Function description SYSTEM PARAMETER
INSTALLATION Use this function to reverse the sign of the measured variable, if necessary.
DIRECTION SENSOR
!
Ascertain the actual direction of fluid flow with reference to the direction indicated by
the arrow on the sensor (nameplate).
Options:
NORMAL (flow as indicated by the arrow)
INVERSE (flow opposite to direction indicated by the arrow)
Factory setting:
NORMAL
MEASURING MODE Use this function to define the measuring mode for all outputs.
Options:
STANDARD SYMMETRY
Factory setting:
STANDARD
The responses of the individual outputs in each of the measuring modes are described in
detail below:
Current and frequency output
STANDARD
The output signals of the current and frequency output are proportional to the measured
variable.
The flow components outside the scaled measuring range (between VALUE 0_4 mA or
VALUE F LOW m and VALUE 20 mA or VALUE F HIGH n), are not taken into account
for signal output but a message "CURRENT SPAN AT FULL SCALE VALUE" or
"FREQUENCY RANGE AT FULL SCALE VALUE" is issued.
Example for current output:
SYMMETRY
The output signals of the current and frequency output are independent of the direction
of flow (absolute amount of the measured variable).
The "VALUE 20 mA" or "VALUE F HIGH" o (e.g. backflow) corresponds to the
mirrored VALUE 20 mA or VALUE F HIGH n (e.g. flow).
Example for current output:
