2. Measurement Principle – Gas flow is rarely laminar. Turbulence in the flow produces a series of swirling eddies and vortices that are transported with the bulk flow. Infrared radiation, emitted by a hot gas system, is characterised by a flickering signal resulting from the swirling effect of these vortices. Two infrared detectors, placed a […]

1.2. V-CEM5000 Basic Principles – The V-CEM5000 uses an infrared cross-correlation technique that requires no contact with the flue gases. The method used resembles flow measurement with chemical dye or radioactive tracers, where the velocity is derived from the transport time of the tracer between two measuring points a known distance apart. However, instead of […]

1.2. GCEM4000 Basic Principles The GCEM4000 analyser uses an in-situ probe set into a duct to measure the concentration of gases of interest. Figure 2 illustrates the arrangement. The in-situ tube includes a section that allows the diffusion of flue gases into the measurement zone or the dispersion of purge or calibration gas out of […]

2. Measurement Principle 2.1. CO – The analyser comprises an infrared source assembly mounted on one side of the measurement chamber. On the opposite side of the measurement chamber is the receiver. – The source consists of a small black-body emitter and gas wheel assembly. The wheel is rotated by a stepper motor at a […]

3. Principles of Operation When a particle moving in a duct collides with (or passes near) a probe that is grounded to earth, a transfer of charge takes place from the particle to the conductor. This is known as tribo-electricity or frictional electrification and results in a charge being imparted to the probe…[…] Energy_tech_301_operating_manual

2.2 Principles / Modes of Operation – Gas levels are determined by measuring the absorption of infrared radiation, transmitted through the flue gas, in a wave band sensitive to absorption by the measurement gas. The EnergyTech 401 has two detectors; one measuring the radiation directly to provide a live output, sensitive to the measurement gas, […]
