Abstract
A flow meter device includes: a first vibrator, a second vibrator, a control unit, a timekeeper, and an arithmetic operation unit. The arithmetic operation unit is configured to: determine whether or not a time difference between a propagation time in the forward direction and a propagation time in the reverse direction is less than a predetermined value; calculate a propagation time correction amount based on the time difference if it is determined that the time difference is less than the predetermined value; and calculate a flow rate of the fluid by using the propagation time correction amount.
