Instrumentation for safe and efficient hydrogen compression and transport

Hydrogen can permeate through many metals, including those used in pressure sensor diaphragms and seals. This can lead to hydrogen-induced cracking, reduced mechanical strength and eventual sensor failure. Endress+Hauser offers pressure sensors with specialized diaphragm materials and plating designed to resist hydrogen permeation and maintain long-term stability in hydrogen-rich environments.

• Reliable measurement and high accuracy in hydrogen applications.
• Complete portfolio of pressure transmitters available with gold-plating option.
• Bluetooth connection for convenient access to the device.

Hydrogen is the lightest gas that exists and at atmospheric conditions it has a density that is 10 times lower than natural gas. Since hydrogen streams have little mass to propagate sound and often exhibit high gas velocities, velocity-based measurement principles struggle to produce repeatable and accurate flow measurement results. Our Coriolis flow meters offer:

• Best-in-class turndown for hydrogen flow measurement, gasket-free construction, SIL and Ex for highest safety.
• Highest measurement sensitivity to achieve the widest mass flow measurement range.
• Superior zero-point stability, can measure hydrogen at low pressure with the lowest measurement error in the market.

Capacitance technology offers reliable measurement for liquid hydrogen applications, unaffected by dielectric constant, vapors, temperature, or pressure changes, ensuring safe and accurate level measurement. Our Liquicap FMI51 offers:

• Enhanced safety through proven capacitance technology.
• Special insulation components and separate electronics make sure the cryogenic temperatures do not harm the devices.
• Proven in use and suitable for use in small stationary process tank.
