1.3.5.1. Suitability and safety for natural gas containing H2
The TME400 can be used in hydrogen-containing natural gas. There are no safety-
related concerns for this use.
In accordance with the German TR-G19 – the TME400 is suitable and ap-
proved for use in custody transfer applications – in natural gases with a
maximum hydrogen content of 10 mol-%, with the accuracy specified in
chapter 1.4.2.9 Measuring accuracy.
Since there are currently no certified test rigs in Germany to calibrate meters with
higher hydrogen-containing gases, an accuracy above 10 mol-% cannot be tested or
certified.
Not custody transfer measurements are of course possible in natural gases with a hy-
drogen content above 10 mol%. However, a reduced measuring range must be taken
into account if applicable. Please contact RMG for further information.
