原理与特点:基于阿基米德浮力原理,将浮子浸于被测液体中,体积一定的浮子所受的浮力转为电信号,再经数据处理,可直接显示密度值、温度值、标准密度值(20℃)及体积系数;操作简单,测量速度快;避免操作误差与读数误差,提高工作效率;具有存储、查询、外接打印等功能;便于功能扩展及网络化管理。检定执行JJG999-2005《称量式数显液体密度计国家计量检定规程》。用于石油产品的密度测量执行NB/SH/T0874-2013《原油和液体石油产品实验密度测定称量式数显液体密度计法》。
Principle and Features: Based on the principle of Archimedes buoyancy, floats immersed in the liquid to be measured, the buoyancy of a certain volume of float into electrical signals, and then processed by the data can be displayed directly on the density, temperature, standard density Value (20 ℃) and volume coefficient; simple operation, fast measurement speed; to avoid operational errors and reading errors, improve work efficiency; with storage, query, external print; easy to function expansion and network management. Verification implementation JJG999-2005 “Weighing digital liquid density meter national measurement verification procedures.” Density Measurement for Petroleum Products The NB / SH / T0874-2013 “Test Method for Density Determination of Crude Oil and Liquid Petroleum Products - Weighing Digital Liquid Density Meter” is adopted.
