Fuel consumption monitoring is an advanced function of GPS. Fuel consumption monitoring is generally an extended function of GPS positioning equipment. Generally speaking, an infrared sensing device is added to the fuel tank. In this way, the real-time height of the oil in the oil tank can be transmitted to the GPS platform. Some GPS manufacturers judge whether to steal oil by displaying and analyzing the coordinate curve of vehicle speed and oil level height in GPS management software. If the speed on the GPS is 0, that is, the car stops and the oil level drops obviously, it is probably stealing oil.

The functions of GPS positioning system generally include: positioning, driving trajectory, vehicle speed, alarm, overspeed alarm, snapshot, fuel consumption and so on.
