AI Technical Summary
Existing gas-mixing concentration instrument calibration systems suffer from inconsistent measurement accuracy, uneven air mixing, and complex traceability issues, making it difficult to provide a stable and uniform water-gas two-phase flow field and affecting the accuracy and authority of measurement data.
A steady-state cylindrical container is used to uniformly release bubbles from the bottom. Combined with data acquisition and processing devices, a uniform water-gas two-phase flow field is formed. Accurate volumetric gas concentration measurement is achieved through facilities such as bubble pans and level gauges, simplifying the metering process.
It provides a stable and reliable standard volumetric gas concentration source material, simplifies the equipment structure, reduces costs, and improves measurement accuracy and consistency, making it suitable for small-scale laboratory or office environments.
