FIELD: measurement equipment.
SUBSTANCE: provided vibratory flowmeter (5) for checking the metre includes an electronic measuring device (20) arranged to excite the vibration of the flow meter assembly (10) on a primary vibrational mode using the first and second actuators (180L, 180R), to define first and a second current (230) of the primary mode of the first and second actuators (180L, 180R) for a primary vibration mode and to determine the first and second voltage (231) of the primary mode response generated by the first and second strain sensors (170L, 170R) for a primary vibration mode to generate value (216) measuring stiffness by using the first and second currents (230) of the primary mode and the first and second voltage (231) of the primary response fashion, and validate operation of the vibratory flowmeter (5) using the value (216) of meter hardness.
EFFECT: checking the performance of the flowmeter with high accuracy.
