ABSTRACT:
A tank display system for a tank filled with fuel, the tank being divided into a main tank and a supplementary tank, has a level limit switch which responds when the main tank is almost empty. If the switch gives off a signal, then a valve is opened, allowing fuel to flow from the supplementary tank into a flood cup of the main tank. Furthermore, this signal activates a unit for detection of fuel consumption, which unit calculates the remaining volume of fuel in the supplementary tank, which volume decreases as a result of the consumption of fuel. As starting volume for the calculation, the completely filled supplementary tank is used. The precise remaining volume of fuel is displayed.
