An assembly for an ultrasonic flowmeter apparatus includes a housing having first and second opposite ends, an inlet and an outlet, a tube within the housing to define a passage in the housing, a wall within the housing to support the tube and to partition the housing into first and second plenums which are in flow communication through the passage of the tube and ultrasonic transducers mounted at the opposite ends of the housing to transmit ultrasonic signals in an axial direction through the tube.

An assembly for interposing an ultrasonic flowmeter apparatus in a small diameter pipeline comprising: a. a housing having first and second halves including first and second opposite ends respectively and said housing including an inlet for admitting a flow of liquid from a pipe to said first half and an outlet for discharging a flow of liquid from said housing from said second half; b. an open-ended tube supported within said housing to define an elongated straight passage therein, said tube being supported with its first and second open ends spaced respectively from said opposite ends of said housing; c. a wall within said housing separable from said first and second halves, said wall being the sole support of said tube, to partition the space enclosed by said housing into separate first and second plenums which are in flow communication through said open-ended tube; d. said first plenum being in direct flow communication with said inlet and formed relative to the adjacent first end of said tube so as to provide generally uniform flow to said tube; e. said second plenum being in direct flow communication with said outlet and formed relative to the adjacent second end of said tube so as to receive generally uniform flow from said tube; and f. a means for mounting ultrasonic transducers at said opposite ends of said housing to transmit ultrasonic signals in an axial direction through said tube.
