Dual Pass Opacity / Dust Monitor

The DCEM2100 is a CEMS dual-pass dust monitor configured for the continuous measurement of opacity and dust in flue gases.

CEMS Dust Stack Emission Monitors analyser

Dust Monitor Overview

The DCEM2100 dust monitor provides a continuous measurement of opacity or dust concentration in flue gases by continuously measuring the transmissivity of visible light across a process duct or stack.

Its dual-pass optical arrangement is based on twin transmissometers measuring in opposing directions through the same section of the gas stream, providing not only an accurate average of the dust loading, but also providing a unique dynamic assessment of any misalignment errors due to stack movement.
