[0002] Gas flow rate detection technology plays a crucial role in modern scientific research and technological development. It is widely used in various fields such as chemistry, metallurgy, physics, biology, and environmental science, providing strong assurance for the accuracy and safety of experiments. Gas flow rate detection refers to the measurement of gas flow velocity and volume, which is essential for the accuracy and safety of experiments.

[0003] In the field of biology, cell culture refers to a method of simulating the in vivo environment (sterility, suitable temperature, pH, and certain nutritional conditions, etc.) in vitro to enable cells to survive, grow, reproduce, and maintain their main structures and functions. Gas is one of the essential conditions for cell culture, primarily oxygen (O2) and carbon dioxide (CO2). O2 participates in the tricarboxylic acid cycle, producing energy for cell growth and proliferation and synthesizing various components needed for cell growth. The ratio of carbon dioxide to oxygen must be continuously adjusted during cell culture to maintain the required gaseous conditions.
