Abstract:
A system for electronically monitoring scaling in an apparatus for heating and/or evaporating a liquid, the system comprising an evaluation unit; and a container having a liquid inlet, an outlet, a heating element for evaporating liquid from the container, at least one liquid level sensor and at least one flow meter, the evaluation unit being connected to the at least one liquid level sensor, so that a value relating to a desired filling volume of the container can be inputted into the evaluation unit and/or can be stored therein and a desired liquid level for the desired filling volume can be compared to a nominal liquid level in the evaluation unit when water is constantly added by the at least one flow meter, whereby the nominal liquid level is detected by the at least one liquid level sensor, or a nominal filled-in volume is detected by the at least one flow meter, when the liquid level sensor senses the desired liquid level and a signal is sent by the evaluation unit, such that said signal is a measure of an absolute nominal liquid level, an absolute nominal filled-in volume, and the nominal liquid level with respect to the desired filling volume and/or the nominal filled-in volume relating to the desired liquid level.
