VCEM5000/5100 Gas Velocity Monitor


  • Non-contact infra-red sensing
  • Continuous measurement
  • Suitable for hot and dirty gases
  • No limit on upper gas temperature
  • No moving components
  • High availability, low maintenance requirement
The VCEM 5000/51000 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 extend the time between maintenance periods and window cleaning (typically 1 year).
