EnergyTech 601

Flue Gas Flow Monitor

The EnergyTech 601/602 represents the latest generation of CODEL’s unique flow monitors


The EnergyTech 601/602 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).

The EnergyTech 601/602 is a standalone unit which can be easily integrated into an existing or proposed CEMS system. It includes a dedicated Data Dislpay Unit for local data interrogation.
