FIELD: measuring equipment.
SUBSTANCE: disclosed is vibration meter (5) comprising a multichannel flow meter tube (130). Vibration measuring device (5) comprises measuring electronic device (20) and measuring unit (10) connected with possibility of data transmission with measuring electronic device (20). Measuring unit (10) comprises multichannel flow meter tube (130, 330, 430, 530) containing two or more channels (132, 332, 432, 532) for fluid medium surrounded by tube wall (134, 334, 434, 534). Two or more channels (132, 332, 432, 532) for fluid medium and wall (134, 334, 434, 534) of the tube have a single common structure. Driver (180) is connected to multichannel flow meter tube (130, 330, 430, 530). Driver (180) is configured to cause vibration of multichannel flow tube (130, 330, 430, 530). Two or more fluid channels (132, 332, 432, 532) and tube wall (134, 334, 434, 534) are configured to deform in the same direction as the common structure in response to the control signal supplied driver (180). Length of two or more channels (132, 332, 432, 532) for fluid medium is substantially equal to longitudinal length of vibrating part of multichannel flow tube (130, 330, 430, 530).
EFFECT: creation of flow meter, which accurately measures fluid medium flow rate.
