标准金属量器

标准金属量器是对液体和气体体积数量进行准确测量的计量器具，主要由计量颈、液位管、计量颈标尺、上锥体、圆筒体、下锥体、阀门、支架和调平螺栓等组成。按其准确度等级可分为一等、二等及三等。工作原理：采用容量比较法，直接或组合得到需要检测的容积值。它可以通过一等金属量器标准装置直接传递到下一级计量标准和工作量器，还可以为流量类等其它计量提供容量溯源单位。工作特点：操作方便，计量准确度高。技术依据：JJG259－2005《标准金属量器检定规程》。The standard metal volumetric prover is a metrological instrument used for accurate measurement of liquid and gas volume quantities. It mainly comprises a metrological neck, liquid level tube, metrological neck scale, upper cone, cylindrical barrel, lower cone, valve, support, leveling bolt, and other components. It is categorized into first-class, second-class, and third-class based on its accuracy grade. Operating Principle: It adopts the volume comparison method to obtain the volume values to be detected either directly or through combination. It can directly transfer metrological values to next-level metrological standards and working volumetric provers via the first-class standard metal volumetric prover device, and also provide capacity traceability units for other metrological applications such as flow measurement. Operating Characteristics: It features convenient operation and high metrological accuracy. Technical Basis: JJG 259-2005 Verification Regulation for Standard Metal Volumetric Provers
