ultrasonic flow meter

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).

The accuracy of water flow rate measurement with an ultrasonic flow meter (UFM) is affected by pipeline conditions. On water pipelines, there is often no the required length of direct section, required by the device passport or regulatory documents. Therefore, we conducted experiments using UFM to measure water flow rate in the zone of influence of non-direct sections of the water pipeline. The flow rate was measured in two planes of the pipeline with an offset of 90 o and the average value was taken.
