## Software for Calculating the Location Coordinates and Weighting Coefficients of Acoustic Paths of Ultrasonic Flow Meters

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).
