The disclosed method of measuring the flow of a fluid with a porous particulate ceramic tracer and an optical instrument is characterized in that spherical particles having diameters in the range of 0.5 to 150 µm are used as the tracer. Inasmuch as the tracer particles for flow measurement are spherical, the sectional area of scattered light to be detected by an optical sensor means is constant regardless of the orientation of particles. Furthermore, spherical particles have no surface irregularities that might cause concatenation so that individual particles are not agglomerated in tracking a fluid flow, thus contributing to improved measurement accuracy.

Cette invention concerne un méthode de mesurage du débit d'un fluide au moyen d'un traceur particulaire en céramique poreuse et d'un instrument optique, les particules sphériques utilisées ayant un diamètre compris entre 0,5 et 150 m. Dans la mesure où les particules utilisées comme traceurs sont sphériques, la section du faisceau de lumière réfléchi à être détecté par l'instrument précité est constante peu importe l'orientation des particules. De plus, les particules sphériques ne présentent aucune irrégularité de surface susceptible d'entraîner une concaténation favorisant leur agglomération qui peut entacher la précision de la mesure.
