for Ultralight, Light Sport (LSA), and Experimental aircraft, it provides immediate insight into remaining fuel reserves and pump delivery pressure on a sunlight-readable colour graphic display. Available in standard 57 mm (2-1/4″) and 80 mm (3-1/8″) round panel cutouts.
Choosing Your Instrument Size
Select the standard round aviation cutout diameter that best suits your cockpit panel:
Omnia Fuel L-P 57 mm (2-1/4″)
The perfect fit for space-constrained panels, centre pedestals, or secondary consoles. Fits into standard 57 mm instrument cutouts while combining dual tank levels and fluid pressure into one clean display face.
Omnia Fuel L-P 80 mm (3-1/8″)
A direct drop-in replacement for traditional 3-1/8″ mechanical aircraft gauges. Delivers an expanded dial diameter, larger numeric readouts, and wider arc graphics for effortless scanning from both seats.
Operational Capabilities & Fuel Safety
Comprehensive fuel system monitoring in a single dedicated flight instrument:
Dual-Tank Level Oversight
Monitors up to two independent fuel cells (Left/Right wing tanks or Main/Auxiliary). Features individual low-fuel reserve alert setpoints to notify the pilot well before fuel starvation occurs.
Line Pressure Guard
Tracks fuel supply pressure continuously in Bar or PSI. Supports low-pressure carburettor setups as well as high-pressure injection systems, featuring custom low and high alert thresholds.
Non-Linear Tank Calibration
Features an integrated multi-point calibration routine that compensates for tapered, sculpted, or irregular fuel tank profiles, guaranteeing linear and reliable fuel readouts across all volume levels.
Aural & Visual Annunciation
Equipped with an audio line-out that routes voice and tone warnings directly to your cockpit intercom, accompanied by two programmable NPN outputs to trigger external master warning lamps.
