密度计

Based on the principal investigation of spinner flowmeter, water cut tool and densimeter, it is pointed out that production logging data is strongly dependent upon the changes of flow pattern and flowrate in muttiphase flow.

文章剖析了在多相油气生产井中涡轮流量计、含水率计和密度计的响应机理，认为生产测井结果受流型和流量变化的影响很大。

When the volume of liquefied petroleum gas is measured with a volumetric flowmeter and the relative density is measured manually with a pressure densimeter,the mass cannot be calculated in accordance with the existing standard for mass calculation.

当液化石油气体积采用容积式流量计测量，相对密度采用压力密度计手工测量的计量方式时，依据现有的质量计算标准，其质量无法进行计算。

This article analyzed eddy properties of fluids and optical fiber sensors of modulation uminous intensity, Utilize the micro-bending loss property and the result of interfering among many mould optic fibre modes of the optic fibers, have designed a kind of new-type flow of the flow and densimeter of measuring the rate of flow and density at the same time.

When measuring crude oil using flow meter plus on -line densimeter , the mass of crude oil shall equal to the product of its volume, density and a conbined correction factor.

在使用流量计结合在线密度计进行原油计量交接过程中，原油质量等于原油体积与密度及联合修正系数的乘积。

Error reduction can be achieved by improving the precision of flow meter, thermometer, water cut meter and densimeter,by reducing sample oil's deviation,and by correcting flow met...

要减少油量计量误差，就必须提高流量计、温度计、含水仪、密度计等仪表的准确度，减少所取油样的密度与含水率在某段计量时间内的非代表性平均值所引起的误差，用流量计系数来修正流量计的示值。

Therefore this quality index of objective technical standards, is to use the color reflection densitometer, traces of the printing ink layer in the printing field density and 75% of the net-point calculated density printing, printing k-value.

因此确定这项质量指标的客观技术标准，是使用彩色反射密度计，测出各印刷墨层的印刷实地密度和75%网点印刷密度，计算得出其印刷K值。

In this part, the densities of sodium benzoate, sodium nitrobenzoate, sodium chlorobenzoate and sodium methylbenzoate in DMFwater mixed solvents have been measured at 298.15K with an Anton Paar Model 55 densimeter. From these densities, apparent molar volumes and partial molar volumes have been calculated, transfer volumes from water to DMF-water mixtures and substituent contributions to the transfer volumes have also been obtained. Solvent and substituent effects are discussed in detail. The Scaled Partical Theory has been applied to the ternary solutions to evaluate the partial molar volumes of cavity formation and the volumes change associated with solute-solvent interaction.

选择了含有取代基团的芳香类有机电解质，主要是苯甲酸钠、硝基苯甲酸钠、氯苯甲酸钠和甲基苯甲酸钠的邻、间、对同分异构体作为研究对象，用DMA 55型振荡管密度计测定了它们在不同质量百分数组成的DMF-水混合溶剂中的密度，利用这些密度数据，计算了表观摩尔体积和偏摩尔体积，得到了这些单取代苯甲酸钠从水到DMF-水混合溶剂中的迁移偏摩尔体积及苯环上不同位置的取代基对迁移偏摩尔体积的贡献值，讨论了溶剂效应和取代基效应，并将定标粒子理论应用于此三元电解质溶液中。
