A system for inspecting spray nozzles includes a nozzle operatively connected to a source of pressurized liquid for issuing a spray from the nozzle. The system also includes a sensor positioned to detect frequencies of resonant modes in the spray. The nozzle and sensor can each be mounted to a spray...
