The paper discusses flow metering devices for measuring the flow rate of two- or three-component flows of gas-liquid mixtures. The flow metering devices included in a multiphase flow meter and allowing determination of each component parameters of the flow is analyzed. A simple measuring system is presented, allowing measurement of the flow rate of a two-component gas-liquid flow. The factors of instability of a three-component gas-liquid flow formed in the line of a multiphase flow meter and affecting the errors of devices that are part of the flow meter and increasing the error of the flow meter as a whole are revealed.

The effectiveness of verification work largely depends on the choice of technical means of verification. The paper describes the use of the “TEST-GS/16” mobile modular calibration unit for checking gas meters, which differs from its analogues in the ability to set more than 1000 calibration points for gas consumption with a minimum set of critical nozzles and the possibility of self-monitoring of nozzle contamination, which makes it possible to timely identify unreliable calibration results.
Keywords: calibration unit; verification; gas meter; critical nozzles; gas flow measurement error.

The paper considers the major effect of digitalization on the managerial processes. In the course of the conducted studies it was determined that digitalization has a positive impact on the management. On the one hand, this impact is of clearly expressed positive nature and contributes to an increase in the production efficiency, reduction of costs, the competitiveness and stability of the business. On the other hand, digitalization causes automation of production and management process, brining jobs cuts thus provoking social tension. Judging by this fact, it is proposed to perform a gradual and smooth transition from traditional to digital technologies. The paper formulates recommendations, following which provides achievement of such stable balance.
Keywords: digitalization; management processes; innovative technologies; effective management strategies; data management.

A method for studying the electric and magnetic fields near an oil and gas well is proposed. Determination of soil electrical parameters near the well allows choosing the best method of electrical protection. This is especially true if there is a "black insert", extending from the well. The results of the study and technical decisions made on their basis, provide prolongation of the of trouble-free operation period in the "black insert" site.
Keywords: current density; electrical profiling; "black insert"; metal-plastic pipes (MPT); soil corrosion activity; magnetometry of underground pipelines; magnetic field; magnetic field induction.

The problem of identifying the hydraulic efficiency coefficients of pipelines of a gas transmission system (GTS) under stationary and non-stationary gas flow is considered. The coefficients are estimated by processing of pressure and flow measurements by standard measuring equipment. It is assumed that the measurement errors have a normal distribution with zero expectation. The developed methodology takes into account whole complex of measured parameters and their mode-technological relationships and uses the maximum likelihood method. The effectiveness of the developed methodology was tested on a real object – a complex gas distribution system of a looped structure. In the stationary case, the method of exhaustive search of expertly outlined variants was initially tested. In these variants, the efficiency coefficients of all pipelines of the system were assumed to be the same. It turned out that with an efficiency coefficient of 0,92, the calculations give almost the same mode as was actually observed. Thus, it is proved that for solving identification problems often it is not necessary to use advanced mathematical methods, but rather simple models of hydraulic calculations if the technological specificity of the object under study is known. To calculate unsteady flows, there used the adopted system of partial differential equations with unknown functions of temporal and spatial variables that determine pressure and flow along the arcs of the graph characterizing the topology of the pipeline system. This system is reduced to a simpler mathematical model of ordinary differential equations joining nodal pressures and flows at the end points of each arc of the graph (pipeline). The task of estimating the model coefficients is reduced to minimizing the likelihood function (the quadratic function of parameters) under constraints in the form of equalities following from gas flow equations. When using the adapted coefficients in the model, the calculation results for the GTS under consideration turned out to be very close to the actual values of the operating parameters.
Keywords: identification; control of gas transmission systems; flow in pipelines; stationary and non-stationary flow regimes; model with lumped parameters; theory of hydraulic circuits.
