If the flow of gas is too low, inadequate shielding generates porosity, oxidation, and weak welds. If the flow of gas is too high, turbulence sucks in air with the same result.
To protect occupants, international regulations like GTR 20 and GB 38031-2025 mandate early detection of such dangers and timely warnings to ensure safe evacuation. Meeting present and future requirements demands reliable sensor technology.
