Title (EN) METHOD FOR MEASURING AND/OR CONTROLLING THE INTERFACIAL SURFACE TENSION OF LIQUIDS
(FR) PROCEDE DE MESURE ET/OU DE CONTROLE DE LA TENSION SUPERFICIELLE DE LIQUIDES
Abstract: front page image
(EN)Method for measuring and/or controlling the interfacial surface tension of liquids by generating vibrations in a circular area of the surface (5) of the liquid, thereby creating a system of stationary waves in concentric rings which may be defined by measuring the intensity of a reflected light beam (L, L'). The method is characterized by an easy operation and is also appropriate to control automatically the interfacial surface tension.
(FR)Procédé pour mesurer et/ou contrôler la tension superficielle de liquides en provoquant des vibrations dans une zone circulaire de la surface (5) du liquide, ce qui crée un système d'ondes stationnaires en anneaux concentriques qui peuvent être définies en mesurant l'intensité d'un rayon lumineux (L, L') réfléchi. Ce procédé se caractérise par son utilisation aisée et convient également pour contrôler automatiquement la tension superficielle.
