Abstract:
1. A method for measuring particle content, comprising: routing a plurality of streams, via a plurality of tubes, from a plurality of sampling points where particle content concentrations are to be measured, wherein the plurality of sampling points comprises a plurality of compartments that are fluidly isolated from each other, wherein each sampling point comprises an injector for injecting one or more of an extinguishing agent and a suppression agent at each sampling point, wherein the one or more of the extinguishing agent and the suppression agent injected at one of the sampling points is isolated and independent from the one or more of the extinguishing agent and the suppression agent injected at other sampling points; separately measuring concentration of particle content in each of the plurality of streams, wherein the measuring is based on one or both of: determining whether the measured concentration of particle content from each sampling point is indicative of an appropriate concentration of the one or more of the extinguishing agent and the suppression agent at each sampling point.
