ABSTRACT:
An ultrasonic measuring device for measuring the fluid flow of a high temperature fluid in a conduit. Ultrasonic transducers are mounted on first and second frames which have end portions hingedly coupled to one another. A tightening device at the other ends of the frames are used to secure the frames around the conduit carrying the fluid to be measured. Lead wires extend through hollow pipes between the ultrasonic transducers and connecting terminals at the outward ends thereof. Heat radiating fins may be provided at the outward ends of the pipes. With this construction, the outward ends of the pipes are at room temperature so that ordinary coaxial cables may be joined to the connecting terminals.
