Abstract: A method for determining a temperature of a fluid flowing through a pipe section includes: determining a temperature of the pipe section; obtaining a reference temperature at a distance from a surface of the pipe section; determining a heat transfer behaviour, in particular a thermal resistance, of a boundary layer of the fluid on an inner wall of the pipe section based on at least one material property and/or at least one value of a state variable of the fluid; and determining the temperature of the fluid based on the heat transfer behaviour of the boundary layer, a heat transfer behavior, in particular a thermal resistance, of the pipe section, the temperature of the pipe section, and the reference temperature.

Abstract: A method for testing a temperature measuring instrument is presented, where the instrument includes at least one sensor that changes its electrical resistance, and/or an electrical voltage that it produces, in response to being exposed to a change in temperature, and where the instrument is configured to be coupled to an object of interest. The method includes changing the temperature of at least one sensor by an amount that is detectable given the measurement resolution of the at least one sensor, by driving an electrical manipulation current through this sensor; obtaining one or measurement values from at least one sensor; and evaluating a state of the measuring instrument, a state of one or more of its sensors, and/or a state of a coupling to an object of interest, from the one or more measurement values.
