Title: PROCESS OF DETERMINING AT LEAST ONE THERMAL PROPERTY OF A FLUID UNDER INVESTIGATION WITH A THERMAL SENSOR
Abstract:
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 Tsens 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 Tsens to said calibrated reduced order model.
