Out-put signal can be controlled by its float and float movements change its analog out-put signals. AU-21 works according to physical principles that are buoyancy force, pull and push force of electromagnetic.

Changing of the liquid level causes vertical movement to float. Magnets which are fixed to the float affect the switches and produce signal according to switches on/off positions.
This type of level controllers have 2 different reed switches, every switch can control its contacts.
