Abstract
Devices and corresponding methods for capacitive foam detection in liquid containers are disclosed. The device has a sensor with a measurement electrode having a plurality of sub-electrodes, a bottom plate that is used as a counter electrode for arranging a liquid container, a sensor electronic unit that is connected to the measurement electrode and the bottom plate and is adapted to determine an impedance, in particular a capacitance, between the measurement electrode and the bottom plate, and an evaluation unit, the measurement electrode being arranged substantially perpendicularly to the bottom plate.
