Hysteresis mode
The output switches when a threshold is reached:
•
When the flow rate increases, the output status changes when the high threshold X+ is
reached.
•
When the flow rate decreases, the output status changes when the low threshold X- is
reached.

X- = Low switching threshold of the transistor or the relay (1-, 2- or 3-)
X+ = High switching threshold of the transistor or the relay (1+, 2+ or 3+)

The status changes as soon as any threshold (X- or X+) is reached.
