The article focuses on the development of software that allows you to calculate the location coordinates (x) and weighting coefficients (w) of acoustic paths of multipath chordal ultrasonic flow meters. The input data for the calculation are three (and in one case – four) parameters – the number of acoustic paths (N) ultrasonic flow meter, the type of numerical integration method, the internal diameter of the pipeline and degree (k) of weight function of Jacobi polynomial (if the Gauss-Jacobi numerical integration method was chosen). At the same time, the calculation is based on both table data (from mathematical directories) and on the analytical dependencies developed by the authors x = f(k) and w = f(k). The presence of such calculator software will simplify the work of developers, designers, scientists, and students who theoretically investigate the future influence of the geometric characteristics of ultrasonic flow meters on their metrological accuracy in various conditions of their operation
