Fuel Flow Sensor
Fly Henry Precision Turbine Fuel Flow Transducers
Engineered specifically for Paramotors (PPG), Microlights, Trikes, and Ultralight (ULL) aircraft, these in-line turbine flow meters provide accurate, real-time fuel consumption telemetry directly to the Fly Henry Fly Meter. Available in two dedicated flow regimes—a sensitive 0.5 – 25 Litres/Hour model for compact single-cylinder paramotors, and a high-flow 0.03 – 2 Litres/Minute (1.8 – 120 L/h) model for larger multi-cylinder or high-demand engines.
Choosing Your Flow Range
Select the model matched to your engine displacement and maximum full-power fuel demand:
| Model Option | Calibrated Measuring Span | Recommended Engine Applications |
|---|---|---|
| 0.5 – 25 Litres / Hour | 0.5 to 25.0 L/h • Ultra-sensitive at low idle & cruise burn | Single-cylinder 2-stroke paramotors up to 250cc (e.g. Vittorazi Atom 80 / Moster 185, EOS 100/150, Top 80, Minari) |
| 0.03 – 2.0 Litres / Minute | Equivalent to 1.8 to 120 L/h • Low restriction for high fuel demand | High-output 2-strokes, twin-cylinder engines, trikes, and light 4-strokes (e.g. Polini Thor 250/303, Rotax 447/503/582, Simonini, HKS) |
0.5 – 25 L/h (Paramotor Focus)
Specifically tuned for the low fuel consumption profiles of modern paramotors. Because standard flow meters struggle to register accurate pulses at tiny burn rates (e.g., 2.5 to 4.5 L/h during level cruise), this high-sensitivity turbine ensures exceptional accuracy down to half a litre per hour.
0.03 – 2.0 L/min (High Flow Focus)
Engineered for higher horsepower powerplants requiring up to 120 litres per hour under wide-open throttle (WOT). Features an enlarged flow path to eliminate fuel line pressure drops, ensuring your engine receives unobstructed fuel volume during full-power takeoff and extended climbs.
Cockpit Safety & Management Benefits
Unlocking the full power computer functions of your Fly Meter:
Real-Time Burn & Endurance
Continuously measures instant fuel flow (L/h or GPH), average consumption, and total burnt volume. Combines with your known tank capacity to calculate exact remaining flight airtime down to the minute.
Fuel Line Leakage Detection
Compatible with the 2024 Fly Meter's high-flow alert function. If a fuel pipe splits or a carburettor float valve sticks open, the meter detects the abnormal flow surge and flashes a warning on screen immediately.
Low Pressure-Drop Turbine
The internal Pelton micro-wheel creates minimal hydraulic drag, making it completely safe for suction-fed diaphragm carburettors and low-head gravity fuel systems without inducing vapour lock.
Ethanol & Oil Resistant
Constructed from chemically inert fuelsafe polymers and high-grade stainless components, fully certified for prolonged immersion in unleaded Mogas (E5/E10), 100LL AvGas, and modern 2-stroke oils.
