Get 63-2019: State Primary Special Standard of Units of Mass and Volume of Liquid in a Flow and of Mass and Volume Flow Rates of a Liquid

Measurement Techniques Aims and scope

Elements in the improvement of the metrological assurance of measurements of the units of the mass and volume of an entrained liquid and of the mass and volumetric flow rates of a liquid in the Russian Federation are set forth. Fundamentally new structural designs of key modules in the EU-3 standard flow diverter of GET 63-2019, the State Primary Special Standard of units of mass and volume of liquid in a flow and of mass and volume flow of a liquid, are considered. The structural designs are based on the results of numerical and physical simulation of hydrodynamic processes in forced streaming of a working liquid (water) in pipelines with different geometries of the flow-through part. The operating principles of the modules of stabilization and regulation of the water flow rates are evaluated. Innovative designs for the construction of the sensing elements of the flow diverter, the principle underlying the construction of the time diagram and the determination of the measurement time interval are presented. The metrological characteristics of GET 63-2019 are presented.
