AI Technical Summary
Existing gas concentration measurement equipment suffers from problems such as inconsistent accuracy, uneven air mixing, and complex traceability relationships, which affect the accuracy and consistency of measurement data.
A vertical cylindrical container is used, and bubbles are released uniformly at the bottom to form a stable and uniform two-phase flow field of water and gas. Utilizing the natural floating characteristic of bubbles, a standard volume gas concentration source material generating device is constructed through a bubble plate and a pressure gas source, which simplifies the measurement process and traces back to the basic length parameter.
It achieves a simple equipment structure, low cost, and consistent measurement accuracy, provides a reliable standard gas-mixing environment, is suitable for the calibration of various gas-mixing concentration measuring instruments or sensors, reduces the number of equipment and layout space, and is energy-saving and environmentally friendly.
