System Overview:
The closed-loop eddy current related flux observation system is a high-performance and highly reliable flux observation system independently developed by Cenfeng Technology. The system adopts the TDLAS principle and mainly consists of a closed-circuit gas analyzer, a three-dimensional ultrasonic anemometer, a data collector, and other accessories and supporting operating software. It can be used for long-term monitoring of carbon dioxide, water vapor, heat, and momentum exchange between the atmosphere and ecosystems. The closed-loop gas analyzer designed specifically for vortex related flux observation can simultaneously measure the absolute density of carbon dioxide and water vapor, as well as the temperature and pressure inside the sampling chamber. It adopts a small sampling chamber design of 9mL, greatly reducing the sampling residence time. At the same time, the power consumption of the system has been significantly reduced to within 10W, making it suitable for solar power supply.
System Advantages:
(1) Localization, independent and controllable;
(2) Technology *, the industry first uses TDLAS to achieve closed-loop flux monitoring;
(3) The ultra small 9mL gas pool volume design reduces sampling dwell time, achieves high-frequency response, and is matched with a small flow air pump to reduce system power consumption.
