Beschreibung
Zusammenfassung:	A device arranged for measuring a level of a liquid in a container. The device has a sensor, arranged to sense a pressure of a liquid in a tube, a pump arranged to pump the liquid from the container through the tube, and a valve located along the tube between the sensor and the pump and arranged to impede back flow of the liquid into the container when the pump stops pumping the liquid. The device is arranged to measure the level of the liquid into the container on the basis of the hydrostatic pressure measured by the sensor after each stop of the pump. Also disclosed is a method for measuring a level of a liquid in a container by a pressure sensor.
