The human influence on the global climate has become increasingly obvious, for which the high energy needs of modern societies play a significant role. To counteract this development, environmentally friendly technologies must become more suitable for everyday use. Hydrogen, with its high efficiency but minimal impact on the environment, is the ideal ecological alternative to achieve this goal and is destined to play a special role in replacing fossil fuels energy fossil fuel energy sources.

Heinrichs has played an active role in the high-pressure hydrogen sector providing H2 vehicle dispenser measuring solutions for more than 10 years.

To achieve the necessary high energy density with elemental Hydrogen, the lightest of all elements, an appropriate compression is required. Pressures greater than 1000 bar as well the high permeability of hydrogen therefore pose the greatest technical challenges for the technology. Driven by our gained experience, the requirements of modern applications and the latest technological advances, Heinrichs has developed the new TMU-W product range, with a Coriolis architecture specially designed for high-pressure Hydrogen applications.

For the development of the TMU-W the latest techniques in the simulation of structure and flow conditions were applied:

• CSM (Computational Structural Mechanics)
• FEM (Finite Element Method)
• CFD (Computational Fluid Dynamics)
• CEM (Computational Electromagnetics)
• FSI (Fluid Structure Interaction)
• TFSI (Thermal Fluid Structural Interaction)

These techniques allow a precise virtual assessment of complex, coupled behaviours meaning the specific characteristics of H2 high pressure measurement can be addressed directly. The result was the rapid development of an optimised Coriolis sensor.
