Adjustment and functions
Hysteresis operation
The change of state is done when a threshold is detected
(increasing flow rate:high threshold (OHI) to be detected,
decreasing flow rate: low threshold (OLO) to be detected).

Fig. 32 : Window operation of the transistor output
The time delay (DEL) is valid for both output thresholds. switching
is only done if one of the thresholds (OHI - OLO) is exceeded for a
duration longer than this time delay.
