Flowtrecs Wave DIESEL

Multifunctional Fuel Computer WAVE 4.3" (Single Diesel)

Flowtrecs WAVE 4.3 Single Diesel is a comprehensive fuel computer designed to display the most important parameters for marine vessels equipped with a single diesel engine (with fuel return line). It is the perfect solution for motorboats and yachts requiring precise fuel management in harsh conditions.

The device displays vital parameters including: current fuel consumption, fuel economy, RPM, speed, battery voltage, and statistical data. Unlike standard versions, this model is equipped with two sensors to perform differential measurement (Feed & Return), ensuring accurate readings for diesel engines.

The system is equipped with a high-brightness 4.3" capacitive touch screen ensuring excellent readability in sunlight. The housing is fully waterproof (IP68), allowing it to work in open cockpits and virtually any weather condition. It uses reliable and durable aluminum alloy sensors with sapphire bearings.

Main features:

1. Fuel consumption (l/h)
2. Total fuel consumption
3. Fuel Economy indicator (km/l or nm/l)
4. Fuel in tank (remaining)
5. Range
6. Speed (GPS)
7. Voltage monitoring
8. Clock and Distance
9. Screen brightness control
10. Engine hour counter (MTH)
11. Single Diesel Operation (Differential measurement Feed/Return)
12. MOB - Man Overboard (saves current position)
13. Anchor alarm
14. Multilanguage screens (DE, ENG)
15. Units selection: km/h, knots, l/h, gal/h (UK/US)
16. Settings lock (password secured)

Package includes:

• 1 x 4.3″ CTP TFT colour touch panel (IP68 Waterproof)
• 2 x FS-40 flow sensors (1 x Feed & 1 x Return)
• 1 x Sensor-Converter cable harness (5 m)
• Operating instruction
• Cable ties

IMPORTANT NOTICE - SENSOR SELECTION FOR DIESEL:

For Diesel engines equipped with a fuel return line, selecting the correct sensors requires knowing your fuel pump's capacity, not just the engine's fuel consumption.

In diesel systems, the fuel pump circulates much more fuel than the engine actually consumes (the excess returns to the tank). Therefore, the flow sensors must handle the full flow rate of the feed pump.

Example: if an engine consumes 50 l/h while its feed line carries 100 l/h, the feed sensor must accommodate 100 l/h, not just the 50 l/h consumed. XL may be suitable. We confirm the final selection after checking the minimum and maximum flow in both the feed and return lines and the installation requirements, including allowable pressure loss.

Installation Notes:

• RPM readings: An additional Hall sensor may be required if the engine does not provide a suitable electronic RPM signal.
• Pulsation: Depending on the condition of your engine's feeding pump, additional components like one-way valves or pulsation dampers may be necessary.

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 and pump capacity in the order comments, and we will verify the best sensor fit for you.
