Abstract

L'invention concerne un dispositif calorimétrique mesurant par des sondes thermométriques les températures dans les conduites de départ et de retour du fluide en circulation ainsi que son débit. On a à ce propos pris soin que le montage pour la détermination de la quantité de chaleur à partir des trois valeurs de mesure, se réetalonne à partir des trois valeurs de mesure, se réétalonne automatiquement de façon continuelle. On prend en considération la fonction de la dépendance de chaleur spécifique et de la densité de la température au fluide en circulation.
