Flowtrecs APP for Android (twin engines)

Wireless Fuel Computer for Android - Twin Petrol Engine

This version is designed for petrol engines without a fuel return line. Engines with a return line require a suitable differential-measurement version.

Flowtrecs APP Twin Petrol is a modern, wireless fuel consumption measuring system that turns your Android device (phone or tablet) into a professional board computer. It is designed specifically for motorboats and yachts equipped with two petrol (gasoline) engines.

The system consists of two flow sensors (one for each engine) and a wireless Bluetooth transmitter unit. The data is displayed directly on your mobile device via the free Flowtrecs App (available on Google Play).

This solution allows you to save dashboard space and money by utilizing the high-quality screen and GPS of your own smartphone or tablet. The installation is extremely simple thanks to the wireless connection.

Main features:

1. Independent fuel consumption for both engines (l/h)
2. Total fuel consumption (combined)
3. Fuel Economy indicator (km/l or l/km)
4. Fuel in tank (remaining)
5. Range
6. Speed (via GPS)
7. Battery Voltage
8. Engine hour counter (MTH) for both engines
9. Twin Engine Operation
10. MOB (Man Overboard) function
11. Units selection: km/h, knots, l/h, gal/h (UK/US)
12. Engine speed (RPM) — requires a suitable engine-speed signal

Package includes:

• 1 x Wireless Bluetooth Interface (Twin Channel)
• 2 x FS-40 Flow Sensors (Selected size)
• User Manual
• Cable ties
• Note: Tablet/Smartphone is NOT included.

IMPORTANT - SENSOR & VERSION SELECTION:

1. Petrol Engines: This kit includes 2 sensors and is designed for boats with two petrol engines (outboard or inboard).

2. Diesel Engines: If you have Diesel engines with a fuel return line, this version will NOT work correctly. For Diesel engines, please choose the Flowtrecs Diesel version.

3. Sensor Size: Please choose the sensor capacity based on your engine's maximum fuel flow.

Available Flow Sensor Versions (per sensor):

• S for engines 20 - 60 HP (0.5 - 20 l/h) (1.2 mm nozzle diameter)
• M for engines 60 - 130 HP (1 - 40 l/h) (2 mm nozzle diameter)
• L for engines 130 - 250 HP (1.5 - 90 l/h) (3 mm nozzle diameter)
• XL for engines 250 - 300 HP (2 - 120 l/h) (4 mm nozzle diameter)
• XXL for engines 300 - 350 HP (3 - 180 l/h) (4.5 mm nozzle diameter)
• 3XL for engines 350 HP and more (5 - 300 l/h) (6 mm nozzle diameter)

Live fuel-consumption and fuel-economy readings help you adjust speed, trim and load distribution. Choosing efficient settings can reduce fuel use and running costs; savings depend on the boat, conditions and the skipper’s adjustments.

After purchasing, please specify your engine model in the order comments, and we will verify the best sensor fit for you.
