A Noflote System detects the electrical resistance between a Noflote electrode and an earth electrode. The earth reference connected to the controller may be the walls of a metal vessel, pipework within the vessel, the earth rod of a multiple sensor or another Noflote electrode.

When the liquid rises to touch the Noflote electrode an internal relay energises (or de-energises) to operate an alarm, pump, etc. Complex processes can be controlled automatically by means of two or more Noflote systems.
