Abstract
The linear relation between the particle concentration and the output voltage of a light extinctiometer used to measure particle concentrations has been derived and calibrated. A time integration method was introduced to determine the characteristic parameter of such a measuring system. This characteristic parameter which is proportional to the extinction coefficient is found to be in good agreement with its theoretical value. As an example, in a vertical tube the increasing particle concentration was measured behind a developing flat interface between a gas and a gas-particle mixture as a function of time.
