Abstract: 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.

Abstract: A magneto-inductive flow measuring device including a coil arrangement and a circuit for controlling a supply voltage of the coil arrangement. The circuit is designed to provide the supply voltage of the coil arrangement with a voltage curve sequenced as follows: A) the voltage rises from a starting voltage I up to an overvoltage II; B) in given cases, the voltage is held at the overvoltage II; C) the voltage falls from the overvoltage II down to a holding voltage V. The circuit controls the fall of the voltage from the overvoltage down to the holding voltage by tuning the voltage to at least two or more predetermined, intermediate, desired values III, IV.
