Fuel sensor FS-40-12-AL

Flowtrecs Flow Sensor FS-40-12 (Range L - 3XL)

High-capacity turbine flow sensor (FS-40-12) for higher fuel flow rates. The larger flow passage is intended for these applications; correct sizing must take account of the required flow range and allowable pressure loss in the fuel system.

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 L, XL, XXL, and 3XL, used for large outboard motors and powerful inboard engines.

Main features:

1. Model FS-40-12 (High Flow Capacity)
2. Sapphire Bearings – for long life and precision
3. Robust Aluminum housing (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.

• L (1.5 - 90 l/h) – Engines 130 - 250 HP (3 mm nozzle)
• XL (2 - 120 l/h) – Engines 250 - 300 HP (4 mm nozzle)
• XXL (3 - 180 l/h) – Engines 300 - 350 HP (4.5 mm nozzle)
• 3XL (5 - 300 l/h) – Engines 350 HP+ (6 mm nozzle)

Note: For smaller engines (below 130 HP), please choose the Flowtrecs FS-40-10 Sensor (Sizes S, M).

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.
