Notice
In general, only the horizontal installation of the USM GT400 is strongly
recommended. Turning the meter by more than 2 flange holes should not be
used to avoid the collection of condensates in the sensor pockets. Only in dry
and clean gas, other installation positions might be possible also, but it is not
recommendable.
