摘要

IMPROVEMENTS IN EXTRASENSIBLE WATER METERS, characterized by that, are constituted essentially by a proper meter, which is coupled with a valve that is kept closed by gravity and that is guided on the wall of the same chamber of the meter that will have two series of injection drills, some to act with small flow rates with the valve closed and others adding to the first to give way to the large flow rates that open the valve.
