    • A liquid measuring device and an automatic analyzer which employs a resonance phenomenon of sound waves to detect an amount of a liquid reserved in a vessel with an opening are provided. The liquid measuring device includes a sound source that emits sound waves toward the opening, a control device that controls a frequency of the sound waves emitted by the sound source, a wave receiver that measures a resonance generated as the sound waves emitted by the sound source causes an air column in the vessel to resonate, a detector that detects a resonance frequency of the resonance measured by the wave receiver, and a liquid-amount determination unit that determines, based on the detected resonance frequency, an amount of the liquid reserved in the vessel.
    • 提供一种使用声波的共振现象来检测在具有开口的容器中保留的液体的量的液体测量装置和自动分析器。 液体测量装置包括朝向开口发出声波的声源,控制由声源发出的声波的频率的控制装置,测量由声源发出的声波产生的共振的波接收器 导致容器中的空气柱谐振,检测由接收器测量的共振的共振频率的检测器和液体量确定单元,该液量确定单元基于检测到的共振频率来确定保留的液体的量 船只。
