Caution!
For flow measurements in vertical pipes, the primary device should be mounted at a position with
upward flow. This prevents partial emptying of the pipe during measurement.
3.4 Mounting position for gas applications
With gas applications, the transmitter must be mounted above the pipe. All impulse pipes must be
installed with a slope of at least 1:15 to the process connection - coming from the transmitter. This
ensures that any condensate flows back into the process pipe and thus does not influence the
measurement.
!
Note!
When measuring in humid gases, installation of condensate separators (5) and drain valves (6) is
useful for capturing and removing condensate.
