A "Hydrogen Dispenser Breakaway Coupling" is a safety device used in hydrogen refueling stations to prevent accidents and leaks during the refueling process. It is designed to disconnect and seal the hydrogen fueling hose from the dispenser in the event of an unintended drive-away, over-pressure situation, or other emergency scenarios. This helps to ensure the safety of both the refueling station personnel and the vehicle being refueled.
Product Description
It can be still used after being reassembled once being broken away, making the maintenance cost low.

TECHNOLOGY ADVANTAGE
A. The optimal vibration mode of flowmeters is determined after the finitement analysis, the structure is improved and the modal in each order is reasonably distributed. Driven by the simple harmonic, each position of the measuring tube will respond. A reasonable damped structure has been designed to improve the noise-proof feature.
B. The high-performance 32/40-bit DSPs are used as the core processor, including high efficiency instruction set, hardware FFT and other peripherals specially used for audio signal processing to fast process various digital signals in real time and largely improve the stability of flowmeters
C. The mass flowmeter is welded by the unique vacuum brass solder process, which ensures the welding quality and also fully guarantees the stress removal to largely improve the zero stability of mass flowmeter in use.
D. Water gauge calibration testing platform: The Company owns the scarce calibration systems and stability testing system for water gauges with large-span diameter (DN6-DN400) in the industry for the operating condition calibration and the stability testing of flowmeters.
E. High pressure gas testing platform: The Company has established the first high pressure air (25MPa) calibration system and stability testing system in China for the operating condition calibration and the stability testing of high-pressure flowmeters.
F. Liquid nitrogen low-temperature calibration testing platform: The Company has established the first copious cooling calibration system and stability testing system in China for the operating condition calibration and the stability testing of low-temperature flowmeters.
