With the rapid expansion of the hydrogen energy industry, hydrogen production, storage, transportation and refueling equipment have put forward higher requirements for industrial pressure measurement. Hydrogen has extremely small molecular particles, strong permeability and special chemical characteristics, which easily cause hydrogen embrittlement, sensor zero drift and equipment failure of ordinary pressure transmitters.

With the rapid development of green hydrogen energy, hydrogenation chemical engineering and hydrogen refueling infrastructure, stable pressure monitoring has become the core foundation for process safety. Hydrogen is the smallest molecule, which easily penetrates ordinary metal materials and triggers hydrogen permeation and hydrogen embrittlement. Conventional industrial pressure transmitters suffer zero drift, diaphragm damage and premature failure under long-term hydrogen exposure.

Continuous hydrogenation technology is widely adopted in petrochemical fine chemical, pharmaceutical and new energy industries, which relies on stable pressure control to guarantee catalytic reaction efficiency and production safety. As core field measuring instruments, pressure transmitters undertake real-time pressure collection, signal transmission and safety interlock tasks for continuous hydrogenation units.

Metallurgical production extensively involves high-temperature, high-abrasion slurry media such as ore pulp, tailings slurry, and smelting wastewater mixed with solid particles. These harsh working conditions easily cause lining wear, electrode abrasion, and measurement instability for conventional flow detection equipment, seriously affecting process batching accuracy and production safety.

Key points for using electromagnetic flowmeters in municipal wastewater containing high levels of silt and impurities

The chemical industry extensively utilizes and transports highly corrosive media, including strong acids, strong alkalis, and salt solutions, which pose severe challenges to conventional flow measurement equipment. Traditional mechanical and ultrasonic flow meters are prone to corrosion, scaling, structural damage and inaccurate readings in harsh chemical environments, resulting in unstable process control and potential safety hazards.

Large-diameter electromagnetic flowmeters are essential precision measuring instruments specially designed for industrial large-caliber pipeline fluid monitoring, which are widely applied in municipal water engineering, hydraulic engineering, and heavy industrial fluid transportation. Based on Faraday’s law of electromagnetic induction, the equipment converts the flow velocity of conductive fluids into measurable electrical signals to achieve real-time, high-precision flow metering.

The electromagnetic vortex turbine flow meter is an innovative integrated flow measurement device that combines the technical advantages of electromagnetic, vortex, and turbine flow meters. It effectively compensates for the single-measurement limitations of traditional flow meters and achieves high-precision and high-stability flow detection for diverse fluid media including liquids, gases, and steam.

The metallurgical heavy industry involves high-temperature, high-pressure, dusty, and strongly corrosive working environments, where pressure parameters of smelting furnaces, rolling equipment, and conveying pipelines are core indicators for judging production stability and equipment safety.
