Application

The TMU-W product line was specially developed for hydrogen filling applications for dispensing stations. During the fueling process, extremely high zero-point and long-term stability are required. Its special design provides the highest possible stability and unrivaled measuring accuracy to the user. Special materials and sophisticated engineering design methods like FEM, CFD, FSI and others were used to fulfill this task.
