7-inch Flowtrecs C7 Ultra Android BT DIESEL

Multifunctional Wireless Fuel Computer – Single Diesel Engine

Flowtrecs C7 Ultra Android BT Diesel is a comprehensive fuel monitoring system designed to display the most important parameters of boats and yachts equipped with a single diesel engine with a fuel return line. It can be used with both inboard and outboard diesel engines.

The system uses two fuel flow sensors: one installed in the fuel supply line and one in the return line. Actual fuel consumption is calculated continuously as the difference between the supply and return flow. The system displays current fuel consumption, total fuel used, fuel economy, remaining fuel, estimated range, engine RPM, GPS speed, battery voltage and statistical data. Additional safety functions, such as MOB (Man Overboard), are also included.

The system is equipped with a bright 7" IPS capacitive touchscreen with 1000 nits brightness. The display has a durable, waterproof housing with an IPX6 protection rating, making it suitable for marine environments and exposed installation locations. The system also includes two durable aluminum alloy flow sensors with internal sapphire bearings. The display runs on Android 12 and features an Octa-Core processor, 4 GB RAM and 64 GB internal storage. Users can install additional applications such as maps, navigation and weather apps. A wireless Bluetooth 5.0 connection between the measurement hub and the display simplifies installation by eliminating long signal cable runs between the engine compartment and the cabin.

IMPORTANT NOTICE – SENSOR SELECTION FOR DIESEL ENGINES:

Sensor capacity: For diesel engines equipped with a fuel return line, the sensors must be selected according to the full fuel pump flow rate, not only according to the engine’s actual fuel consumption.

A diesel fuel pump usually circulates significantly more fuel than the engine consumes. The unused fuel flows back to the tank through the return line. Both sensors must therefore be capable of measuring the full circulating fuel flow.

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.

The specified flow range applies to each sensor separately.

Installation notes:

• RPM readings: An additional Hall sensor may be required if the engine does not provide a suitable electronic RPM signal.
• Fuel pulsation: Depending on the fuel pump and injection system, additional non-return valves or pulsation dampers may be required to stabilize the readings. These components are available separately.

Available flow sensor versions – per sensor:

• S – flow range 0.5–20 l/h, 1.2 mm nozzle diameter
• M – flow range 1–40 l/h, 2 mm nozzle diameter
• L – flow range 1.5–90 l/h, 3 mm nozzle diameter
• XL – flow range 2–120 l/h, 4 mm nozzle diameter
• XXL – flow range 3–180 l/h, 4.5 mm nozzle diameter
• 3XL – flow range 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 the engine manufacturer, model, power, year and fuel pump capacity in the order comments. We will verify the most suitable sensor version for your installation.
