A Process of determining at least one thermal property of a fluid under investigation with a thermal sensor. The thermal sensor has at least a first sensor element that is heated to provide heat to the fluid under investigation. The first or a second sensor that can sense the temperature of the fluid under investigation, wherein the process is characterized by the following steps: a) Providing a calibrated reduced order model which is calibrated with one or more thermal properties of at least a second and a third fluid; b) (Applying an amount of heat to the fluid under investigation by the first sensor element and) measuring the temperature Tsens at the first and/or second sensor element said fluid under investigation; and c) Extracting one or more thermal property of the fluid under investigation by applying the said temperature Tsens to said calibrated reduced order model.
