“…These devices utilize ultrasonic waves to measure the volumetric flow rate based on the velocity of a fluid moving through a pipe [9]. In the engineering sector, ultrasonic flowmeters are used to monitor water flow in irrigation systems, HVAC systems, and industrial processes [10][11][12]. In the chemical industry, USFs are utilized to measure the flow rate of various chemicals and gases, including corrosive and abrasive substances [13].…”

This study investigates the impact of changes in velocity profiles on the measurement inaccuracies of gas flow streams detected by an ultrasonic flowmeter. The cross-sectional velocity profile was influenced by the downhill flow rate, causing variations in the shape factor coefficient. The flowmeter processing equation should consider the factor of shape coefficient variations. Consideration for these variations can result in errors in the measurement of the flow stream. The processing equation assumes a single, constant value for the shape factor coefficient, which can lead to inaccuracies. This article covers the inaccuracies of the transit-time ultrasonic flowmeter caused by a change in the velocity profile of the flowing gas, such as air. A realistic flow system was established with measured flow rates ranging from 43 m3/h to 225 m3/h. The findings of this study can serve as a valuable reference for the design and implementation of more accurate and efficient flow measurement systems that can enhance process efficiency.

“…The flow rate (mass or volume) is determined by measuring the mean velocity, which is a critical component of balancing devices and systems [1]. Therefore, it is essential to develop a highly accurate method for the measuring fluid flow velocities [2] [3]. Another desirable quality of the measuring device for the mean flow velocity is its non-invasive and non-contact capability.…”

“…Aspects of development within these drivers are widely covered in the works of modern researchers. At the same time, as a rule, there is the following division of the issues taken into consideration: digitalization of innovative processes of enterprises [1,2,3,4], digital transformation of energy enterprises [5,6,7,8], innovative development of representatives of the heat and power complex [9,10,11,12,13]. At the same time, the issue of digitalization of innovative processes of energy enterprises is not taken into consideration.…”

The article deals with the issues of digitalization of energy enterprises as representatives of one of the most important sectors of the Russian economy, which determines the possibility of developing other spheres of the national economy in order to ensure the economic security of the Russian Federation.As a priority direction of digitalization, the "digitalization" of innovation activity is justified, which allows to accelerate the pace of our country's innovation breakthrough and create favorable conditions for security in the economic sphere and at the national level. Based on the analysis of the existing experience of digitalization of energy enterprises, it is determined that there are currently a number of problems that prevent the effective implementation of measures in accordance with the developed program of digitalization of energy enterprises and their innovative activities.The low level of applied management methods, technologies and tools used for digital transformation of innovative activities of representatives of the energy industry is considered to be one of these problems. Organizational and managerial innovations are defined as a tool for bringing the applied management technologies and management methods to the necessary level.It is proved that the effective digital transformation of energy enterprises is possible only with the simultaneous application of innovations in the technological sphere and non-technological forms of innovation, which will contribute to creating favorable conditions for ongoing changes, complementarity and complementarity of transformation processes in order to obtain a synergistic effect that leads to a stronger positive innovative result. It is proposed to implement digitalization for the purposes of innovative development on the principles of balance, which digital technologies should find simultaneous application in the technological and managerial sphere.The implementation of changes in the proposed version will ensure the successful innovative development of energy enterprises on the basis of digitalization, which will contribute to the formation of the necessary conditions for economic security.
