Abstract

L'invention concerne un procédé et des dispositifs pour mesurer la viscosité d'un liquide. Elle utilise, à cet effet, un viscosimètre du type Searle-Couette, à faible entrefer entre cylindre interne et cylindre externe et dont le cylindre interne est animé d'un mouvement de rotation, la vitesse V du cylindre interne est progressivement orientée en fonction du temps t selon une loi du type : V = k t**n où k est une constante et où 0,2 <= n <= 5. L'invention s'applique à la mesure de la viscosité.
