Abstract

a. Installation pour la surveillance de l'état d'écoulement d'un fluide à travers un tuyau, comprenant une source de chaleur en liaison de conduction thermique avec la paroi du tuyau, ainsi qu'un palpeur détecteur de température. b. Installation caractérisée par un corps métallique à conductibilité thermique élevée, qui est relié à bonne conduction de la chaleur à la paroi de tuyau, qui, d'une part, porte la source de chaleur, et qui, d'autre part, contient le palpeur de température dans un logement compris entre le siège de la source de chaleur et la paroi intérieure du tuyau. c. Installation applicable à des conducteurs de transport de gaz liquéfié à bas point d'ébullition.
