【Abstract】 A optical method for particle sizing and concentration,the so-called light transmission fluctuation method,is presented.For on-line monitoring in industrial scale,this principle is robust,simple and reliable due to its low cost and good flexibility.Several factors limiting measurement range of particle size and concentration are also discussed in detail.Furthermore,the feasibility of application of this method to measurement of polydisperse and high concentrated particle systems is predicted.更多还原
