.6 Possible switching modes of the 8032
hysteresis mode
The change of state occurs when a threshold is detected
(increasing flow rate: high threshold (OHI) to be detected,
decreasing flow rate: low threshold (OLO) to be detected).

the delay (del) is set for the both switching
thresholds. the switching only occurs when
either threshold value (ohi - olo) is excee-
ded for a duration higher than the del delay.
