The problem of determining the height of the center line of the submersible pump impeller from the liquid surface

How far is the distance between the pool liquid level and the center line of the submersible pump impeller that the submersible pump can operate normally for a long time? Is there a limit value? Can the liquid level be lower than the impeller? (Some manufacturers say it is possible) If you need to set high and low liquid level alarms to start and stop the pump in the pool, how to determine the value (mainly the determination of the low liquid level value), thank you for your help.

The suction liquid level of the submersible pump mainly depends on the length of the suction pipe of the submersible pump. Some submersible pumps also have a section of suction pipe at the inlet, so the liquid level can be lower than the center line of the impeller.
