Abstract
Gas bubbles in a moving fluid are collected in a chamber alongside the conduit carrying the fluid. In a preferred embodiment, an ultrasonic transducer cooperates with a reflector to create a standing ultrasonic wave pattern that is oriented at an acute angle to the horizontal axis of fluid flow. Bubbles gather at the troughs between the waves and then move between the pressure waves in the downstream direction to be collected in the chamber. Bouyant forces aid the movement of the bubbles in an upward direction. A gas permeable window at the top of the chamber allows removal of the collected bubbles.
