Abstract
A solid particle counting system for measuring solid particle number concentrations from engine or vehicle exhausts in real-time includes an evaporation unit, a diluter arrangement, and a particle counter. The diluter arrangement mixes the dilution gas with the gases from the evaporation unit at a dilution ratio, and the diluter arrangement includes a flow meter located upstream of the evaporation unit for measuring the flow of gases into the evaporation unit which, in turn, flow into the diluter arrangement.
