corresponding loads acting on the connecting pieces. For these
totals, neither the direction of the loads nor their distribution is taken
into consideration.
The selectable control modes are:
Δp-c:
The electronics keep the differential pressure created by the pump
above the permitted feed flow range constantly at the pre-selected
differential pressure setpoint H
(Fig. 10).
Q = Volume flow
H = Differential pressure (min./max.)
