An apparatus is disclosed for detecting particles and changes in particle size, for example as a result of flocculation, in a suspension of particles in a fluid medium. The apparatus comprises means (6) for directing a beam of light at the suspension, a detector (7) for detecting light emerging from the suspension and producing an output signal in response thereto, and means (8) for generating from the output signal of the detector (7) a signal representing the power of the fluctuating component of the said output signal of the detector (7) or a function of that power.
本发明公开了一种仪器,用于检测流体介质中颗粒悬浮液中的颗粒和颗粒大小的变化,例如絮凝的结果。该装置包括用于将一束光射向悬浮液的装置(6)、用于检测从悬浮液中射出的光并随之产生输出信号的检测器(7)以及用于从检测器(7)的输出信号中产生代表检测器(7)的上述输出信号的波动分量的功率或该功率的函数的信号的装置(8)。
