The results of studies of the effect of varying degrees of turbulence flow-controlled media on the metrological characteristics of the flow nozzles. Established, in particular, that the change in the parameter Tu in the process flowmeter from 0 to 10% could bring in an additional error in the measurement of flow rate of about 10%.
