ABSTRACT:
A pressurized liquid conduit is broken or interrupted to provide an upstream inlet into a downstream outlet from a visual monitoring device. The device, which includes a collection chamber surrounding the conduit outlet and a transparent tube extending upwardly therefrom surrounding the upstream inlet is sealed in air tight relation around the liquid line on either side of the interruption. An air lock or bubble, greater in volume than the volume of the transparent tube, is contained in the chamber/tube assembly to maintain a constant pressure on the liquid collected in the chamber causing a controlled flow of liquid through the downstream side of the line. A baffle in the collection chamber disperses air bubbles, which might tend to form in the collected liquid, prior to the time the air bubbles reach the outlet in the chamber.
