Title: Ion exchanger regenerating salt level check - by light or sound waves reflection or absorption
Inventor: JOSTAN JOSEF DIPL CHEM DR RER
IPC: B01J49/75
Filed: 1979-03-23
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.
