Hardware: 4G GPS tracker S70 +AS10 capacitive fuel sensor
Vehicle type: truck
Description: as below picture indicates, the green line fuel graph is fluctuated during moving, corresponding with the blue line speed change. One thing need your attention is that when the speed up, the fuel is up too.
This fluctuation is over the fuel sensor accuracy error rate, it is abnormal, but why?
The main reason is from the incorrect fuel sensor installation position.
As below picture green arrow shows, this AS10 fuel sensor was installed on the edge of the fuel tank. On the edge, the gasoline/diesel fluctuates more during moving, and reflects on the fuel sensor results.
Correct installation position is the centre position of the fuel tank for smooth fuel level graph.
