石油和液體石油產(chǎn)品罐內(nèi)密度直接

測(cè)量諧振筒密度計(jì)法

1范圍

本文件規(guī)定了通過諧振筒密度計(jì)直接測(cè)量罐內(nèi)油品密度對(duì)準(zhǔn)確度、測(cè)量條件和測(cè)量方法的一般要

求，并按便攜式電子密度計(jì)和油罐自動(dòng)密度計(jì)兩種設(shè)備形式規(guī)定了測(cè)量步驟和/或安裝要求以及校準(zhǔn)和

檢驗(yàn)方法。

本文件適用于常壓罐內(nèi)雷德蒸氣壓小于100kPa并具有足夠流動(dòng)性的單相液體石油及其產(chǎn)品，其他

符合要求的類似產(chǎn)品參照?qǐng)?zhí)行。

本文件適用于在庫(kù)存和交接計(jì)量中測(cè)量密度。

本文件不適用于在帶壓罐和冷凍罐內(nèi)測(cè)量密度。

注1：對(duì)可測(cè)量密度的多功能電子計(jì)量裝置，當(dāng)基于諧振筒密度計(jì)的相同原理時(shí)，密度測(cè)量部分等同于諧振筒

密度計(jì)。

注2：諧振筒密度計(jì)一般適用于未結(jié)蠟的低黏度液體石油產(chǎn)品，對(duì)于黏稠的液體原油和石油產(chǎn)品，如原油、潤(rùn)滑油

和殘?jiān)剂嫌偷?，可能難以使用。制造商通常在使用手冊(cè)上給出了其適用液體的最大黏度。

2規(guī)范性引用文件

下列文件中的內(nèi)容通過文中的規(guī)范性引用而構(gòu)成本文件必不可少的條款。其中，注日期的引用文

件，僅該日期對(duì)應(yīng)的版本適用于本文件；不注日期的引用文件，其最新版本（包括所有的修改單）適用

于本文件。
