Function description SYSTEM PARAMETER
INSTALLATION
DIRECTION SENSOR
Use this function to reverse the sign of the flow quantity, if necessary.
Options:
NORMAL (flow as indicated by the arrow)
INVERSE (flow opposite to direction indicated by the arrow)
Factory setting:
NORMAL
! Note!
Ascertain the actual direction of fluid flow with reference to the direction
indicated by the arrow on the sensor (nameplate).
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 totalled, (positive
or negative full scale value
➁ = 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”
➂ (e.g. backflow) corresponds to the mirrored VALUE
20mA
➁ (e.g. flow).
Positive and negative flow components are taken into account.
Example for current output:
! Note!
The direction of flow can be output via the configurable status output.
