EnergyTech 101

Single Pass Opacity / Dust Monitor

A single-pass optical device which uses visible light to measure the opacity and dust within the flue gas.


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.
