Industrial process control instruments, including flow meters and gas flow meters, are critical core equipment in modern industrial production. They can accurately monitor and control key parameters such as flow rate, not only improving production efficiency and reducing energy consumption costs, but also mitigating safety risks in high-temperature and high-pressure conditions and ensuring stable product quality. Their applications span various fields, including petrochemicals, power generation, metallurgy, and pharmaceuticals, such as raw material transportation metering in the petrochemical industry, steam flow monitoring in the power industry, and precise ingredient dispensing in the pharmaceutical industry. They provide core support for industrial automation and intelligent transformation, and are an important guarantee for enterprises to enhance their competitiveness.
