摘要

A device for detecting a discrete level in a storage container for liquids, in particular in a pressurized water container of a plant for the properties of the water supply, with a storage container (500) and abuts against a pressure of an air cushion (38) between a minimum filling level (11) and a maximum filling level (hl) which, by means of a supply line (20) supplied liquid (w2) stores and this, if required, in a supply line (24), with a on a cylindrical surface of the container (13) of the storage container (500) between a lower connection for water level indicator (5a) and an upper connection for water level indicator (5b) arranged water state display device (32), which consists of a in the lower connection (5a) arranged lower water state fitting (32.1) and a in the upper connection (5b) disposed upper water state fitting (32.2) with an interposed display tube (32.3), via which the filling level (l) is imaged,characterized by the,• that on the display tube (32.3) from the outside in a lower sensor (32.5) for detecting the minimum level (11) and optionally an upper sensor (32.6) for detecting the maximum filling level (hl) are arranged,• in that the sensors (32.5, 32.6) with a control unit (400) are connected, and• in that the sensors (32.5, 32.6) of the suitability, physical changes in the display tube (32.3) to determine if on the respective location of the sensor (32.5, 32.6) the liquid (w2) in the display tube (32.3) is present or not present.
