1.3.6.1
The TME 400 can be used in hydrogen-containing natural gas up to pure hydrogen.
There are no safety-related concerns for this use.
Notice
In accordance with the German TR-G19 – the TME 400 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.
