Abstract
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: checking the validity of the measurement performed by said first ultrasound subsystem (S10); when it is detected that the measurement of said first ultrasound system is not valid: (a) checking (S22) the validity of the measurement performed by said second ultrasound subsystem; (b) determining (S24, S25, S26) a quantity of liquid, which quantity being based on a result of the validity check at step (a).
