Zusammenfassung:	A method for determining an average temperature of a fluid in a closable container (1) comprising: providing a duct (4) with first opening (11a) and second opening (11b), positioning a flow preventing element (7) in the duct (4), positioning a density sensor (3) or first pressure sensor (3) inside the duct (4) or container (1), attaching the duct (4) to a container outside wall, stabilizing a temperature of the duct wall (10) to a constant reference value, determining a difference between a first pressure of the fluid on one side and a second pressure of the fluid on the other side of the flow preventing element (7), measuring a local density of the fluid by the density sensor (3) and/or a local pressure by the first pressure sensor (3), and deriving the average temperature from the local differential pressure, the local density and the reference duct temperature.
