Fuel sensor FS-40-10-AL

Flowtrecs Flow Sensor FS-4-10 (Range S / M)

High-precision turbine flow sensor (Model FS-4-10) designed for engines with lower fuel consumption (20 - 130 HP). It features a robust aluminum housing and is internally calibrated for maximum precision at lower flow rates.

The device is compatible with all Flowtrecs computers (Mini, INOX, and APP versions). The internal turbine rotates on Sapphire Bearings, ensuring minimal friction, high measurement accuracy, and exceptional durability.

This listing covers versions S and M, typically used for outboard motors and smaller inboard engines.

Main features:

1. Model FS-4-10 (Calibrated for S / M ranges)
2. Sapphire Bearings – for long life and precision
3. Solid Aluminum housing (Durable and Saltwater resistant)
4. Works with Gasoline and Diesel fuel
5. Standard hose connection (clamps included)

AVAILABLE VERSIONS (Select from dropdown):

Please choose the version based on your engine's power and maximum fuel consumption.

• S (0.5 - 20 l/h) – Engines 20 - 60 HP (1.2 mm nozzle)
• M (1 - 40 l/h) – Engines 60 - 130 HP (2 mm nozzle)

Note: For engines larger than 130 HP, please choose the larger Flowtrecs Sensor (Sizes L, XL, XXL).

IMPORTANT NOTE FOR DIESEL ENGINES:

If you are buying this sensor for a Diesel engine with a fuel return line (where excess fuel returns to the tank), remember that measuring consumption requires two sensors (one on feed, one on return) and a Flowtrecs device that supports differential measurement.

If you are unsure which size to choose, please specify your engine model in the order comments.
