Influence of heat flowmeters on thermal measurements
Thierry Langlet, Jean Roucoult, Omar Douzane, Jean-Marie Devisme
The measurement of heat flows in the engineering field is relevant to thermophysical characteristics of materials in the study of the behaviour of a wall or the achievement of an energy balance in a building. Nevertheless, the utilisation of heat flowmeters in a thermal circuit has to be accompanied by some precautions, notably for materials which are slightly heat conducting. The perturbation induced by the presence of the heat flowmeter is in fact often difficult to evaluate.
