ABSTRACT:
Three fluidic control devices of special construction receive streams of air that are deflected to the atmosphere at predetermined intervals by means of jets of air controlled by valves and the liquid level in a container being filled as a filling machine moves through its cycle. At one point in the cycle, air pressure from one of the fluidic control devices causes the filling valve of the machine to open and remain open until a jet of control air is delivered to another of the fluidic control devices when the desired liquid level in the container is reached, whereupon those two control devices are vented to the atmosphere and the filling valve closes. If a container is not in filling position when it should be, there will be no blow-down through the level-sensing tube and the filling valve will not open.
