摘要： 57 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.

摘要翻译： 所公开的使用多孔颗粒陶瓷示踪剂和光学仪器测量流体的方法的特征在于使用直径在0.5至150μm范围内的球形颗粒作为示踪剂。 由于用于流量测量的示踪剂颗粒是球形的，所以由光学传感器装置检测的散射光的截面面积与颗粒的取向无关。 此外，球形颗粒没有可能引起连接的表面不规则性，使得单个颗粒在跟踪流体流动时不凝聚，从而有助于提高测量精度。
