ABSTRACT:
The temperature of fluid (gas or liquid) flowing in a duct 10a having axis 21 is measured using a collar 12 having an inner face 17 embracing the tube and having two axial bores 16, 18 at different lateral distances from the duct axis which receive temperature sensors 8, 9 connected to recording and monitoring devices 20, 22. A heater 14 is provided on the outside of the collar and when there is no lateral heat flux in the collar and the wall of the duct the temperature of the fluid equals the temperature of the sensors.
