Various embodiments include methods and systems to dilute a sampled particle-laden aerosol stream. In one embodiment, a system to dilute a sampled aerosol stream includes an aerosol sample inlet. A filter is coupled in fluid communication with and in parallel with a flow-monitoring device to receive the sampled aerosol stream from the aerosol sample inlet. The flow-monitoring device is configured to allow for a passage of particles contained in the sampled aerosol stream. A pressure sensor and a temperature sensor monitor the filter and the flow-monitoring device. An output from the filter and the flow-monitoring device may be directed to particle measurement or particle sizing instrumentation. An actual dilution ratio of the output sent to the particle measurement or particle sizing instrumentation is determined based on a nominal flowrate of the flow-monitoring device and thermodynamic properties of a gas comprising the aerosol stream. Other methods and apparatuses are disclosed.
