    摘要: A flowmeter of the present invention is adapted to measure a flow velocity of a process liquid flowing through a supply pipe, and includes: a pair of ultrasonic oscillators located with a spacing therebetween of a predetermined distance along a flow direction of the supply pipe; a flow velocity calculating part calculating a flow velocity of the process liquid based on a first arrival time elapsed for an ultrasonic wave generated from one of the pair of ultrasonic oscillators to arrive at the other of the pair of ultrasonic oscillators and a second arrival time elapsed for an ultrasonic wave generated from the other of the pair of ultrasonic oscillators to arrive at the one of the pair of ultrasonic oscillators; and a bubble inclusion determining part determining, based on a time-varying amount of the calculated process liquid flow velocity, whether air bubbles are included in the process liquid.
