Abstract

The level of the salt in a storage container which is needed for the regeneration of an ion exchanger filling of a water softener for a dish washer or washing machine must be checked and replenished if required. The salt container is scanned by beams of light or sound. The light or sound waves are reflected by its contents and/or traverse it with a certain attenuation. A detector determines any deflection of the reflection or transmission level from a desired value and actuates a warning signal to indicate the necessity for replenishment.
