Process data
Measuring task:
Level measurement
Measuring point:
Tank
Measuring range up to:
15 m
Medium:
Liquid hydrogen
Process temperature:
-253 ... -251 °C
Process pressure:
0 ... +1 bar
Special challenges:
Low density, low dielectric constant, outgassing of the medium
Application
If energy-rich hydrogen has to be transported over long distances, special tanker ships are used. To minimise losses, the hydrogen is cooled down to -253 °C at 1 bar pressure so that it can be stored in liquid form. The level can be measured either by means of thin impulse lines and conventional differential pressure or free-radiating radar. An elaborate standpipe, which would also lead to increased heat input, is not required.
Your benefit
Reliable
Highly accurate measurement of even low-density materials
