Abstract
This work develops a method for measuring the speed of an isothermal flow of liquid metal in a cylindrical channel. The method does not require calibration, is non-contact and is based on a correlation technique. The generation of pulses is carried out using rotating magnetic field inductors. Pulses of the axial velocity component are recorded by recording the electromagnetic response of local velocity meters. It is shown that with a small number of pulses, the value of the correlation function is small, which does not allow the velocity to be reliably measured, even with increasing pulse intensity. Conversely, a high degree of correlation for this technique is achieved with a significant increase in the number of pulses, which entails an increase in the duration of measurements.
