FIELD: invention is assigned for using in Coriolis's flowmeter.
SUBSTANCE: flowmeter using modes of multitude vibrations is calibrated for each chosen mode. They define density of substance flowing through flowmeter for each chosen mode, define influence of consumption on value of density for each chosen mode, calculate consumption with using values of density and influence of consumption on values of density for each chosen mode of vibrations and also with using phase or time delay, compare calculated consumptions and expose regime of error. In variant of execution they expose regime of error as consequence of comparison of values of density for each chosen mode of vibrations with compensational correction on consumption for each chosen mode.
EFFECT: inventions increase accuracy of measurement due to control over reliability of initial calibrated expense coefficient.
