Installation
Capacitive level measurement principle: probe line and conductive liquid constituted the
capacitor, among them the metal inner core of probe line is one pole of capacitor the other pole is conductive liquid, the material between them is high stability PPR or gather fluorine ethylene.The probe line insulators outer as media of capacitor poles, the space which surrounden by liquid is changedalong with the liquid level changing, so that make relative space of capacitor polar changed which leading to the changed of capacitance. According to the capacitance formula we can find out the relationship between liquid height and capacitance.
Features
