Description

 Different methods are used to measure the consumption of fuel and energy resources, which lead to a wide range of measuring devices. Due to the provision of high measurement accuracy, a wide range of measured flows, the absence of additional pressure losses and the simplicity of the design, devices based on ultrasonic measurement methods are widely used in measuring practice. Such devices are easily integrated into automated information collection and transmission systems. The subject of research is a time-pulse single-beam ultrasonic flowmeter. The object of research is the process of determining the metrological characteristics of the flow meter. The purpose of the research work is to build a mathematical model and carry out simulation studies of an ultrasonic flow transducer with a complex trajectory of the measuring beam. The main tasks, tasks or problems that must be solved in order to achieve the goal: assessment of the current state of measuring the flow of liquid energy carriers by ultrasonic methods; development of a mathematical model of the static characteristics of the flow converter; mathematical modeling of flow converter operation; reproduction of the hydraulic channel using CFD technologies. Research methods, which are the basis of the work, are based on the use of mathematical modeling of physical processes, the basic laws of hydro-gas dynamics, methods of modern information technologies.
