ABSTRACT:
An automatic isokinetic sampling device for measuring aerosols in a fluid flow has a vacuum or suction pressure device attached to the end of a tubular collector which is placed in the path of the fluid flow. A differential air flow sensor senses and determines the difference in velocity between the fluid flow outside the tubular collector and that portion of the fluid flow received by the tubular collector. A filter for collecting a sample the aerosols in the fluid flow is placed along the straight downwind path of the fluid flow and within the tubular collector. As the fluid flow velocity changes the flow inside the tubular collector is equalized to the flow outside the tubular collector providing isokinetic sampling of the aerosols.
