标准体积管系指管式流量校验装置。是一种容积基准器。用它来校验能发出计数脉冲的速度式流量计和各种容积式流量计。在石油开发、炼油、油港及流量仪表科研单位广泛使用,也用于化工部门在腐蚀性介质中工作的流量计的校验。为了进一步提高产品使用精度和使用寿命,各用户对体积管的内防腐质量提出了更严格的要求。如某炼厂使用的一台体积管,由于体积管内防腐采用溶剂型涂层,只用了一年多
Standard volume tube refers to the tube flow calibration device. Is a volume base. Use it to verify the speed meter and various volumetric flow meters that issue count pulses. In the oil development, oil refining, oil and gas meters scientific research units widely used, but also for the chemical industry in corrosive media flow meter calibration. In order to further improve product accuracy and service life, all users of the volume of the tube within the anti-corrosion quality made more stringent requirements. For example, a volumetric tube used in a refinery uses a solvent-based coating for corrosion protection in a volumetric tube and only takes more than a year
