Method for determination of flow rate of substance in a pipeline includes carrying out in pipeline simultaneous measurement of volumetric flow rate of substance with the firstand secondflow rate meters, with determination of equality or inequality of volumetric flow ratesandobtained with account of uncertainty (error) of measurements, issue of information on absence or presence of metrological failure at measurement of flow rates. Along with that in the same pipeline one carriers out measurement of volumetric flow rate -with the third flow rate meter, with comparison in pairs of volumetric flow ratesand,andobtained, with account of uncertainty (error) of measurements. |
