Abstract

A snap-on flow measurement system includes a block which attaches to a conduit and positions at least one transducer for launching and receiving acoustic signals along a precisely defined path through a flowing fluid. In one embodiment adapted to small tubes, two transducers are coupled to the tube and launch acoustic interrogation signals along an axial path within the tube. In another embodiment adapted to larger conduits, the transducers launch oblique signals which follow a zig-zag path through the fluid, reflecting off an inner wall of the conduit. In both embodiments, a channel defines a fixed position to hold the conduit aligned with the transducers.
