Method and device for measuring the volume of fuel contained in the tank of a motor vehicle, comprising a conventional float gauge. Since the indication of the gauge 10 is not reliable above an upper limit V2 and below a lower limit V1, a display is given on the display 49, outside the significant range of the gauge 10, of a volume V obtained by calculating the consumption C as a function of the speed S by means of a microprocessor 30, or the difference between the capacity of the tank VMAX and the calculated consumed volume C of fuel, when V is greater than V2, or the difference between the lower limit volume V1 and this consumed volume C, when V is less than V1. Application to hire cars. <IMAGE>
