Switching behaviour (N/O or N/C contact) and hysteresis are adjustable.
N/O contact: XXX- value > YYY- value N/C contact: XXX- value < YYY- value
Switch closes when flow
exceeds XXX value
Switch opens when flow
exceeds YYY value
Example 1: XXX = 55% Example 2: XXX = 45%
YYY = 45% YYY = 55%
hysteresis = 10% hysteresis = 10%
