Velocity survey with powderizer and agent flow indicator

摘要

Disclosed is a measurement system for a dry powder agent including a nozzle to direct the dry powder agent, and an indicator operable to recognize a dry powder agent discharge event. In an exemplary method, a velocity of the powder exiting the 5 nozzle may be computed, and an agent concentration calibration curve may be selected.
