FIELD: measuring technique .
SUBSTANCE: flow meter comprises flow meter pipe, balancing rod oriented virtually parallel to the longitudinal axis of the pipe, first and second ends of the pipe connected with the opposite face sections of the pipe, casing provided with the balancing rod, connecting links of the casing connected with the first and second ends of the balancing rod to the inner wall of the casing, and at least one bend of the casing links. The method comprises exciting vibration of the rod and pipe in antiphase when fluid flows through the flow meter and changing the size of the connecting links of the casing in response to the temperature difference between the pipe and casing.
EFFECT: enhanced precision.
