Remark
:
•
Flow range for Air at 6 bar(g), 50 °C and 90% humidity.
•
The flow measurement range is related to the actual inner
diameter of the installed pipe. Differences in the inner diameter
will result in different maximum and minimum flow values. The
exact range can be calculated using Flow Range software, which
can be downloaded from
