Abstract
To provide a clamp-on type ultrasonic flow sensor capable of preventing deterioration in measurement accuracy of a flow rate due to deformation of a pipe. Elastic couplants CPand CPformed to surround the outer circumferential surface of a pipe are fixed while being pressed on the pipe P by fixing inner surfaces FS of two clamp membersand. An ultrasonic wave is propagated through the elastic couplants CPand CPand fluid in the pipe between a first ultrasonic elementand a second ultrasonic element. A cross section of the fixing inner surfaces FS of the clamp membersandhas a shape of a regular even-numbered polygonal shape centering on the axis of the pipe.
