VCEM 5100 Insitu Flue Gas Flow Monitor
The VCEM5100 represents the latest generation of unique flow monitors from Forbes Marshall. It provides non-contact measurement of gas velocity using a time-delay correlation of flue gas infrared emissions received by two detectors placed at a fixed distance apart. This technique is suitable for all combustion gases including hot gases and gases with a high dust burden.
