9. Asymetric mounting (temperature sensor)
The meter can be mounted asymetric, too. This means one tempera-
ture sensor is directly immersed in the volume measuring tube, where-
as the other temperature sensor is mounted in a protection pocket. For
the lower value of the temperature difference is then 5 K valid at the
respective lower flow limit qi. At this kind of installation the mentioned
protection pockets must be used.
Furthermore the national regulations of the respective country have to
be observered.
