Creep flow suppression

Flattens the output signal
after root extraction at
small differential pressures
(around zero).

Functionalities:
None
(function is deactivated)
Step
(the
parameter ‘creep flow
threshold
’ defines the
range around zero. Within
this range, the displayed
value and the output signal
are set to zero,
see Figure
15 . Is mostly used when
the volume flow is
subsequently added up.)
Linear
(the
parameter ‘creep flow
threshold’ defines the
range around zero. Within
this range, the square
rooted characteristic line is
replaced by a linear one =>
increase around zero is
limited,
see Figure 16 .
Mostly used for
downstream controls.)
