A device for measuring the internal temperature of a reforming tube including a first structure having an axial part of tubular shape positioned in the lengthwise direction of a reforming tube and a radial part projecting radially towards the central axis of the reforming tube, a second structure of oblong shape having at least one thermocouple made of welded Nicrosil/Nisil conductors arranged longitudinally against the axial part and radially against the radial part, and an outer sheath enveloping the first structure and the second structure.

Device for measuring the inner temperature of a reforming tube

A sensor of a multiphase flow meter is operated to determine a physical property attributable to multiphase fluid flow in a conduit of the multiphase flow meter. A stationarity of the multiphase fluid flow is determined based on the determined physical property in actual conditions compared to expected noise of the sensor in stationary flow conditions. A flow model variable is selected from a plurality of flow model variables based on a gas content of the multiphase fluid flow and the determined stationarity. The multiphase fluid flow is then modeled by adjusting the selected flow model variable.
