Transferability of calibration results obtained with conventional gases for application with hydrogen

Abstract

In the field of gas transport, the de-carbonisation of the energy supply is forcing the exchange of natural gas with hydrogen, either in mixtures or even pure hydrogen. Therefore, there is an increasing need to have reliable information about the behaviour of existing metering technologies with such hydrogen enriched gases or pure hydrogen. On the other hand, the availability of testing and calibration infrastructures for hydrogen has been very limited so far. A fast approach to close this gap is the usage of scaling procedures to transfer the calibration results gathered at facilities with conventional gases to field applications with hydrogen.The paper will introduce the scaling models applied at PTB for turbine gas meters (TM), rotary piston gas meters (RM) and differential pressure meters (DPM) to ensure transferability of calibration results obtained mainly with air and natural gas, and occasionally with nitrogen or water. All applied models are based on the Reynolds number as the dominant scaling parameter and include extensions to describe secondary effects if necessary.
