Abstract: An apparatus for measuring fluid flow includes a housing, a first ultrasonic transducer, and a fluid flow path. The housing defines a smooth bore and a first cavity. The first cavity is separated from a fluid that flows through the smooth bore. The first ultrasonic transducer is disposed within the first cavity and transmits an ultrasonic pulse through the fluid. The fluid flow path extends from an upstream intake through the cavity.

Abstract: An apparatus for determining fluid flow in a pipe including a transit time chordal ultrasonic meter that eliminates dependence of meter factor on Reynolds number for measuring the flow through the pipe. The meter having a bore through which the fluid flows and a plurality of cavities with transducers disposed in the cavities which produce ultrasonic pulses that pass through the fluid and define multiple chords. The fluid velocity measured by clocking the pulses' time traveling diagonally upstream and downstream between pairs of the transducers. The transducers in the cavities isolated from the fluid flow in the bore by each cavity of the cavities having a liner which separates each cavity from the bore. A method.
