Abstract: A device for sensing the pressure of a medium within a fluid medium received in a container includes a pressure sensor associated with a screen or joined thereto. The screen shields the pressure sensor at least on one side from swirls formed in the medium, for example during filling or emptying of the container. The pressure sensor communicates with an external data-processing unit for evaluation of sensor data and the screen is joined to a pump lance of a container pump in the region of a pump foot and together therewith forms a measuring chamber, in which the pressure sensor is received. The pressure sensor is thereby decoupled by the screen from influences of dynamic pressure and is placed in the container in such a way that it is able to sense the pressure on the spot, but without interfering flow conditions.
