Process data
Measuring task:
Level measurement
Measuring point:
Tank
Measuring range up to:
2 m
Medium:
Liquid hydrogen
Process temperature:

Process pressure:
0 … +1 bar
Special challenges:
Measurement of gaseous hydrogen
Application
To store hydrogen with as little loss as possible, it must be cooled down to -253 °C at 1 bar so that it is in a liquid state. Liquid hydrogen is therefore stored in double-walled, insulated containers. In addition, the liquid hydrogen is overlaid with gaseous hydrogen. When liquid hydrogen leaves the insulated container, it evaporates immediately and heats up to room temperature. The level is measured reliably using the traditional differential pressure method.
Your benefit
Reliable
Highly accurate measurement of even low-density materials
Cost effective
Accurate measurement for optimal storage
User friendly
Installation in the double-walled container not necessary
