FIELD: calibration of measuring instrument. SUBSTANCE: the flowmeter calibration system uses a great number of Coriolis mass flowmeters combined in two groups for calibration of the tested measuring instrument. At calibration of the tested measuring instrument the first and second groups of the flowmeters are connected for formation of a series connection with the source of feeding of fluid medium. EFFECT: produced a compact system of flowmeter calibration within a wide range of values of flow rate with a sufficient accuracy; the system should be a modular one. 32 cl, 5 dwg
