为了满足石油产品计量自动化的需要,我局干一九七七年研制成功了油罐计量仪标准器。它具有精度高、计量性能稳定、结构简单、便于携带等优点,可以作为检定称重式油罐计量仪的标准器使用。随着“称重法油罐计量系统”的广泛普及,LY2-2型油罐计量仪标准器必将在更多的单位使用。现对这种仪器的结构原理作一简要介绍。一、技术要求和指标 LY2-2型油罐计量仪标准器主要用以检定、校准称重式油罐计量仪,对其砝码进行重
In order to meet the need of automation of petroleum products measurement, our bureau successfully developed the gauge of tank gauges in 1977. It has the advantages of high accuracy, stable metrology performance, simple structure, easy to carry, etc. It can be used as a standard instrument for checking weighing tank gauging instrument. With the “Weighing Acting tank metering system,” the widespread, LY2-2 tank gauge standard will be used in more units. Now the principle of the structure of this instrument make a brief introduction. First, the technical requirements and indicators LY2-2-type tank gauging instrument is mainly used to test verification, calibration weighing tank gauges, their weights were heavy
