ABSTRACT:
Apparatus for measuring the concentration of solid particles in a fluid stream wherein a critical flow orifice produces a stream of fluid having a constant velocity, a surface for effecting triboelectric charging of the particles in the gas in the constant velocity stream and a charge measuring device for measuring the charges thus triboelectrically imparted to the particles. The apparatus overcomes the inaccuracies which occur in prior art particle detectors when such particle detectors are used to monitor fluid streams whose velocity is variable e.g. air intake systems for internal combustion engines which operate at varying speeds.
