Abstract
A rotary and flow meter type liquid filling apparatus including a liquid reservoir tank that stores and supplies liquid to filling nozzles, and air supply paths for different amount of air supply and air discharge paths for different amount of air discharge being connected to the liquid reservoir tank. An air compressor is connected to the air supply paths, and the air discharge paths open into the atmosphere. A liquid pressure sensor disposed near the filling nozzles sense the increase or decrease of the liquid pressure inside a pipe that connects the liquid reservoir tank and liquid filling nozzles, and the electromagnetic valves provided on the air supply and air discharge paths are opened or closed, thus supplying air to and discharging air from the liquid reservoir tank so as to control the air pressure inside the liquid reservoir tank and the liquid pressure near the liquid filling nozzles.
