Continuous on-line analysis often only considers the density of the emissions (e.g mg/Nm3) In order to obtain a measurement of total emissions for pollution monitoring (e.g kg/hr) it is necessary to either calculate or measure flow within the gas stream. The VCEM5100 provides non-contact measurement of gas velocity using a time-delay correlation of flue gas infrared emissions received by two detectors spaced a fixed distance apart. Gas velocities ranging from 1m/sec to 50m/sec can be measured. The technique is suitable for all combustion gases including hot gases and gases with a high dust burden. Designed as a stand-alone instrument.
