発明の名称 (英語) HELMHOLTZ RESONANCE CONTAINER FOR VOLUME MEASUREMENT, VOLUME MEASUREMENT DEVICE, AND VOLUME MEASUREMENT METHOD 新技術説明会
発明の概要(英語) A Helmholtz resonance container (110) for enabling the volume of an object to be measured in a noncontact manner using Helmholtz resonance in a liquid comprises: a container (130) having a sealable opening (132); a neck (138) having a lower end communicating with a hollow portion inside the container (130) and an open upper end; and a cover member (140) provided at the upper end of the neck (138) and having an opening communicating with the inside of the neck (138). An edge of the opening (112) of the cover member (140) forms a reed (152) for generating sound and becomes thinner as approaching the opening. Sound is generated by the reed (152) by hitting a water current against the reed (152) from a water pipe (118), and in response to this sound, Helmholtz resonance is generated in the container (110). The volume of the object can be measured by a predetermined functional relation by putting the object in the container (130) and checking the peak frequency of the Helmholtz resonance.
