15.4.9 Enabling the cut-off function of the volume flow rate
If the absolute (and possibly damped, see chapter 15.4.2) measured volume flow rate is less than the cut-off
value plus an hysteresis value, the volume flow rate value is set to 0:
• the display then shows a volume flow rate = 0.
• the outputs and the totalizers react as if the actual volume flow rate were equal to 0.
