INSTALLATION AND SETUP GUIDE 

Using of additionally installed fuel sensor. 

It is possible to use additionally installed capacitive fuel sensor. As the benefit of this method is high 
precision of measurements, it is around 0.2-1%. As the drawbacks of this method is high costs related to 
the price of fuel sensor and difficult installation. As other drawback is limited possibilities to install 
additional sensors 

–

 in most cases it is possible to install additional sensors only on trucks, tractors and 

construction machinery, no possibilities for passenger cars and commercial vans.
