- Model PCME STACK 181 WS - Particulate CEM for Wet Gas Stream



US EPA PS11 capable ProScatter™ particulate CEM for the extractive sampling and measurement of particulate in saturated wet gas streams.

  • Robust design with no moving parts in the optical system
  • Available for use in high-temperature or corrosive stack conditions and Ex hazardous zones
  • Easy to fit multi-patterned flange
  • Adjustable monitoring depth to ensure sampling in the most representative part of the flow path
  • For use as PM-CPMS or PM-CEMS that need to comply with US EPA PS-11
  • ProScatter® technology offers enhanced measurement due to reduced cross-sensitivity of particle type and size
  • Features automatic zero and upscale checks that fully challenge the system’s ability to measure forward-scattered light and satisfy daily drift checks
  • Easily audited with manual filters

  • Stacks below dew point / with water droplets
  • After wet scrubber arrestment plant
  • After Flue Gas Desulphurisation (FGD) plant
  • Flue gas velocity range 1-20m/s
  • Corrosive flue gases (corrosion protection option)
  • Variable particulate size
