Measurement of solid, aerosol, vapor, liquid and gaseous concentration and particle size

摘要

A method and apparatus for measuring particle content in a stream, comprising routing the stream, via a plurality of tubes, from a plurality of sampling points where particle content concentrations are to be measured. The concentration of particle content in the stream may be measured. The measurement may be based on determination, via a sensor for example, of an electrostatic charge of the particles as the particles, and/or based on counting of a number of particles in the stream, such as using a counter tracking light emitted from a light source. The measured concentration of particle content may be analyzed to determine if it is indicative of an appropriate concentration of measured particles in the stream. The particles may comprise extinguishing and/or suppression agent particles.

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:
counting a number of particles; anddetermining an electrostatic charge of the particles; and 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.
