Description of device functions
Proline Prosonic Flow 91
86
Hauser
VALUE 20 mA
Use this function to assign the 20 mA current a full scale value. Positive and negative
values are permissible. The required measuring range is defined by defining the VALUE
20 mA .
In the SYMMETRY measuring mode
106, the value assigned applies to both flow
directions; in the STANDARD measuring mode it applies only to the flow direction
selected.
User input
:
5-digit floating-point number, with sign
Factory setting
:
Depends on nominal diameter and country, [value] / / [dm
3
to m
3
or US-gal to US-Mgal]
Corresponds to the factory setting for the full scale value
!
Note!
• The appropriate unit is taken from the SYSTEM UNITS group
• The value for 4 mA always corresponds to the zero flow (0 [unit]).
This value is fixed and cannot be edited.
TIME CONSTANT
Use this function to enter a time constant defining how the current output signal reacts to
severely fluctuating measured variables, either very quickly (enter a low time constant) or
with damping (enter a high time constant).
User input
:
Fixed point number 0.01 to 100.00 s
Factory setting
:
1.00 s
