The example of a gas flowing through an orifice into the rarefied surrounding space is used to demonstrate the possibility of using clusters for diagnosing gas flows. For conditions studied (it takes a cluster about the same time to relax to the gas velocity is it does to reach the orifice), information on the flow parameters inside the chamber is obtained from the measurement of the cluster drift velocity after the passage through the orifice for various gas consumptions. Other possible uses of clusters in gas flow diagnostics are discussed as well.
