Method of producing ultrasonic flowmeter, ultrasonic flowmeter produced by the method and fluid controller having the ultrasonic flowmeter

Abstract

An ultrasonic flowmeter includes a measurement pipe through which a fluid flows, and two ultrasonic transceivers provided on outer side portions of the measurement pipe so as to be spaced apart from each other in an axis direction. In the method of producing the ultrasonic flowmeter, fabricating the measurement pipe in advance is fabricated, and then is set in a mold as an insert. Two transmitting bodies are formed by insert molding on the outer side portions of the measurement pipe so as to be spaced apart from each other in the axis direction, so that the two transmitting bodies are integral with the measurement pipe. The two ultrasonic transceivers are mounted on the two transmitting bodies, respectively.
