Aerosol generator for e.g. gas flow analysis device, includes independently operated nozzle units with different numbers of gas nozzles

摘要

Nozzle units (39-42) containing different numbers of gas nozzles can be operated independently via separate valves (9-12). The nozzles are connected to feed lines (2, 3) for a pressurised gas and located beneath the surface of the liquid (20) used to form the aerosol.
