The EnergyTech 101 Opacity Monitors consist of a visible light transmitter and receiver arrangement with digital data processing in a local display unit. The monitors can display data in either opacity, extinction or dust density in mg/m3 or normalised dust density in mg/Nm3. The EnergyTech 101 possesses four analogue inputs for normalisation data; temperature, oxygen, pressure and water vapour.

The DCEM2100 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.

The EnergyTech 301 is a low cost dust monitor using well-proven tribo-electric technology providing accurate and rapid results. The EnergyTech 301 requires no critical alignment and has no optical surfaces to keep clean. The sensor is easy to install, requiring only a simple probe and is ideal for small duct sizes. Minimal maintenance is required, infrequent probe cleaning and low installation costs make this technology extremely attractive for dust collector monitoring.
