Title:
LIQUID INSPECTION EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2008/075511
Kind Code:
A1
Abstract:
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.
