The float's magnetic system in the guide tube actuates a resistance measuring chain that corresponds to a 3-wire potentiometer circuit. The measurement voltage generated by this is proportional to the fill level.
The measurement voltage is very finely-stepped due to the contact separation of the measuring chain and is thus virtually continuous. Depending on the requirements several different contact separations are available.
