A device for measuring the liquid level inside a tire that includes a stem of a tire pressure valve that includes a first electrode, a second electrode, and an isolated part between the electrodes, a power source, and an electric circuit. The stem is fixed to the rim of the tire in a way that the electrodes' upper parts protrude outside the rim and the electrodes' lower parts protrude inside the rim. The lower parts are immersed inside the liquid inside the tire when the tire pressure valve faces the ground. The electrodes' upper parts are connected to the power source and to the electric circuit that measures an electric property of the liquid between the lower parts of the electrodes, and the intensity of this property represents the liquid level and can be used for calculation this level.
