Description
Select measured flow direction.
The flow meter will only output
current when flow value is meas‐
ured in selected direction.
Select current output scaling ac‐
cording to desired measurement
range and fail-safe mode.
Assign process value to the up‐
per output current (20mA)
Assign process value to the low‐
er output current
Fail-safe becomes active if ei‐
ther the selected process value
is unreliable, or the device
shows "Maintenance alarm".
Set filter time constant. Defines
the damping of the current out‐
put signal.
Select current output reaction in
case of a fault.
Define fail-safe current output
value if 'Fail-safe behaviour' pa‐
rameter is set to 'Fail-safe value'.
Minimum time the output stays
in fail-safe mode. Short events
will be prolonged.
