The production of hydrogen has risen sharply in recent years and will continue to increase steadily.

Electrolysis plants are used to produce hydrogen, which are mainly powered by renewable energies such as wind turbines and solar energy.

After production, the hydrogen is mainly transported via pipelines, which requires very accurate flow measurements.

Due to the high accuracy required, conventional flow measurements such as turbine flowmeters or ultrasonic in-line flowmeters are used in most cases.

However, these have a major disadvantage, as the meters are constantly in contact with the aggressive hydrogen and additional pipe joints are created, which could lead to a possible leak.

In addition, these flowmeters have to be removed regularly for re-calibration.

The solution is a non-intrusive ultrasonic Clamp-on flowmeter.

In contrast to conventional flow measurement, the sensors of a clamp-on system are mounted on the outside of the pipe and never touch the medium. This eliminates the need to cut into existing pipe and ongoing processes don’t need to be interrupted either

In this presentation, the advantages of clamp-on system will be explained and various application examples with results will be shown.
