Abstract

Method and device for simultaneous in-situ determination of particle size and mass concentration of fluid-borne particles, wherein the device includes a sensor unit comprising a sending unit and a receiver, a laser coupled to the sensor unit, a detector coupled to the sensor unit, and a microprocessor coupled to the sensor unit, wherein the sensor unit is at least one of adjustable in cross section and variable in diameter and wherein the sensor unit is arranged to one of protrude into the fluid-borne particles and wrap around the fluid-borne particles. The method includes placing the sensor unit adjacent a pipe having a gas flow and simultaneously determining a particle size and a mass concentration of the fluid-borne particles in the gas flow.
