Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents" Drafting is required. Please note that some of the contents of this document may involve patents. The issuing organization of this document does not assume the responsibility for identifying patents. This document is proposed and coordinated by the National Technical Committee for Standardization of Petroleum Products and Lubricants (SAC/TC 280). This document was drafted by. Sinopec Petrochemical Research Institute Co., Ltd., Sinopec Sales Co., Ltd. Zhejiang Petroleum Branch Sinopec Zhenhai Refining and Chemical Company, China Certification and Inspection Group Shandong Co., Ltd., Qingdao Aobang Measuring Instrument Co., Ltd. Responsible Company, Beijing Junyou Xinye Technology Co., Ltd., and Beijing Ruisai Great Wall Aviation Measurement and Control Technology Co., Ltd. The main drafters of this document are Wei Jinxiang, Sun Yan, Cao Lei, Teng Zhifang, Liu Chongwei, Zhang Shanyou, Fan Mingjun and Zhang Jinguang. The density of petroleum and liquid petroleum products in the tank is directly Measurement by resonant cylinder density meter method

1 Scope

This document specifies the general requirements for accuracy, measurement conditions and measurement methods for direct measurement of the density of oil in tanks by resonant cylinder densitometers. The requirements are specified in the following two types of equipment. portable electronic density meter and tank automatic density meter. Inspection method. This document is applicable to single-phase liquid petroleum and its products with a reid vapor pressure of less than 100 kPa in atmospheric tanks and sufficient fluidity, and other Similar products that meet the requirements shall be implemented accordingly. This document applies to measuring density in inventory and transfer measurements. This document is not applicable to density measurements in pressurized tanks or refrigerated tanks. Note 1.For multifunctional electronic metering devices capable of measuring density, when based on the same principle as a resonant cylinder densitometer, the density measuring part is equivalent to the resonant cylinder Density meter. Note 2.Resonance cylinder densitometers are generally suitable for low-viscosity liquid petroleum products without wax. For viscous liquid crude oil and petroleum products, such as crude oil, lubricating oil, and residual fuel oil, etc., may be difficult to use. Manufacturers usually give the maximum viscosity of the applicable liquid in the instruction manual.
