Gas Velocity Monitor
The VCEM5000/5100 represents the latest generation of CODEL’s unique flow monitors.
The VCEM 5000/5100 represents the latest generation of CODEL’s unique flow monitors. These systems measure the velocity of stack gases using a highly accurate time of flight measurement that is derived from a cross correlation analysis of the infra-red emissions of the turbulent gas.
Two robust infrared detectors are used for the prime sensing, mounted on the stack or duct typically 1m apart in the direction of flow. High efficiency air curtains are fitted to considerably exten the time between maintenance and periods and window cleaning (typically 1 year).
