13.5.6 "Constant level"
The pump maintains a constant level, independently
of the flow rate. See fig. 36.
Fig. 36 "Constant level"
This control mode requires a level sensor.
The pump can control the level in a tank in two ways:
• As an emptying function where the pump draws
the liquid from a feed tank.
• As a filling function where the pump pumps the
liquid into a storage tank.
See fig. 37.
The type of level control function depends on the
setting of the built-in controller. See section
13.12 "Controller" (Controller settings).
