About capacitance level measurement

Capacitance level measurement with Liquicap is a simple and cost-effective solution which offers a wealth of possibilities for level monitoring in liquids. Particularly in small tanks and build-up forming media. Point level detection works with Liquicap, Liquipoint, Minicap or Solicap capacitance level switches also in applications involving aggressive media and heavy build-up in liquids and solids. Check out the broad range of capacitance level sensors and click on the button below.

Capacitance level sensors are a proved, as well as cost-effective solution for level measurement and point level detection in liquids and bulk solids. Various transmitters for continuous level measurement and switches for point level detection are available. The measurement of interface is also possible. The measuring principle is proven in millions of applications.

Capacitance measurement: Measuring Principle

The principle of capacitive level measurement is based on the capacitance change of a capacitor. The probe and the tank wall form a capacitor whose capacitance is dependent on the amount of product in the tank: An empty tank has a lower, a filled tank a higher capacitance.
