System und Verfahren zur Volumenbestimmung von Körpern oder Stoffen aus dielektrischem und/oder leitfähigem Material

The invention relates to a system (100) for measuring filling material within a first measuring cell (400A) and a second measuring cell (400B), the first and second measuring cells (400A, 400B) having interiors delimited from one another. For the purpose of measurement within the first measuring cell, the system comprises a first antenna (202) for emitting a transmission signal (702, 704) into the interior of the first measuring cell, the first antenna being designed as an electrically short antenna having an at least substantially hemispherical radiation characteristic and comprising a disk-shaped carrier substrate (205), a first sensor (200) for receiving a time-of-flight-based radiation signal (703, 705) and an evaluation module (201) for evaluating the received time-of-flight-based radiation signal. For the purpose of measurement within the second measuring cell, the system comprises a second sensor (300) for receiving a measurement signal relating to a filling level and/or a volume within the interior of the second measuring cell, which signal is able to be evaluated by an evaluation module (201, 301) of the system. The system is configured, for the purpose of determining the volume of bodies or substances (500, 502, 503, 504) composed of dielectric and/or conductive material within the interior of the first measuring cell, to put both evaluated signals jointly in a functional relationship with an adjustable reference volume of bodies or substances within the interior of the first measuring cell. The invention furthermore relates to a method which can be carried out by means of the system.
