Title (EN) FLUID VOLUME MEASUREMENT DEVICE
(FR) DISPOSITIF DE MESURE DU VOLUME D'UN FLUIDE
Abstract:
(EN) A fluid volume measuring device includes a rigid support (3) of annular configuration at one end of which a resilient membrane (1) is secured. Membrane (1) includes an electrically conductive portion (2) and, in use, is arranged to support the fluid whose volume is to be measured. The membrane resiliently deforms causing deformation of the electrically conductive portion (2) giving rise to a change of resistance in the electrically conductive portion (2) which is measured by a measuring device (18). The membrane (1) and the electrically conductive portion (2) are each silicone elastomers.
(FR) Un dispositif de mesure du volume d'un fluide comprend un support rigide (3) de configuration annulaire, à une extrémité duquel est fixée une membrane résiliente (1). La membrane (1) comprend une partie électriquement conductrice (2) et, lors de l'utilisation, elle supporte le fluide dont il faut mesurer le volume. La membrane se déforme de manière résiliente en provoquant la déformation de la partie électriquement conductrice (2), ce qui produit une variation de la résistance de la partie électriquement conductrice (2), variation mesurée par un dispositif de mesure (18). La membrane (1) et la partie électriquement conductrice (2) se composent d'élastomères au silicone.
