MEASURING MODE
(Contd)
Pulse output
STANDARD
Only the flow components for positive flow direction are totalled. Components
in the opposite direction are not taken into account.
SYMMETRY
Positive and negative flow components are taken into account.
Status output
!
Note!
The information is only applicable if LIMIT VALUE was selected in the function
ASSIGN STATUS OUTPUT.
STANDARD
The status output signal switches at the defined switch points.
SYMMETRY
The status output signal switches at the defined switch points, irrespective of
the sign. In other words, if you define a switch point with a positive sign, the
status output signal switches as soon as the value is reached in the negative
direction (negative sign), (see illustration).
Example for the SYMMETRY measuring mode:
Switch-on point: Q = 4
Switch-off point: Q = 10
➀
= Status output switched on (conductive)
➁
= Status output switched off (not conductive)
Totalizer
STANDARD
Only positive flow components are totalled. Negative components are not
taken into account.
SYMMETRY
The positive and negative flow components are balanced. In other words, net
flow in the flow direction is registered.
