High-Pressure Electromagnetic Flow Meters for Nuclear Power and Hydrogen Refueling Station Working Conditions
Nuclear power plants and high-pressure hydrogen refueling stations represent two typical ultra-strict industrial scenarios, featuring high operating pressure, severe pipeline vibration, stringent safety standards and continuous long-cycle operation. Conventional flow meters are prone to structural deformation, seal failure and signal instability under high-pressure loads, failing to meet the precision and safety monitoring requirements of core energy facilities.
Alkaline water electrolysis dominates industrial green hydrogen production, relying on circulating lye such as potassium hydroxide and sodium hydroxide to conduct electricity, balance temperature and stabilize electrolytic reactions.
The high-concentration alkaline medium features strong corrosiveness and easy crystallization, bringing severe challenges to traditional flow measurement equipment. Conventional flow meters are prone to electrode corrosion, lining aging and scale coverage, resulting in flow signal drift and unstable hydrogen production efficiency. As the most reliable monitoring device for lye circulation systems, specially configured anti-corrosion electromagnetic flow meters adapt to the harsh characteristics of alkaline electrolysis working conditions
