摘要：

The development of the manometric particle size analysis by sedimentation under gravity is described, giving examples of various measuring arrangements. It has been shown, how the disturbing effects, occurring in this analysis, could be gradually eliminated without losing any advantages. If dispersion and evaluation of the measurements are included in the automation of the process, the manometric particle size analysis becomes considerably simplified and easier to perform. Progress in the measurement of very small pressure differences in liquids has allowed the reduction of the sedimentation height and hence the speeding up of the experiment. Further measures to lower the time consumption are indicated. An extension of the range of application can be expected for this method in the future.
