Patent abstract
A perforated mixing plate and is fluid passage are used in conjunction with a dilution tunnel to prevent particulate matter from collecting on the sampling system components. An inlet of a sampling probe is offset from the centerline of the dilution tunnel to a location corresponding to an average particulate matter concentration along a flow profile of a sample mixture to reduce the length of the dilution tunnel.
