.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)�
window mode
The change of state occurs when any thres-
hold is 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.
