Abstract
An ultrasonic flowmeter apparatus, which can be mounted on a conduit flowing a fluid whose flow rate is to be measured, has two housing halves coupled swingably about an axis. Free ends of the housing halves include a clamp mechanism for closing and locking the halves in position. The halves have formed therein groovesand, respectively, and a pair of ultrasonic wave transmission and reception elements are provided on an inner wall of the groove. When the conduit is clamped between the grooves, the conduit is urged against the inner walls and deformed into a substantially square cross sectional configuration. An ultrasonic wave beam B is projected from one of the elements into a fluid passing through the conduit, the beam is reflected by an opposite surface of the conduit urged against the groove, and the reflected beam is received by the other element.
