Constant level
This control mode requires an external level sensor.
The pump can control the level in a tank in two ways
(see the figure above):
• As an emptying function where the pump draws
the liquid from the tank.
• As a filling function where the pump pumps the
liquid into the tank.
The type of level control function depends on the
setting of the built-in controller.
Example:
• One external level sensor with emptying function.
