Electronic flow meter "Flowtrecs" is designed for boats with mechanical drive, processing and showing the data of the motor and boat traffic in a way that allows the user to the most cost-effective management of fuel. As you know, on the fuel consumption of the vessel influence many factors. Some of them such as speed, weight distribution of the bow-stern, setting the trim, propeller selection can be controlled and adjusted by the driver. But how do you know, how to adjust the various settings with no actual measurement data? How do you know that eg. by reducing the speed of 5 km / h, or by picking up the motor you can drive 20 km instead of 15 km on the same amount of fuel? Experienced skippers can partly optimize the movement of the boat, seeing the size of the wave produced during the flow, but this is effective only in relation to setting the trim, while in relation to the other factors unfortunately not. Change of fuel consumption as a function of speed runs non-linearly and do not know how to find the optimum, without objective data. The only effective solution in this case is the measurement of actual fuel consumption and boat speed and calculation of the index giving the economy the number of kilometers, which at the time, at current settings, trim, rotation, ballast, you can sail on one liter of fuel. This is precisely the functionality provided by "Flowtrecs".

“Flowtrecs TS 4.3 ” is recommended for motorboats. It indicates the parameters of engine operations and the boat's movement  in a way which allows the users  to drive at maximum fuel efficiency. Apart from the basic parameters, such as engine's RPM, boat's speed, fuel  consumption in  l/h,  amount  of  fuel, voltage and  motohours  it  indicates  an  essential parameter like  fuel  economy, showing the number of  kilometres one can travel on 1 litre  of fuel.  Equipped  with built-in GPS module and fuel  flow sensor its giving „all in one” possibility for all boats. Aplicable range of engine power is 20-300HP, divided into 3 groups: 20-60HP, 60-130HP, 130-300HP. Touch screen makes it very easy to navigate between  different data screens. This type is available for single or twin engine boats, gas and diesel engines (with or w/o  fuel return hose).
