OPERATING FEATURES OF NATURAL GAS FLOW MEASUREMENT SYSTEMS

Energy resources accounting is a component of their rational consumption. The outdated equipment use that doesnot meet the requirements for measurement accuracy is one of the main issues in natural gas metering. Therefore, theissues of creating high-precision gas metering systems remain relevant. Gas metering units are used at various sites,from boiler houses to gas distribution stations and points that have different requirements for metrologicalperformances and characterized by different operating conditions.To improve the gas metering quality, it is necessary to control its physical and chemical parameters, such aspressure, temperature, density, gas composition, etc. Therefore, the creation of systems for measuring the flow andquantity of natural gas requires an integrated approach that includes recording, processing and monitoring allnecessary parameters using data transmission technologies.The automated collection lack and information conversion from the measuring system components makes itimpossible to remotely monitor its state.The aim of the work is a comparative analysis of existing systems for measuring the flow and quantity of naturalgas, as well as the requirements’ formulation for an automated system for measuring its parameters.The functioning features of existing systems, their structure and technical performances are discussed in thearticle. An analysis of current approaches to energy carrier accounting has been conducted.Particular attention is paid to the requirements for algorithms for processing and converting information receivedfrom automated systems for measuring natural gas flow rate, in addition to bringing the gas volume to base conditionsand calculating the consumed energy quantity. General requirements for such systems, which contribute to increasing the accuracy and reliability of measurements, are formulated.The prospects for further work are to improve an algorithm for the interaction between the measurement system components.
