Abstract
An apparatus (14) for handling and/or measuring a liquid contained in a container (10) includes an elongate component (18) having a free end (20) and being insertable through a container opening (12) of the container (10) into the interior (22) of the container (10) with said free end (20) first and at least a part of an empty level indicator system (28, 30, 32) at the free end (20) of the elongate component (18). A transponder (28) for an RF-detection system (28, 30) of the empty level indicator system (28, 30, 32) is included for detecting an empty level of a liquid in at least one container (10).
Claims12
An apparatus for handling and/or measuring a liquid contained in a container, the apparatus comprising:
- an elongate component having a free end and being insertable through a container opening of the container into an interior of the container with said free end first;
- and
- at least a part of an empty level indicator system at the free end of the elongate component,
- wherein said part comprises at least one RFID tag for an RF-detection system of the empty level indicator system, wherein the elongate component comprises a suction lance for emptying the container via the container opening, the suction lance defining a central longitudinal axis extending through the free end, and wherein the at least one RFID tag is arranged in a suction area of the suction lance on a sieve at the free end of the suction lance such that the RFID tag intersects the central longitudinal axis and is arranged to be wetted by liquid when liquid is contained in the container.
An empty level indicator system for detecting an empty level of a liquid in at least one container, the empty level indicator system comprising:
- an elongate component having a free end and being insertable through a container opening of the container into an interior of the container;
- at least one RFID tag at the free end of the elongate component, wherein the at least one RFID tag is part of an RF-detection system;
- and
- an evaluation unit for detecting the presence of an empty level from a signal of the RF detection system,
- wherein the empty level indicator system comprises a reader corresponding to the at least one RFID tag, wherein the elongate component comprises a suction lance for emptying the container via the container opening, the suction lance defining a central longitudinal axis extending through the free end, and wherein the at least one RFID tag is arranged in a suction area of the suction lance on a sieve at the free end of the suction lance such that the RFID tag intersects the central longitudinal axis and is arranged to be wetted by liquid when liquid is contained in the container.
