FIRE EXTINGUISHING AGENT CONCENTRATION MEASURING SYSTEM AND METHOD OF MEASURING A FIRE EXTINGUISHING AGENT WITHIN AN ENVIRONMENT

摘要

A fire extinguishing agent concentration measuring system having a first window, a second window positioned relative to the first window thereby defining a sensing volume between the first window and the second window, and a structure positioned relative to the first window and the second window configured to cause fluid flowing into the sensing volume from an environment within which the fire extinguishing agent concentration measuring system is placed to swirl within the sensing volume.
