[en] A procedure is proposed for determining the average velocity (flow rate) of water and/or steam for the case of essentially three-dimensional velocity profile in the pipe. The monitored system of steam flow rate measurement (SSRM) consists of three pressure tubes (PT). Monitoring of this system shows its functional reliability and, in particular, absence of erosion and mechanical failures of primary gauges. The signal lag of SSRM is less than 1-2 s. The quantitative differences of readings of pressure tubes located in the same pipeline cross-section were stated. Results of experiments modeling the Balakovo NPP steam pipelines are presented
