Abstract

The present invention provides a method and a system for level measurement of liquids in a mobile device. The system comprises a measuring device, which is arranged for a first measurement of at least one first liquid level in a first container for liquids arranged in the mobile device. The system also comprises a first determination device, which is arranged to determine an impact which at least one ambient factor may have on the measurement of the liquid level, wherein the at least one ambient factor influences the mobile device in such a manner that the measuring values are impacted. The system also comprises a second determination device, which is arranged to determine whether the level measurement is reliable. The determination of the measuring value's reliability is based, according to the invention, on the impact which the at least one ambient factor has had on the level measurement's measuring values.
