It is proposed a method for determining a quantity of a liquid in a tank, the tank comprising: a first ultrasound subsystem capable of measuring level of liquid present above a predetermined threshold level within the tank; and at least one second ultrasound subsystem, said second ultrasound subsystem being associated with a sensing area within the tank and being configured to measure a parameter characteristic of the liquid, said sensing area being located below the predetermined threshold level. The method comprises in the steps of: &#x2014;checking the validity of the measurement performed by said first ultrasound subsystem (S); &#x2014;when it is detected that the measurement of said first ultrasound system is not valid: (a) checking (S) the validity of the measurement performed by said second ultrasound subsystem; (b) determining (S, S, S) a quantity of liquid, which quantity being based on a result of the validity check at step (a).

Method and system for determining a quantity of liquid in a tank

The invention concerns a tank () of fluid () for a motor vehicle (), comprising a body () arranged to receive the fluid () and a system () for measuring a parameter of the fluid () in the tank () from an acoustic wave. According to the invention, the acoustic wave () is generated by another system (), the main function of which is not that of emitting an acoustic wave.
