Reliable Level Measurement Technologies Empower the Future of Hydrogen Energy
Reliable Level Measurement for a Green Hydrogen Economy
Hydrogen is becoming a cornerstone in the transition to a greener and more sustainable global economy. With growing investments and rapid technological advancements worldwide, the safe and efficient handling of hydrogen is now more crucial than ever. Whether it’s in chemical manufacturing, steel production, or future clean transportation systems, reliable level measurement plays a vital role. Jiwei Automations, a leading manufacturer of level measurement instruments in China, provides cutting-edge solutions such as radar level meters and liquid level switches tailored for demanding hydrogen applications.
Why Hydrogen Needs Precision Level Measurement
Hydrogen is a highly valuable energy carrier. Especially when generated from renewable sources like wind or solar power, it becomes “green hydrogen” — offering a carbon-neutral cycle from production to usage. However, producing green hydrogen is still relatively expensive. Any inefficiency, leakage, or incorrect level detection during its production, transport, or storage can result in significant energy losses and safety hazards. This is where Jiwei’s radar level meters and level switches become essential tools to optimize hydrogen processes.
Where Jiwei Instruments Make a Difference in Hydrogen Applications
One key application of Jiwei’s measurement instruments is within alkaline electrolysers, which are commonly used to generate hydrogen. In these systems, precise level monitoring of electrolyte tanks, water in-feed lines, and intermediate hydrogen gas storage is critical.
Jiwei’s JWrada® series radar level meters, operating at 80 GHz, are particularly suited for such tasks. These non-contact sensors can handle low-dielectric media, deal effectively with steam and foam interference, and provide stable echo signals even in harsh gas environments. Thanks to their advanced signal processing algorithms, they deliver reliable level readings even under fluctuating temperature or chemical conditions.
Meanwhile, Jiwei’s Ring-11 liquid level switches offer robust point-level detection for liquids used in the hydrogen production process. These tuning fork switches are vibration-based, offering high immunity to turbulence, condensation, and low-density media — a crucial factor for detecting water or caustic solutions like potassium hydroxide in electrolyser systems.
Engineered for Harsh Environments and Safety
The hydrogen industry poses unique technical challenges: media with low dielectric constants, corrosive alkaline solutions, and demanding hygienic or explosion-proof environments. Jiwei’s tuning fork level instruments are built with 316L stainless steel, available with PTFE coatings, and designed to meet strict Ex explosion-proof and SIL2/SIL3 functional safety certifications. These features make them highly durable and suitable for long-term deployment in hydrogen applications.
Supporting the Growth of Hydrogen Infrastructure
Hydrogen is already widely used in the chemical and steel sectors, and it’s quickly gaining ground in transportation, power generation, and clean fuels. Many companies are now investing in their own small-scale electrolyser systems as a starting point. At the same time, countries around the world are launching national subsidy programs to accelerate hydrogen development.
As hydrogen continues to expand into sectors like long-haul trucking, green shipping, and off-grid energy systems, the need for reliable, precise, and safe level measurement instruments will only increase. Jiwei is ready to support these developments with innovative, field-proven technology.
Looking Ahead: Jiwei’s Commitment to Hydrogen Solutions
Mr. Xie, Chief Engineer of Jiwei Automations
With the global hydrogen economy evolving rapidly, questions remain about how hydrogen will be stored, transported, and integrated into new systems. Will it be delivered as liquid hydrogen or as a derivative like ammonia or methanol? Regardless of how the supply chains shape up, one thing is clear: accurate level measurement will remain a foundational component of hydrogen safety and efficiency.
Jiwei Automations is committed to advancing the hydrogen industry with reliable radar level meters and liquid level switches, ensuring every drop of energy is measured, monitored, and protected.
