corded and processed on an SM-4 computer. The readings of the correlation flow meter were compared with those of the diaphragm placed in the single-phase region of the helium stream. The relative deviation of the results of measurement of mass flow rate by the correlation flow meter and the diaphragm did not exceed 10%.Thus, it can be concluded that the diagnostic module with SHF resonators provides a relatively high accuracy, is very reliable and can be used in any cryogenic systems (having two-phase streams) to measure the vapor content, density and flow rate of vapor-liquid cryogenic media.
