LJG-33型单向、无阀、一球式标准体积管式流量标准装置(以下简称标准体积管),已由开封仪表厂和胜利油田联合试制成功。这种标准体积管结构先进,设计合理。容积复现性为±0.0064％,达到了同类产品的国际先进水平。容易实现校验自动化,还可以在现场实液条件下对流量计进行检定,不存在被测介质挥发的问题;可以安全地测量挥发性、粘性和腐蚀性液体。还由于弹性球挤刷管壁,测量值不象标准量器那样受液体残留量的影响。所以,这种标准体积管可以广泛地应用在油港、油田等场合。一、主要技术参数标准管尺寸:φ219×8 标准体积段长度:42米标准管容积设计值:1350升。经标定,
LJG-33 one-way, valveless, a ball standard volume tube flow standard device (hereinafter referred to as the standard volume tube), Kaifeng Instrument Factory and Shengli Oilfield jointly trial success. This standard volume tube structure advanced, well-designed. Volume reproducibility of ± 0.0064%, reached the international advanced level of similar products. It is easy to automate calibration. It also verifies the flowmeter under the condition of on-site solid liquid. There is no problem of volatilization of the measured medium; it can safely measure volatile, viscous and corrosive liquids. Also due to the elastic ball squeeze tube wall, the measured value is not as measured by the liquid residual amount of standard equipment. Therefore, this standard volume tube can be widely used in oil ports, oil fields and other occasions. First, the main technical parameters Standard pipe size: φ219 × 8 standard volume segment length: 42 m standard tube volume design value: 1350 liters. After calibration,
