A Process of determining at least one thermal property of a fluid under investigation with a thermal sensor, wherein 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 T sens at the first and/or second sensor element said fluid under investigation c) Extracting one or more thermal property of the fluid under investigation by applying the said temperature T sens to said calibrated reduced order model.
