<p>A mechanical automatic fluid consumption limiting apparatus for limiting flow through a primary flow line includes an actuating line, a control line, a rotary meter, a control assembly, an actuating valve, a diaphragm valve on the primary line, an eductor and an engagement controller. The actuating valve is rotated to an actuating position effecting closure of the diaphragm valve responsive to a predetermined quantity of flow through the rotary meter and mechanical response of the control assembly. An eductor diaphragm is positioned within the eductor and is connected to the engagement controller. The apparatus is configured to reset to its initial position and allowing resumption of flow through the primary line.</p> |
