“…Similarly natural gas pressure measurements are performed by means of a piezoelectric transducer Sapfir-22DI-Vn. Analog electrical signals of these devices are converted into digital form by an analog-to-digital converter 15KA-60/8010 and enter a personal computer where on the basis of them measurement results are formed for temperature and pressure used subsequently in calculating the measurement result for natural gas density under working conditions [4].…”

“…Results of measuring the concentration of a natural gas component with a change in pressure and temperature are transferred to a personal computer, where taking account of the results of measuring natural gas pressure and temperature in a main pipeline (see for example processes for obtaining primary measurement information, Fig. 1, version a), the measurement result is calculated for natural gas density under working conditions [4]. Examples of this quasi-measurement process may also be preparation of the measurement results for conductivity, pressure, and temperature of an equilibrium vapor and gas phase, carried out automatically in the UK-RG.05 unit with indirect measurement of the concentration of nitrogen and helium if liquid rocket fuel.…”

Versions are considered of physicochemical measurements based on an indirect measurement method used in chemical and allied branches of industry. The main features are determined for these measurements and results of their systematization are provided.Physicochemical measurements based on an indirect measurement method may be separated into three types. i.e., direct, cumulative, and combined measurements. These types of measurements are performed in two stages: the first stage is preparation of primary measurement information, and the second stage is calculation of test substance properties based on measurements results [1-3].Just like physicochemical measurements based on a direct measuring method, the measured properties for a test substance are the concentration of its components or physicochemical properties. As primary measurement information there may be use of results of measuring test substance characteristics, differing in its measured characteristics, results of measuring substance sample characteristics and the results measuring the characteristics of a converted sample. Subsequently the characteristics of a test substance, its sample or converted sample, whose measurement results comprise the primary measurement information, will be called primary measurement characteristics.Generally, calculation of the results of measuring test substance characteristics is performed on the basis of certain equations [1-3]:

A data acquisition system has been developed for the determination of natural-gas composition and properties, ensuring low cost of the system and a measurement error not exceeding 2 %. The architecture of the system, measurement methods, and investigation results are described.Data acquisition systems for determining physicochemical composition and properties of substances are used widely in various branches of the industry, including the oil and gas branch [1]. Development of these systems involves conforming the characteristics of the systems to the set requirements applying general principles of synthesis of the systems [1, 2]: determining methodological support, devising structural and functional schemes, evaluating technical and economic characteristics, and selecting construction (synthesis) version.In [1], an examination was made of the use of the principle of determination of the methodological support to the systems, namely, analysis and development of procedures for measurement (PFM) of the physicochemical composition of natural gas (NG), but not enough light was shed on the use of the other principles of synthesis of the systems.Let us analyze the use of general principles of synthesis in developing an automated system for measuring physicochemical composition and properties of NG [1], especially use of the principle of devising structural schemes and its relationship with the principles of determination of the methodological support and devising functional schemes as well as the interrelation of all principles of synthesis of the systems. Basic Requirements of the SystemThe developed system must perform the following functions: measurement of concentrations of NG components [1] and determination of density ρ and specific heat of combustion q of the NG:where ρ j and q j are the density and specific heat of combustion of the component j of the NG; X j is the volume proportion of the component j of the NG; and J is the number of components to be determined (J = 17). The system designed for laboratory research must consist of domestically made technical devices. In this case, the criterion of synthesis was the lowest cost of the system and the constraints were guarantying relative errors of not more than 2 % in the determination of density and specific heat of combustion of the NG [1]. Analysis of PFM Based on Principle of Determination of Methodological Support to the SystemsSynthesis of the developed system includes analysis of the PFM of the physicochemical composition of the NG. Standard [3] is one of the key documents regulating the order of determination of the NG composition. In experimental studies of PFM of concentrations of the C 1 −C 5 and C 6 −C 8 group hydrocarbons, separation of NG components by gas chromatography was found to be unsatisfactory [1].
