Abstract
An ultrasonic flow meter is equipped with a housing through which a liquid flows, and a pair of detection units disposed on opposite ends of the housing and including acoustic wave transmitting and receiving units capable of transmitting and receiving acoustic wave signals. Vibration generating mechanisms having vibration generating bodies arranged perpendicularly to the detection units are disposed on an outer circumferential side of the housing. In addition, when the flow rate of the liquid that flows through the housing is measured, the vibration generating bodies are energized and made to vibrate, such that gas bubbles, which adhere to cover members in contact with the liquid and that cover the acoustic wave transmitting and receiving units, are removed by the vibrations.
