Inlet and outlet sections are to be provided when the flow sensor is
installed within a piping system. These provide compensation for
disturbance due to curvatures, valves, pumps, reducers and the
like.
Shut-off and control devices should never be positioned directly
ahead of the flow sensor.
Before installing the flow sensor, the flow direction at the installa-
tion point must be determined. The flow direction through the flow
sensor is marked on the type plate. The flow direction is defined as
follows:
Flow direction positive
from
–
to
+
Flow direction negative
from
+
to
–
Change of flow direction
If the flow direction changes due to the system, the flow
sensor does not have to be dismantled.
Only the signs for the KA parameters in the control soft-
ware have to be changed.
Always bear the following in mind when choosing the installation
position of the flow sensor:
