Title: Ultrasonic flowmeter
Inventor: SHIMIZU KAZUYOSHI
IPC: G01F1/66
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a high-accuracy ultrasonic flowmeter in which the point of time of a reception in a reception-side transducer can be decided with high accuracy by reducing the influence of the component of ultrasonic waves which are not passed through a shortest propagation route between a transmitting transducer and the receiving transducer. SOLUTION: In an ultrasonic flowmeter, ultrasonic waves which are generated by a transducer T1 and a transducer T2 are radiated into a fluid which flows inside a conduit, the ultrasonic waves are recieved, and the flow velocity or the flow rate of the fluid is measured on the basis of the time required for their propagation, the amount of a frequency shift or the like. Then, in the ultrasonic flowmeter, an uneven part is formed in at least one point on the inner wall surface of the conduit in a part in which the ultrasonic waves are propagated. Regarding the component of the ultrasonic waves which are propagated so as to be deviated from a shortest propagation route, the point of time of their arrival to the reception-side transducer is delayed due to an increase in the number of times of their reflection on the inner wall surface.
