ABSTRACT:
A flow status monitoring method is disclosed for a gravity flow metering system employing a metering chamber separated by a movable diaphragm into two compartments, each with a valved inlet and valved outlet. The system alternately opens pairs of valves on opposite sides of the diaphragm at preselected time intervals to deliver a fixed increment of fluid. Each preselected interval is divided into a series of discrete sub-intervals, and flow monitoring information is generated by displaying a a discrete indicator representative of the sub-interval in which movement of the diaphragm across the chamber is completed.
