LIQUID INSPECTION EQUIPMENT

摘要

Liquid inspection equipment which can judge whether dangerous liquid such as gasoline is filling a container or not even in the case of a thick-wall container and can distinguish liquid explosive substance and acid/alkali liquid accurately. The liquid inspection equipment (10) comprises a weight sensor (14) and a dielectric constant sensor (15) for measuring the weight and the dielectric constant of a container (12) filled with liquid (13), respectively, a database (18) recording the judgment reference weight and the judgment reference dielectric constant for each type of container (12), and a liquid judgment section (24) to which the judgment reference weight and the judgment reference dielectric constant, and measured weight and measured dielectric constant are inputted. The liquid judgment section (24) evaluates whether the measured weight and the measured dielectric constant satisfy the judgment reference weight and the judgment reference dielectric constant or not. If they do not satisfy, the liquid (13) is judged as a dangerous substance and an alarm (16) is actuated.
