As the float follows the level of liquid in the vessel, the magnet also moves up and down. The magnet activates the reed switch when they're both at the same level, providing an "on" or "off" signal.

Magnetic float liquid level switches power precision in process industries, with market growth projected from $1.7B in 2024 to $3.2B by 2035 at 6.3% CAGR.

A small DAS PCB directly attached to the pressure sensor provides dynamic control of liquid level measurements. It generates control signals from the PC-based control-and-dispense GUI to activate the ...
