Abstract: A liquid tank device comprises a tank housing for storing a liquid within a tank volume inside of the tank housing, whereby the tank housing comprises at least one conduit opening that can be connected in a liquid-tight manner to at least one conduit for the liquid such that the liquid can be supplied to or removed from the tank volume within the tank housing through the conduit opening. A method for warning of and avoiding critical operating conditions of a liquid tank device comprises the detection of a tilting of the tank housing by means of a tilt detection device. The tank volume is shut off from the at least one conduit by means of a closing device if a tilt information from the tilt detection device exceeds a preset tilt value, resulting in avoiding further flow of liquid into or from the tank volume through the at least one conduit after detecting the tilting of the tank housing.

Abstract: A cartridge for handling a fluid comprises a housing comprising an impermeable shell in which at least one port for the fluid is formed. The housing includes a cartridge head including at least one of the ports. The cartridge head is arranged for coupling to a head part to place those of the ports present in the cartridge head in sealed fluid communication with ports of the head part. The cartridge includes a transponder, including at least a wireless transceiver and a data processing device for processing data exchanged via the wireless transceiver. The transponder is arranged in at least one of a recess in the shell and a recess in a shielding part joined to the shell. The transponder is arranged between an exterior surface of the shell and the shielding part.
