Patent abstract

A solid particle counting system for measuring solid particle number concentrations from engine or vehicle exhausts in real-time includes a flow splitter having an inlet, a sample outlet, and a by-pass outlet arranged such that a main flow enters the inlet and changes direction to exit the by-pass outlet. A sample flow from the main flow exits the sample outlet. The flow splitter further includes a guiding element arranged such that particles at a sampling location upstream of the main flow direction change are guided to the sample outlet.
