ISTALLATION
Use this function to reverse the sign of the flow quantity, if necessary.
DIRECTION SENSOR
Options:
FORWARDS (flow as indicated by the arrow)
BACKWARDS (flow opposite to direction indicated by the arrow)
Factory setting:
NORMAL
MEASURING MODE
Use this function to select the measuring mode for all outputs and for the internal totalizer.
Options:
STANDARD
SYMMETRY
Factory setting:
STANDARD
The responses of the individual outputs and the internal totalizer in each of the measuring
modes are described in detail on the following pages:
Current output
STANDARD
Only the flow components for the selected flow direction are output, (positive or negative
full scale value n = flow direction). Flow components in the opposite direction are not
taken into account (suppression).
Example for current output:
SYMMETRY
The output signals of the current output are independent of the direction of flow (absolute
amount of the measured variable). The "VALUE 20mA" o (e.g. backflow) corresponds to
the mirrored VALUE 20 mA n (e.g. flow). Positive and negative flow components are
taken into account.
Example for current output:
!
The direction of flow can be output via the configurable status output.
